If your dog is constantly scratching, licking their paws, or suffering from recurring ear infections, the problem might not be fleas or the weather. It could be something in their food bowl. Dog food allergies are more common than many UK pet owners realise, and they can cause real discomfort for your dog if left untreated.
At dogfoodsuk.com, we are an independent resource created to help UK dog owners find the best food for their dogs. In this guide, we explain what food allergies actually are, which ingredients trigger them most often, how to recognise the symptoms, and which hypoallergenic diets available in the UK might help your dog feel better.
We have researched veterinary advice from the PDSA, RSPCA, and leading veterinary dermatology resources to bring you a clear, practical guide. However, this article is for informational purposes only — always consult your vet if you suspect your dog has a food allergy.
What Is a Dog Food Allergy?
A dog food allergy is an abnormal immune system response to a specific ingredient in your dog’s diet. When a dog with a food allergy eats a triggering ingredient, their immune system mistakenly identifies the protein in that food as a harmful invader and launches an attack. This immune reaction is what causes the symptoms — typically skin irritation, digestive upset, or both.
It is worth understanding that true food allergies involve the immune system. This is different from a food intolerance, which we will explain in detail later. With a genuine food allergy, even a small amount of the offending ingredient can trigger a reaction.
According to the PDSA, food allergies can develop at any age, even if your dog has been eating the same food for years without any issues. This surprises many owners. A dog that has happily eaten chicken-based kibble for three years can suddenly develop an allergy to chicken protein.
Research suggests that food allergies account for roughly 1-2% of all skin conditions in dogs seen by UK vets, though the actual number may be higher since many cases go undiagnosed. Some breeds appear to be more predisposed, including Labrador Retrievers, West Highland White Terriers, Golden Retrievers, German Shepherds, and Cocker Spaniels. However, any breed can develop a food allergy.
The key thing to remember is that food allergies in dogs are a chronic condition. They rarely go away on their own. The most effective treatment is identifying and removing the trigger ingredient from your dog’s diet — which is where the hard work begins.
Most Common Food Allergens for Dogs in the UK
When it comes to dog food allergies, a relatively small number of ingredients are responsible for the vast majority of reactions. Understanding which ingredients are most likely to cause problems can help you make more informed choices about your dog’s diet.
Chicken
Chicken is the single most common food allergen for dogs in the UK. This may come as a surprise because chicken is also the most widely used protein source in commercial dog foods. The problem is exactly that — overexposure. When a dog eats chicken-based food every day for months or years, their immune system can eventually develop a sensitisation to chicken proteins.
If your dog is showing allergy symptoms and currently eats a chicken-based food, chicken should be one of the first ingredients you consider removing during an elimination trial.
Beef
Beef is the second most common food allergen for dogs. Like chicken, beef is heavily used in commercial dog foods and treats. Beef proteins are larger and more complex than some other meat proteins, which may make them more likely to trigger an immune response in sensitive dogs.
Many hypoallergenic dog foods specifically avoid both chicken and beef for this reason.
Dairy Products
Dairy, particularly cow’s milk and cheese, is a common allergen for dogs. Many dogs are also lactose intolerant, meaning they lack the enzyme needed to digest lactose properly. This can cause digestive symptoms that overlap with allergy symptoms, making diagnosis more complicated.
While a small amount of cheese as a treat is fine for most dogs, those with a dairy allergy or intolerance should avoid all dairy products entirely.
Wheat and Grains
Wheat is one of the most controversial ingredients in dog food. While true wheat allergies do exist in dogs, they are less common than allergies to animal proteins like chicken and beef. However, wheat gluten can cause problems for some sensitive dogs, and wheat is frequently included in lower-quality commercial foods as a cheap filler.
It is important to distinguish between a genuine wheat allergy and a wheat intolerance. A true wheat allergy involves the immune system, whereas an intolerance is a digestive issue. The All About Dog Food website provides detailed analysis of grain-free and wheat-free options if you want to explore alternatives.
Soy
Soy is increasingly used in commercial dog foods as a plant-based protein source. While soy is a complete protein and can be nutritious, some dogs develop allergic reactions to it. Soy is also a common ingredient in many treats and supplements, so if your dog is soy-sensitive, you need to check product labels carefully.
Eggs
Eggs are a less common but still recognised allergen for dogs. Egg proteins (particularly in the white) can trigger immune responses in sensitive individuals. Eggs are often used in dog treats, training rewards, and some commercial foods, so they are worth noting as a potential trigger.
