The best dog food for allergies is a well worth the slightly higher price tag if your beloved canine companion suffers from skin or stomach issues. Free from many common allergy-inducing ingredients, these wet and dry formulas are nourishing, soothing and will keep your furry friend feeling happy and healthy. 

Over the past decade you may have noticed a huge increase in the amount of specially formulated dog food for allergies. In fact, many of the best dog food dishes are allergy-friendly these days, which means there's plenty of choice available. But with all those options on the market, how do you know which formula is right for your furry friend?

Before you swap your dog over to an allergy-friendly formula though, it's worth checking with your vet to make sure that it really is your pup's food that's triggering their symptoms. While issues such as vomiting, diarrhea, stomach bloating, excess gas, itching and scratching, are all potential signs of a food intolerance, there can be other causes that are completely unrelated to diet. Your vet will be able to run some tests and rule out any underlying health conditions and if food is the cause, they'll also be able to help you transition your dog over to a suitable allergy formula.

When it comes time to choose a new dish, the first decision you'll want to make is between the best dry dog food and the best wet dog food. While there's often a lot of debate around which of these two reign supreme, you'll find that as long as you select a dish from a reputable brand, that both wet and dry food has everything your pup needs to thrive.

Once you've selected which type of food you think your dog would prefer, it's time to check out the ingredient list. Steer clear of common triggers such as corn, gluten, wheat, dairy, eggs, soy, and artificial colors, flavors and preservatives. We also recommend you stick with one protein and one vegetable as this is easier for the body to digest.

In terms of which proteins and vegetables to go for, we're huge fans of novel proteins, such as vension or duck, which tend to be far better tolerated in dog's with sensitivities than common proteins like beef and chicken. On the vegetable front, opt for nourishing options, such as sweet potato and pumpkin, both of which are known to be nice and gentle on the digestive tract. 

To help you select the right food for your furry friend, we've rounded up the best dog food for allergies lining the shelves in 2022. Let's open those packets, peel back those lids and take a closer look...

PetsRadar's pick of the best dog food for allergies

Royal Canin Veterinary Diet Gastrointestinal Low Fat

Best overall dog food for allergies

Item form: Wet | Age range: Adult | Key nutritional inclusions: Omega-3, prebiotics, antioxidant blend

Highly digestible proteins
Promotes healthy skin and coat
Antioxidants for a strong immune system
Contains grains and pork by-products

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. 

Rachael Ray Nutrish Just 6 Limited Ingredient Diet Dry Dog Food

Best budget dog food for allergies

Item form: Dry | Age range: All life stages | Key nutritional inclusions: Vitamins and minerals

Six easy-to-digest ingredients
Made without poultry by-products
Complete and balanced
Firm texture not suitable for dogs with dental issues

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.

There's also a wide range of vitamins and minerals on offer in the form of calcium, B12, Vitamin E, taurine and zinc to ensure that both your dog's bones and immune system stay in tip-top condition. 

You'll also find plenty of prebiotics and probiotics, which are ideal for dog's with sensitive stomachs and we love the addition of turmeric for joint health.

Omega-6 fatty acids and zinc for healthy skin
Nutrient-rich salmon is the first ingredient
Aimed at adult dogs

Purina is world renowned for good reason, and with the creation of this sensitive formula it has hit the mark again. 

Salmon is a great choice as the primary ingredient, with its high combination of Omega-3 and 6 fatty acids, which are gentle on the stomach and help to keep your dogs skin and coat in premium condition, being highly positive inclusions. They’re also great  for joint health and mobility so it’s a good choice whether your dog is young and energetic, or old and a possible arthritis sufferer. 

The inclusion of easy to digest carbohydrates like rice and oatmeal, which are kind to sensitive tummies and nourish the beneficial intestinal bacteria, also gets our seal of approval. Oatmeal is rich in antioxidants, has anti-inflammatory properties, and maintains blood sugar levels while contributing long-lasting energy. 

Moreover, we like the presence of live probiotics and natural prebiotic fibers, which both promote good digestion and aid a healthy immune system. For better value, you also have the option of purchasing this in a variety of different sized bags, with the 5lb size being something we would choose if you would like to give this a trial before committing. 

This formula is primarily focused on adult dogs, so if yours is a youngster then you might want to leave this now. This aside, this a great product that is definitely worth your time should your pup fit the right age demographic.

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. 

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.

Look for added vitamins, minerals, prebiotics and probiotics. Vitamins C and E and probiotic strains like lactobacillus and acidophilus are great for soothing the GI tract and ensuring good digestive health. Antioxidants from fruits and vegetables and Omega-3 fatty acids are also great additions. 

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.
