Usually, it's dog food ingredients first to be blamed when a dog shows food allergy symptoms. While it's not always an allergic reaction to dog food per se, your veterinarian may ask you to switch your pet's to a hypoallergenic dog food brand, or a limited ingredient dog food formula.

Signs of a dog's food allergy are typically itchy skin and digestive disorders. The most common allergens in dog food are proteins: beef, lamb, chicken (and chicken eggs), diary products as well as soy or gluten. While food allergies in dogs cannot be eliminated completely, they can be managed with a hypoallergenic diet.

Fortunately, there's a number of good hypoallergenic dog foods available today that make feeding an allergic dog fairly easy. They've been shown to be very effective at what they claim to do. Below we'll discuss such dietary approach, how to pick these foods and do a best hypoallergenic dog food review round-up.

What Makes Dog Food “Hypoallergenic”?

Hypoallergenic dog food is easier for dogs to digest and absorb due to its ingredient composition, which is more rare and unique compared to some popular brands. This is why these diets are often more expensive than regular brands (but cheaper the prescription foods from vet clinics).

Note that not every hypoallergenic dog food formula will work for every pet with food allergies. That said, they are still likely to be better than your standard brand. Although there is no officially defined term that governs laws regarding this part of dog food labels, a dog food is considered hypoallergenic when it contains:

  • A limited (very small) number of ingredients
  • Novel ingredient(s) that are high quality
  • Least offending ingredients (less likely to cause allergic reactions)

Most top rated hypoallergenic dog foods are prescription dog food diets that pet owners can buy from their vets. However, prescription diets can be very costly, and most pets don't really need to pay 3-5 times more for their dog food because over-the-counter brands will have same or similar ingredient composition.

Hypoallergenic Dog Food Labels

The term “hypoallergenic” actually has no legal definition in the pet food industry.

Also, hypoallergenic diets rarely name themselves using this term, but rather opt for a “limited ingredient diet” terminology which makes them more appealing to a wider range of consumers, since not all dogs with food sensitivities are allergic but may have other issues. These food formulas for dogs with allergies have been developed based on several scientific studies showing allergy sources (source).

When a hypoallergenic dog food is limited in ingredients, it will typically have under 10 ingredients, most commonly 5-7 ingredients. Some of the best limited ingredient dog foods make it easy to pin down allergens, i.e. causation. They may also contain hydrolyzed protein source, which was shown to be effective in dog food allergies (source).

Novel ingredients in hypoallergenic pet foods are something a sensitive stomach dog is much less likely to be allergic to, but that is not always guaranteed. For some dogs with food allergies, sensitive stomach brands can be a good option. However, only testing and/or elimination diet can tell you exactly what your dog is allergic to (source).

Best Limited Ingredient Dog Foods as Alternatives

The above list of five best hypoallergenic dog food brands contains the most popular based on their ingredient composition, but most of them are expensive. Below are ten cheap limited ingredient dog foods for dogs with food allergies that are more affordable.

Instinct Limited Ingredient Diet ($3.2/lb)6. Instinct Limited Ingredient Diet ($3.2/lb) – one of the most expensive hypoallergenic dog food brand out there but also one with the highest success rate, Instinct limited ingredient dog food contains only two ingredients – one animal protein and one vegetable source. No other dog food formula offers this. It's one of the best limited ingredient dog food brands due to its simplistic formula with no fillers, grains or otherwise unknown or suspicious ingredients. Its easily digestible protein source makes it perfect for majority of dogs with food allergies and food sensitivities.

CANIDAE Grain Free PURE Land Formula ($2.5/lb)7. CANIDAE Grain Free PURE Land Formula ($2.5/lb) – the company are well-known for sourcing unique, high quality ingredients for their dog food formulas. This one contains bison as the main source of protein and six additional ingredients made up of wholegrains. This may not be suitable for every dog with allergies since the number of ingredients is still longer than some other formulas.

Natural Balance L.I.D. Limited Ingredient Food ($2.1)8. Natural Balance L.I.D. Limited Ingredient Food ($2.1) – this grain free formula contains premium quality protein and carbohydrate sources (no grains). However, even though Natural Balance is known for their best limited ingredient dog food formulas, this one may not be the top option for a lot of dogs due to comparably higher number of ingredients. Nevertheless, the recipe is very simple and easy to digest.

Rachael Ray Nutrish Just 6 Natural Food ($1.07/lb)9. Rachael Ray Nutrish Just 6 Natural Food ($1.07/lb) – a very similar formula to the above mentioned Canidae, this hypoallergenic dog food may be a good alternative to Natural Balance formula (and vice versa). The recipe is simple with only six ingredients and added vitamins and minerals, no byproducts or fillers, but it does contain grains, ground and brown rice.

BLUE Basics Limited Ingredient Diet ($2.08/lb)10. BLUE Basics Limited Ingredient Diet ($2.08/lb) – another one of the best hypoallergenic dog foods due to its low number of ingredients, high protein source and no grains. While some of the BLUE dog foods have been under heat in the past, their limited ingredient formula is still one of the best hypoallergenic dog food brands you can find, but it may not fit every dog with sensitivities.

Natural Balance Limited Ingredient High Protein Food ($2.5/lb)11. Natural Balance Limited Ingredient High Protein Food ($2.5/lb) – this hypoallergenic dog food is a better alternative to the above mentioned Natural Balance limited ingredient dog food due to larger percentage of high quality protein (32% real beef) in it. However, it also comes with hefty price tag when compared to other best hypoallergenic dog food brands. It doesn't contain any grains either.

The Honest Kitchen Hope Dehydrated Minimalist Food ($10/lb)12. The Honest Kitchen Hope Dehydrated Minimalist Food ($10/lb) – the most expensive hypoallergenic dog food brand on this list. The Honest Kitchen company hasn't been very popular among dog owners, which is unjust since their human grade, FDA approved dog foods are actually very high quality, and this formula is easily one of the best hypoallergenic dog foods out there. It's one of the best rated dehydrated foods resembling raw feeding and only contains six quality ingredients.

Merrick 1 Count Limited Ingredient Diet ($2.5/lb)13. Merrick 1 Count Limited Ingredient Diet ($2.5/lb) – one of the best grain free dog foods out there, Merrick is a favorite among pet owners looking for high protein dog food with no grains. Their limited ingredient dog food formula is another winner with 34% real chicken and the rest filled with five quality ingredients. The recipe, however, will not fit a lot of dogs with food sensitivities and allergies.

NUTRO Limited Ingredient Diet ($2.5/lb)14. NUTRO Limited Ingredient Diet ($2.5/lb) – although NUTRO's dog foods are generally high rated five star brands, they're not known for their limited ingredient formulas or best hypoallergenic dog foods, and this one as well is mostly an alternative if you can't pick any other limited ingredient dog food brand. It contains ten ingredients, no grains and claims to have eliminated popular food sensitivity ingredients.

 SportDogFood Elite Food ($1.9/lb)15. SportDogFood Elite Food ($1.9/lb) – final contender on the list for best hypoallergenic dog food brand is a fairly new company SportDogFood with their Elite formula for advanced allergic reactions in dogs, and contains no grains as well as eliminates most popular allergy causing ingredients for dogs with food sensitivities. On paper this hypoallergenic formula looks good but many pet owners have reported allergic reactions nonetheless.
