A highly digestible formula from a brand you can trust

Chewy Rating: 98% | Amazon Star Rating: 4.7 | High Fiber: Yes | Veterinarian Approved: Yes

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.

Made without poultry by-products

Available in a variety of different sizes, the 40lb bag offers great value for money compared to others on the market, especially given it’s chock full of high-quality ingredients.

With 100% farm-raised chicken taking out the number one spot, the list is rounded out by wholesome vegetables, like peas and crisp carrots, and high-fiber brown rice and beet pulp to aid digestion and provide a healthy dose of prebiotics for gut health. 

Food is love for this chef and that’s exactly the feeling your dog is going to get when they chow into this hearty and rich-tasting formula. The inclusion of plenty of poultry fat will give your fur baby a shiny coat and healthy skin and the omission of gluten and other known allergens makes this the perfect product for sensitive dogs.

The one thing worth noting is that corn is used as a filler in this formula. For most dogs that won’t be an issue and it’s certainly preferable to using animal by-products or some of the more common allergens but if corn is problematic for your pup then you may wish to look elsewhere. 

We love that a portion of the proceeds from every sale goes to The Rachael Ray Foundation, which helps animals in need. It’s a pretty great feeling to know that while you’re helping your dog, you’re also helping other animals receive the food, medical supplies and treatments that they need.

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.
