No-one really knows why certain ingredients in a dog's diet can cause the immune system to overreact but buying the best dog food for allergies will help ensure they remain happy and healthy. 

After all, the only way to be certain your four-legged friend doesn't become ill from eating particular foodstuffs is to avoid giving it to them in the first place. That way you'll prevent the risk of them producing antibodies that cause an allergic reaction. 

Food allergens are typically present in proteins and many manufacturers will cater for dogs unable to tolerate dairy, gluten, wheat, corn, soy, as well as a range of artificial colors and preservatives. The first step is to identify what's causing problems for your pooch either by observing reactions to certain foods or, preferably, by consulting a veterinarian. But don't worry: your dog can lead a perfectly normal life if they have an allergy. The important thing is spotting it.

Symptoms can vary. Some wet dog food or dry dog food can cause red itchy skin. You may also find they result in diarrhea, soft stools, bloated bellies, vomiting or excessive wind – all signs of a more serious allergy. Call a vet if you spot any of these issues and explain that they appeared shortly after eating. Tests can then be carried out to confirm an allergy.

From that point, in most cases, it's a mere matter of finding a formula suited to your dog's condition. Just be aware that there are lots of specially formulated dog food for allergies on the market so pay careful attention to the packaging of anything you buy. For skin allergies, food high in Omega 3 and 6 fatty acids are good choices, as are those containing nourishing anti-inflammatory ingredients such as sweet potatoes, oats and coconut oil.

With food affecting a dog's digestion, however, you should seek foods that have no artificial flavorings or preservatives and those with limited ingredients. That way you can be sure that you're removing anything that can lead to tummy problems. Finally, it may also be a good idea to muzzle dogs with severe problems when you're out on a walk to ensure they don't pick up anything on their travels.

best dog food for allergies: Royal Canin Veterinary Diet Gastrointestinal Low Fat

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 Natural Chicken & Veggies Recipe Dry Dog Food

Best budget dog food for allergies

Item form: Dry | Age range: All life stages | Key nutritional inclusions: Free from poultry by-products, fillers and wheat

Uses 100% farm-raised chicken
Made without poultry by-products
Free from gluten, artificial colors and preservatives
Contains ground corn as a filler

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. 

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. Now that’s what we call a win-win.

Purina Pro Plan Focus Adult Sensitive Skin And Stomach Salmon And Rice Formula

Best science-backed dog food for allergies

Item form: Dry | Age range: Adult | Key nutritional inclusions: Omega-3 and 6, zinc, calcium, glucosamine

Includes easy to digest carbohydrates
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.

Over 90% of reviews are from owners who say this kibble has transformed their dog, eliminating their health issues and allowing them to thrive. The limited negative reviews mostly point to dogs simply not enjoying the taste, but if you find this to be the case with your pooch, there are plenty of other great products in this guide to try out. 

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.