Other Potential Allergens
Less commonly, dogs can develop allergies to lamb, fish, rabbit, pork, corn, rice, and even certain vegetables. The important principle is that any protein source can become an allergen if a dog is exposed to it frequently enough. This is why variety in your dog’s diet, or rotating between different protein sources, may help reduce the risk of developing allergies over time.
Signs and Symptoms of Food Allergies in Dogs
Recognising the signs of a food allergy in your dog is the first step towards getting them the help they need. The symptoms can be wide-ranging and sometimes develop gradually, which makes them easy to overlook or confuse with other conditions.
Skin-Related Symptoms
Skin problems are the most common sign of food allergies in dogs. These can include:
- Itchy skin (pruritus): This is the hallmark symptom. Your dog may scratch constantly, chew at their skin, or rub against furniture. The itching often affects the paws, ears, belly, armpits, and groin area.
- Red, inflamed skin: Areas that your dog has been scratching or licking may become red, sore, and sometimes infected.
- Hot spots: These are areas of moist, raw, inflamed skin that develop quickly and can become quite severe.
- Recurrent ear infections: Dogs with food allergies are prone to repeated ear infections (otitis externa). You may notice your dog shaking their head, scratching at their ears, or a discharge from the ear canal.
- Hair loss: Persistent scratching and inflammation can lead to thinning hair or bald patches.
- Chronic licking of paws: Many dogs with food allergies obsessively lick their paws, which can cause saliva staining (brownish discolouration) on the fur between their toes.
If your dog is experiencing recurring skin problems, food allergies are one possible cause — though environmental allergies, fleas, and contact allergies should also be investigated. Our article on rash on your dog’s belly covers some of the other common causes of skin irritation in dogs.
Digestive Symptoms
Some dogs with food allergies experience digestive problems rather than — or in addition to — skin symptoms. These can include:
- Chronic diarrhoea: Loose, frequent stools that persist despite changes in routine.
- Vomiting: Occasional or frequent vomiting, particularly after eating.
- Excessive flatulence: More gas than usual, which may have a particularly unpleasant smell.
- Bloating or abdominal discomfort: Your dog may appear uncomfortable after meals, pace around, or adopt a prayer position (front end down, rear end up).
- Changes in appetite: Some dogs with food allergies become reluctant to eat, while others maintain a normal appetite despite their symptoms.
Less Common Symptoms
In rarer cases, food allergies can contribute to secondary symptoms such as behavioural changes (due to chronic discomfort), recurrent urinary tract infections, or anal gland problems. The Pet Drugs Online guide on dog food allergies provides further detail on these less obvious signs.
The important thing is to look at the overall picture. If your dog has multiple symptoms that persist despite standard treatments like flea control, it is worth discussing the possibility of a food allergy with your vet.
Food Allergy vs Food Intolerance: What’s the Difference?
This is one of the most misunderstood areas of dog nutrition, and getting it right matters because the approach to each is different.
A food allergy involves the dog’s immune system. When the dog eats the offending food, their immune system produces antibodies (specifically IgE antibodies) against the proteins in that food. This triggers a cascade of inflammatory responses that typically affect the skin. Even a tiny amount of the allergen can cause a reaction, and the response can be rapid or delayed by hours.
A food intolerance does not involve the immune system. Instead, it is a digestive problem — the dog’s body cannot properly process or digest a particular ingredient. The most common example is lactose intolerance, where the dog lacks sufficient lactase enzyme to break down milk sugar. Symptoms are usually digestive (vomiting, diarrhoea, gas) rather than skin-related.
Here is a simple comparison:
- Food allergy: Immune system response; primarily causes skin symptoms (itching, redness, ear infections); small amounts can trigger a reaction; can develop at any age.
- Food intolerance: Digestive system issue; primarily causes gastrointestinal symptoms (vomiting, diarrhoea, bloating); usually requires a larger amount to trigger symptoms; often related to specific food components (like lactose or certain fats).
The practical difference matters because food allergies typically require a strict elimination diet to identify the trigger, while food intolerances may be managed by simply reducing the amount of the offending ingredient or using a food that is easier to digest. Both conditions benefit from veterinary guidance, and the symptoms can overlap significantly, making professional diagnosis essential.
