Choosing from amongst the best dog foods for allergies is a step you may find yourself having to take if your pup is suffering adverse reactions to traditional dog food.
Although the American Veterinary Medical Association (AVMA) estimates that only around 0.2% of canines have a food allergy triggered by ingredients found in the best dog food, for the small percentage of dogs that are affected, symptoms can profoundly affect their quality of life.
Common signs of dog allergies can include itchy skin, ear infections, vomiting and diarrhea. And while there’s no way to cure a food allergy, transitioning your pup to an allergy-friendly diet can go a long way in helping them feel more comfortable.
It’s important that you speak with your vet and get a proper diagnosis and management plan for your fur friend before changing their diet. However, if a food allergy is diagnosed, the below advice from Dr. Diana Hasler and Dr. Joanna Woodnutt will help assist you with choosing a suitable food for your pup.
Dr. Diana Hasler graduated with distinction from the University of Edinburgh Royal (Dick) School of Veterinary Studies in 2018. She has experience working as a small animal veterinarian in general practice, where she has treated many dogs, cats, rabbits, and rodents.
Dr Joanna Woodnutt qualified as a veterinarian from the University of Nottingham where she then went on to practice companion animal medicine in the Midlands.

Reasons to avoid
This veterinary prescription diet is suitable for dogs who have difficulties digesting or tolerating fats in their food, such as those prone to pancreatitis. It has a low fat content while still providing enough calories to maintain body weight, and it contains highly digestible proteins and prebiotics to support your dog’s digestive system. It also comes in a dry formulation. This diet should be fed under the supervision of a veterinarian.
Dr. Diana Hasler BVM&S MRCVS
Dogs that love wet food but suffer from a sensitive stomach are often forced to miss out on their favorite fare due to the high-fat content. Thankfully, it’s Royal Canin to the rescue with this veterinarian-approved low-fat formula which is both tasty and gentle on the tummy.
Hailed as a lifesaver brand by many a pooch parent, Royal Canin has an outstanding reputation for delivering high-quality nutrition that you can trust and this offering is no exception.
If your dog is prone to an easily upset stomach and bouts of vomiting and diarrhea then this is a great choice. Packed full of prebiotics to support the growth of good gut bacteria, dietary fibers for healthy digestion and Omega-3 fish oils to soothe the GI tract, this highly digestible formula is bound to get two paws up from your pooch.
Not only is this a great choice for supporting the stomach but it’s also a fantastic option if your dog suffers from frequent urinary tract issues as the formula works to prevent crystals from forming in the bladder. If you have an older dog that’s becoming more sedentary, you’ll love that the high-fiber and low-fat content boosts energy levels and prevents weight gain.
The one drawback to this product is the choice to include grains and pork by-products. Grains can be hard to digest for dogs with more severe allergies and pork by-products do lower the overall quality of what is otherwise a great ingredient list. Those small issues aside though, and this is still the standout choice when it comes to the best dog food for allergies.

This food contains lamb meal as its first ingredient. Although it contains chicken fat—a source of omega-3 and omega-6 fatty acids—most dogs with dietary sensitivities react to animal proteins, so this diet may still be suitable for some dogs with poultry intolerances. It also provides fiber in the form of brown rice and beet pulp to support digestive health.
Dr. Diana Hasler BVM&S MRCVS
If you’ve ever watched Rachael Ray cooking up a storm then you know how mouth-wateringly good her dishes can be and guess what? Now your pampered pooch can get in on the action too.
For a limited-ingredient kibble that won't break the bank, this formula is well worth considering. With just six easy-to-digest natural ingredients, plus a host of important vitamins and minerals, this is a recipe that's going to be gentle on your doggy's digestive system while still giving them everything they need to thrive.
Lamb meal is first on the list but please don't be put off by the word 'meal'. Basically, that's just a term that manufacturers use to describe a protein source (in this case, lamb) that has been dried and heat-treated then ground into a powder that is then turned into kibble.
Alongside lamb, you'll also find plenty of brown rice to give your pup the energy they need and beet pulp, which is a great source of fibre and ideal if you have a dog that struggles with constipation.
There's also a good amount of vitamins and minerals in this recipe, including omega fatty acids for a shiny coat and healthy skin, plus calcium and glucosamine for strong joints. At 20% protein and 13% fat, this is a well balanced and complete formula that will power your pooch through the day.
The kibble is free from fillers, artificial flavors, colors and preservatives and there's no added corn, wheat, soy or gluten. This is a clean formula that sticks to the basics and does them well, so if you're after a gentle but delicious kibble, this offering from Rachel Ray is worth trying.

We love that this grain-free formula steers away from common allergens and instead chooses to go with fiber-rich alternatives like lentils, which are gentle on the digestive tract. The recipe also omits eggs, another common trigger for dogs with sensitivities, and the inclusion of chelated minerals help maximize the absorption of valuable nutrients.