How Vets Diagnose Food Allergies
Diagnosing a food allergy in dogs is not straightforward. There is no quick blood test or skin test that can definitively confirm a food allergy. The only reliable method is an elimination diet trial, supervised by your vet.
The Elimination Diet (Food Trial)
The elimination diet is considered the gold standard for diagnosing food allergies in dogs. Here is how it works:
Step 1: Choose a novel protein diet or hydrolysed diet. Your vet will recommend either a food made with a protein source your dog has never eaten before (novel protein) or a food where the proteins have been broken down into fragments so small that the immune system cannot recognise them (hydrolysed protein). Hydrolysed diets are generally considered more reliable for diagnosis.
Step 2: Feed only the elimination diet for 6-8 weeks. This is the critical part. During the trial, your dog must eat absolutely nothing else — no treats, no table scraps, no flavoured medications, no dental sticks. Even a single treat containing the allergen can invalidate the entire trial. The PDSA’s guide on conducting a food trial provides detailed instructions on how to carry this out properly.
Step 3: Monitor symptoms. If the symptoms improve significantly during the trial period, this suggests a food allergy is likely. However, improvement alone is not enough for a definitive diagnosis.
Step 4: Reintroduction (challenge test). After the trial, your vet may recommend gradually reintroducing the original food or specific ingredients one at a time. If symptoms return when a particular ingredient is reintroduced, that confirms the allergen. This step is important because it distinguishes between a genuine food allergy and a coincidental improvement.
Why Blood Tests and Skin Tests Are Not Reliable
Some vets and online services offer blood tests or intradermal skin tests for food allergies. While these tests can be useful for detecting environmental allergies (like pollen or dust mites), they are generally considered unreliable for diagnosing food allergies. The Veterinary Dermatology Clinic advises that false positives are common with these tests, leading to unnecessarily restricted diets.
The elimination diet remains the most accurate method available. It requires patience and discipline from both you and your dog, but the results are far more meaningful than any test currently on the market.
When to See Your Vet
If your dog has persistent itching, recurrent skin or ear infections, or chronic digestive problems that do not respond to standard treatments, make an appointment with your vet. Mention that you are concerned about a possible food allergy, as this will help your vet plan the most appropriate diagnostic approach. Referral to a veterinary dermatologist may be recommended in complex cases.
Best Hypoallergenic Dog Foods in the UK
Once a food allergy has been diagnosed (or strongly suspected), the next step is finding the right diet for your dog. There are three main categories of hypoallergenic dog food, each with different approaches to reducing the risk of allergic reactions.
Limited Ingredient Diets
Limited ingredient diets (LIDs) are made with a shorter list of ingredients, which reduces the chance of your dog encountering a trigger. The idea is simple — fewer ingredients means fewer potential allergens. These diets typically feature a single protein source and a single carbohydrate source.
James Wellbeloved Hypoallergenic is one of the most well-known limited ingredient brands in the UK. Their recipes use turkey, duck, or fish as the primary protein, alongside rice and simple carbohydrate sources. They exclude common allergens like beef, wheat, and soya.
Pros: Widely available in UK pet shops and online. Good range of flavours. Reasonably priced compared to prescription diets. Most dogs enjoy the taste.
Cons: Contains rice, which some highly sensitive dogs may react to. Not suitable as a diagnostic tool for elimination trials since the ingredients are still intact proteins.
Simpsons Premium Sensitive offers grain-free recipes with 70% duck or fish content and a carefully limited ingredient list. It is made in the UK and has a strong reputation among dog owners who manage allergies through diet.
Pros: Very high meat content. Completely grain-free. No artificial colours or preservatives. Made in Yorkshire.
Cons: Higher price point. Only available through independent pet shops and select online retailers. Limited flavour options.
Eden 80/20 is a high-meat, limited ingredient food that uses single protein sources. It is one of the highest-quality commercial foods available in the UK and is popular among owners of dogs with sensitivities. Read our full review on the best grain-free dog foods in the UK for more detail.
Pros: Exceptional ingredient quality. Very high meat content. Broad range of protein options. Free from grains and common fillers.
Cons: Expensive. May be overkill for dogs with mild sensitivities. Some dogs find the high meat content too rich if transitioning from a lower-quality food.
Novel Protein Diets
Novel protein diets use protein sources that your dog is unlikely to have encountered before. If your dog has been eating chicken and beef-based foods, switching to something like venison, duck, rabbit, or fish provides new proteins that the immune system has not yet sensitised to.