The addition of Taurine is great for eye and heart health and also stimulates bile acid in the stomach to help break down and metabolize fat.

Made in the USA by a family-owned and run company, Taste of the Wild has a standout reputation for ensuring their ingredients come from trusted and sustainable sources so you can rest assured you're giving your dog the best nutrition money can buy.

Reasons to avoid
If your dog has a problem with chicken, then you should consider a diet that is entirely free of this common protein. Take a good look at the ingredients in this meal and you'll find there's no chicken at all.
This is actually less common than you may imagine but here the main ingredient is deboned salmon followed by salmon meal. It also contains a host of healthy grains including brown rice as well as sweet potatoes which are gentle on the digestive tract.
Having a single source animal protein is important for dogs with allergies. Similarly, an absence of corn or soy ingredients is a must. With just nine key ingredients, you're on safe ground with Merrick's meal and you can be sure there are no eggs, dairy or artificial colors, flavors or preservatives.
The only downside is that your dog may not like it, not because it tastes awful but simply because some dogs have different preferences. If that's the case, it's a shame because this really is up there with the best.
The best dog food for allergies: FAQs
How to choose the best dog food for allergies
If your dog seems more interested in pawing at his ears or scratching her skin than hanging out with you and you’ve ruled out other causes, then it could be time to consider experimenting with their diet.
But with as many free-from foods on the market for dogs as there is for people, knowing where to start can be daunting. Thankfully, we’ve come up with a few simple guidelines that will help point you in the right direction.
Look for products that have short ingredient lists, generally with one form of protein and one form of carbohydrate which makes it easier to identify the potential allergen. While there are both risks and benefits, raw dog food is another option worth looking into. With few ingredients and zero additives, our guide to the best raw dog food is a great resource if you’re not sure where to start.
According to Dr. Joanna Woodnutt, “A good diet for allergies has a single protein source, such as lamb, and a single carbohydrate source. This reduces the chance of an allergen being present. If you don’t know what your dog is allergic to, the diet should contain a novel protein - one your dog hasn’t encountered before. Unusual proteins like ostrich and bison are sometimes used for allergy diets for this reason.”
Novel proteins and other ingredients can work well for a lot of dogs as they won’t have been over-exposed to them in the past. Think venison, rabbit, kangaroo, pheasant and bison, and gluten-free ancient grains and seeds like quinoa, millet, and chia.
Antioxidants from fruits and vegetables and Omega-3 fatty acids are great additions to your pup's diet and are well worth keeping an eye out for. "Dog foods high in omega 3s will also help the skin by reducing inflammation and building a healthier skin barrier," says Dr. Joanna Woodnutt. You'll also want to look for added vitamins, minerals, prebiotics and probiotics. Vitamins C and E and probiotic strains like lactobacillus and acidophilus are particularly great for soothing the GI tract and ensuring good digestive health.
Woodnutt also recommends considering opting for a hydrolysed diet. "The proteins are too small to cause an immune reaction," she explains. "They are great to use when the dog’s dietary history is unknown. They are also produced in a clean factory, to reduce the risk of cross contamination, as studies have shown the ingredients list on the back of the pack isn’t always accurate when it comes to what proteins could be inside."
Finally, if you’re noticing your dog displaying any of the symptoms of a possible allergic reaction be sure to consult your vet who will be able to help identify the cause and recommend the best course of treatment.
What foods should dogs with allergies avoid?
According to VCA Animal Hospitals, the most common food allergens in dogs are proteins, particularly those found in beef, chicken, chicken eggs, dairy, soy, and wheat gluten.
However, they note that almost any food ingredient has the potential to trigger an allergic reaction and while protein is the most common cause, other substances, such as artificial colors and preservatives, can also be responsible.
While it’s tempting to just start removing certain foods from your dog’s diet, it’s important that you seek the specialized advice and guidance of your vet to avoid accidentally omitting vital vitamins and minerals that your pup needs to thrive.
Your vet will be able to run tests that accurately determine exactly which ingredients are causing issues for your dog and work with you to formulate an appropriate diet for them.
What is the most common dog allergy?
As we’ve seen, food allergies in dogs are not as common as we might think, with the AVMA estimating that only 0.2% of pups will suffer from an allergic reaction that’s been triggered by something they’ve consumed.
So, if food allergies aren’t all that prevalent, what is the most common dog allergy? Well, according to a 2018 State of Pet Health Report from Banfield Pet Hospital, found that flea allergies in dogs have increased by 12.5% over the past 10 years, with environmental allergies up 30.7%.
As always, if you suspect your canine companion is suffering from an allergy, be sure to consult your vet who will be able to let you know exactly what you’re dealing with and outline an appropriate course of treatment.