Fish 4 Dogs Finest is a single-protein fish-based food that is naturally grain-free and rich in omega-3 fatty acids. Fish is an excellent novel protein choice because it is less commonly used in standard dog foods than chicken or beef. The omega-3 content also helps support skin health, which is beneficial for dogs with allergy-related skin problems.
Pros: Excellent omega-3 content for skin and coat health. Single protein source. Naturally hypoallergenic. Good palatability for most dogs.
Cons: Some dogs do not enjoy the fishy smell. Can be expensive. Limited to fish-based recipes, so not suitable if your dog is allergic to fish.
Burns Sensitive uses simple, natural ingredients and was originally formulated by a veterinary surgeon. Their sensitive range uses duck, fish, or pork as the protein source, alongside brown rice. It is designed to be gentle on the digestive system and is a good option for dogs with mild to moderate sensitivities.
Pros: Vet-formulated. Very digestible. Widely available. Good value for money. Contains no artificial additives.
Cons: Contains rice, which some dogs may react to. Lower meat content compared to premium grain-free alternatives.
Hydrolysed Protein Diets (Prescription Only)
Hydrolysed protein diets are the most effective type of food for both diagnosing and managing food allergies. In these diets, the protein molecules are broken down (hydrolysed) into fragments so small that the dog’s immune system cannot recognise them as allergens. This means the dog gets complete nutrition without triggering an allergic response.
These diets are only available through your vet and require a prescription. They are the recommended choice for elimination diet trials because they virtually eliminate the risk of an allergic reaction during the testing period.
Royal Canin Hypoallergenic is one of the most widely prescribed hydrolysed diets in the UK. It uses soya protein that has been extensively hydrolysed, along with purified starch sources. It has been clinically tested and is trusted by veterinary dermatologists across the country.
Pros: Clinically proven for elimination diet trials. Extremely low risk of allergic reaction. Available in both dry and wet formats. Highly palatable for most dogs.
Cons: Prescription only (requires vet visit). Contains soya (though hydrolysed). More expensive than over-the-counter hypoallergenic foods. Not the most natural ingredient list.
Hill’s Prescription Diet z/d is another leading hydrolysed protein diet. It uses chicken protein that has been broken down into microscopic fragments, along with purified carbohydrates. It is designed for both the diagnosis and long-term management of food allergies.
Pros: Clinically validated. Available in dry and canned formulas. Contains added antioxidants for immune support. Widely stocked by UK veterinary practices.
Cons: Prescription only. Premium price. Some dogs may not find it as palatable as non-prescription alternatives. Long-term feeding may be less appealing for owners who prefer natural ingredients.
The Virbac guide on hypoallergenic dog food diets provides excellent further reading on the differences between these diet types and how they work at a biological level.
Best Dog Food Ingredients for Dogs with Allergies
When choosing a food for a dog with allergies, certain ingredients and nutrients can make a real difference to their health and comfort.
Omega-3 Fatty Acids
Omega-3 fatty acids, particularly EPA and DHA from fish oil, are one of the most beneficial nutrients for dogs with food allergies. They have natural anti-inflammatory properties that can help reduce skin inflammation and itching. Many vets recommend omega-3 supplementation alongside dietary changes for allergic dogs. Fish-based foods like Fish 4 Dogs and anti-inflammatory foods for dogs are naturally rich in these beneficial fatty acids.
Probiotics and Prebiotics
The gut-skin connection is increasingly recognised in both human and veterinary medicine. A healthy gut microbiome supports a strong immune system and may help reduce the severity of allergic reactions. Foods that include probiotics (beneficial bacteria) and prebiotics (food for those bacteria) can support digestive health and overall wellbeing. Scrumbles is a UK brand that specifically focuses on gut-friendly recipes with added probiotics, and is worth considering for dogs with both allergy and digestive concerns.
Single Protein Sources
Foods that use a single, clearly identified protein source make it easier to identify and avoid allergens. If a food contains “chicken meal” as its only animal protein, and your dog reacts to it, you know exactly what to eliminate. Multi-protein foods (those containing chicken, beef, and lamb, for example) make this process much harder.
Natural Antioxidants
Ingredients like sweet potato, blueberries, spinach, and cranberries provide natural antioxidants that support the immune system and help reduce oxidative stress. Foods that include these ingredients naturally, rather than through synthetic vitamin supplements, tend to be better quality overall.
Ingredients to Avoid if Your Dog Has Allergies
Alongside knowing what to look for, it is equally important to know what to avoid. If your dog has been diagnosed with a food allergy or you suspect one, keep these ingredients on your watch list.
Common allergens: Chicken, beef, dairy, wheat, soya, and eggs should be the first ingredients you scan for on any dog food label. If your dog has a confirmed allergy to a specific protein, you need to avoid that protein in all forms — including treats, supplements, and flavoured medications.
Artificial additives: Artificial colours, flavours, and preservatives can irritate sensitive dogs and may exacerbate allergic symptoms. While they are not themselves allergens in the traditional sense, they add unnecessary chemical burden to a dog that is already dealing with immune system stress.
Generic protein sources: Ingredients listed as “meat meal,” “animal fat,” or “poultry digest” are red flags because they do not specify the exact protein source. If your dog is allergic to chicken, a food containing “poultry meal” could still trigger a reaction because you do not know exactly what is in it.
Hidden allergens in treats: This is a common trap. Many dog treats contain beef, chicken, or wheat even when the main food does not. Always read treat labels carefully, and during an elimination diet trial, avoid all treats entirely unless specifically approved by your vet.
Table scraps and human food: During an elimination trial, and ideally ongoing, avoid feeding your dog scraps from your own meals. Human food often contains multiple ingredients, seasonings, and sauces that could contain hidden allergens.
How to Transition Your Dog to a New Diet Safely
Switching your dog to a hypoallergenic diet needs to be done gradually. A sudden change can cause digestive upset, which makes it harder to tell whether any ongoing symptoms are due to the allergy or the diet change itself.
We have a detailed guide on how to switch dog food safely, but here is a quick overview of the recommended approach:
Days 1-3: Mix 75% of the current food with 25% of the new food.
Days 4-6: Mix 50% of each.
Days 7-9: Mix 25% of the current food with 75% of the new food.
Day 10 onwards: Feed 100% of the new food.
This gradual transition takes about 10 days, though some dogs with sensitive stomachs may need two to three weeks. Watch for any changes in stool quality, appetite, or behaviour during the transition. If your dog develops loose stools or refuses to eat, slow the transition down.
It is particularly important to follow this gradual approach when moving to a hydrolysed protein diet, as these have a very different taste and texture compared to standard dog foods. Some dogs need extra encouragement to accept them — warming the food slightly or mixing in a small amount of vet-approved flavour enhancer can help.
Can Raw Food Help Dogs with Allergies?
Raw feeding is an increasingly popular approach among UK dog owners, and some people find it helps dogs with food allergies. The potential benefits include complete control over ingredients, no artificial additives, and the ability to feed novel proteins that may not be available in commercial foods.
A raw diet can make it easier to follow a strict elimination diet because you know exactly what your dog is eating — no hidden ingredients, no generic protein sources, and no mystery additives. If you suspect your dog is allergic to chicken, for example, you can feed a single-protein raw diet using venison or rabbit, giving you complete confidence about what is in the bowl.
However, raw feeding is not without risks. The Food Standards Agency and the RSPCA both highlight concerns about bacterial contamination (particularly Salmonella and E. coli) in raw pet foods, and the potential risk to vulnerable people in the household. Raw feeding also requires careful attention to nutritional balance to avoid deficiencies or excesses over time.
If you are considering raw food for your allergic dog, read our comprehensive guide to the best raw dog food in the UK, which covers the pros, cons, safety considerations, and top brands. For dogs with allergies, commercially prepared complete raw diets from DEFRA-approved manufacturers are a safer option than homemade raw recipes, as they have been formulated to meet nutritional standards set by FEDIAF (the European Pet Food Industry Federation).
Always discuss any major dietary change with your vet, particularly if your dog is currently on medication or has other health conditions alongside their allergies.
Additional UK-Specific Hypoallergenic Brands Worth Considering
Beyond the brands already mentioned, several other UK-specific options are worth looking at if your dog has food allergies:
Purina Pro Plan OptiDerma is a salmon-based food specifically formulated for dogs with sensitive skin and coat. While it is not a hydrolysed diet, the high omega-3 content from salmon helps support skin barrier function and reduce inflammation. It is available without a prescription and is more affordable than veterinary hydrolysed diets.
Scrumbles is a UK brand that focuses on gut health, using prebiotics and probiotics alongside carefully selected ingredients. Their recipes avoid common allergens and use a single protein source. The addition of slippery elm, known for its soothing properties on the digestive tract, makes this a good option for dogs with both skin and digestive symptoms.
Forthglade Cold-Pressed offers gently processed dog food made with high-quality UK-sourced ingredients. Cold-pressed foods retain more of their natural nutrients compared to traditional kibble, and Forthglade’s limited ingredient approach makes them suitable for sensitive dogs. Their recipes feature single proteins like duck, lamb, or salmon.
You can compare prices for all these brands on Amazon UK, though we always recommend checking independent pet retailers too, as specialist shops often stock a wider range of hypoallergenic options and can offer personalised advice based on your dog’s specific needs.
FAQs About Dog Food Allergies
Can dogs develop food allergies at any age?
Yes. Food allergies can develop at any stage of a dog’s life — in puppies, adult dogs, and seniors. Many dogs develop allergies after eating the same food for months or years without any problems. There is no specific age at which dogs become immune to developing new allergies.
How long does an elimination diet take?
A properly conducted elimination diet typically takes 6 to 8 weeks before you can reliably assess whether symptoms have improved. Some vets recommend up to 12 weeks for dogs with severe or long-standing symptoms. It is important to be patient and strict during this period — any deviation can invalidate the results.
Are grain-free foods better for dogs with allergies?
Not necessarily. While some dogs with wheat allergies benefit from grain-free foods, true grain allergies are less common than protein allergies (chicken and beef). Many grain-free foods simply replace grains with other carbohydrates like potato or sweet potato, which can also cause reactions in sensitive dogs. The important thing is identifying the specific allergen, rather than assuming grains are the problem. Our guide on the best grain-free dog foods in the UK covers this topic in more depth.
Can I test my dog for food allergies at home?
No reliable at-home food allergy test exists for dogs. Hair analysis tests, saliva tests, and blood tests sold directly to consumers have not been scientifically validated for diagnosing food allergies in dogs. The only reliable method is a vet-supervised elimination diet trial. Save your money on unproven tests and invest in a proper consultation with your vet instead.
Is a food allergy the same as coeliac disease in humans?
No. True coeliac disease (a severe autoimmune reaction to gluten) is extremely rare in dogs and has only been documented in a specific lineage of Irish Setters. What many people describe as a “grain allergy” in dogs is usually either a general sensitivity to a specific grain, or more commonly, a protein allergy where grains are not the culprit at all.
Can my dog outgrow a food allergy?
It is uncommon but not impossible. Some dogs may become less reactive to a specific allergen over time, particularly if they have avoided it for a long period. However, most food allergies in dogs are lifelong conditions that require ongoing dietary management. Do not assume an allergy has been outgrown without veterinary testing through a controlled food challenge.
Should I give my allergic dog supplements?
Omega-3 fish oil supplements are often recommended by vets for dogs with food allergies, as they help reduce skin inflammation and support the skin barrier. Probiotic supplements can also support gut health, which is linked to immune function. Always consult your vet before starting any supplements, as the wrong dose or type could cause more harm than good.
Are hypoallergenic foods more expensive?
Generally yes. Limited ingredient diets, novel protein foods, and hydrolysed protein prescription diets all tend to cost more per kilogram than standard dog foods. However, the cost of not treating a food allergy — including repeated vet visits, medications, ear treatments, and specialist shampoos — can quickly add up. Investing in the right diet from the start often saves money and improves your dog’s quality of life in the long run. Compare prices on Amazon UK and specialist pet food retailers to find the best deals.
What if my dog will not eat the new hypoallergenic food?
Palatability can be an issue, particularly with hydrolysed protein diets which have a different taste and texture. Try warming the food slightly, adding a small amount of warm water to release the aromas, or asking your vet about prescription flavour enhancers. Never starve a dog into accepting a new food — if they refuse completely, speak to your vet about alternative options.
Conclusion
Dog food allergies can be frustrating to deal with, but they are manageable once you understand what is causing them. The most important steps are recognising the symptoms, getting a proper veterinary diagnosis through an elimination diet, and finding the right long-term diet for your dog.
Whether your dog needs a limited ingredient diet, a novel protein food, or a prescription hydrolysed diet, there are good options available in the UK for every budget and situation. Brands like James Wellbeloved, Burns, Fish 4 Dogs, and Scrumbles offer accessible over-the-counter choices, while Royal Canin and Hill’s provide clinically validated prescription options for more severe cases.
