Buyer’s Guide

Often it can be hard to distinguish whether an allergy is caused by food or environmental factors. So you need to pick out food that is safe from all kinds of additives and allergens.

Picking hypoallergenic foods for dogs can be tricky. You have to keep an eye out for multiple allergies and still ensure that all nutritional needs of your dog are met.

So what are some of the things you have to consider before buying foods for dogs with allergy issues? Here is what I consider important.

Most Common Food Allergies

Allergies mostly take place when your pooch’s immune system is unable to fight off the bacteria or allergen. When this happens, certain symptoms manifest.

According to experts, most common food allergens include:

  • Beef
  • dairy
  • egg
  • wheat
  • chicken
  • fish
  • soy
  • pork
  • lamb
  • rabbit

But these are only the most common ones and do not include allergies that your dog may have developed from their surroundings. It almost all cases, finding out what your dog is allergic to is a process of elimination.

Keep in mind that the more exposure your dog has to the substance they are allergic to, the worse their allergies will be. It is best to get them examined by a veterinarian so that you know for sure what element is working against them and how best to deal with the situation.

Food Allergy Symptoms

Even though individual dogs have individual symptoms for various kinds of allergies, some of the most common signs include:

  • Excessive itching
  • skin rash
  • dry or flaky skin
  • bald patches
  • hives
  • skin infection
  • biting paws
  • vomiting
  • diarrhea
  • chronic flatulence
  • itchy bottom
  • high occurrence of hot spots

How to Choose the Right Foods for Allergy prone Dogs

To choose food products that are beneficial to the health of your allergy-prone pooch, you need to keep a few things in mind. These are:

  • The age, breeds, reproductive status, and activity of your dog. If the dog is a puppy, an adult, or a lactating mother, then you will need to choose food that suits their nutritional needs. The more active dog you have, the higher the calorie content you will need.
  • Read the label of the commercial food product with care. What kinds of allergens are in here? What kinds of protein are used? Is the food grain-free? If not, then what grains are included? These factors will decide how well your dog takes to the new food.
  • Research the manufacturer of the food and then consult with your dog’s vet. They already know what foods work best with which kind of allergies.

If you follow your vet’s treatment plan, there is no reason not to expect a happy outcome for you and your dog. Focus on getting them the best nutrition possible within the limitations of their allergies.


Dog owners whose pets are allergic to environmental or food allergens are always on the lookout for information about their dog’s allergies and how best to treat them.

We’ve listed several frequently asked questions to help you make all the right food choices for your furry friends.

Common signs of allergies include itching, sneezing, itchy paws, hot spots, skin rashes, scaly or oily skin, pigmented skin, leathery skin texture, and of course, biting of the affected area. Because allergies can lead to other complications, it’s best to have your dog evaluated by your veterinarian.

Supplements that contain Omega-3 and Omega-6 fatty acids, along with oils like coconut oil. Opt for food formulas rich in these substances and also contain fish or other seafood sources.

Dogs do develop allergies to chicken, but it is not common for them to have allergies to chicken fat. Buying food that is free of chicken but does contain chicken fat should be safe for your dog.

What food is best if my dog is allergic to chicken?

In most cases, the go-to food would be lamb, as the proteins in lamb are less likely to present problems vs. chicken or beef. Other meats that you can try are fish, duck, and venison.

What are natural remedies for dogs with allergies?

Food has the power to heal and if you know that your dog has allergies you can give them oats, aloe vera, thyme, coconut oil, apple cider vinegar, mixed in their food. You can also opt for commercial foods that contain these items.

How to find out if my dog is allergic to certain food ingredients?

There are clear signs and symptoms of an allergy reaction in a dog. Food allergies often result in vomiting, flatulence, diarrhea, ear problems, sneezing, coughing, or even wheezing. You will only be able to discover which food by the process of elimination.

Why is dog itching so bad if he does not have fleas?

Even one flea bite can cause a reaction in dogs allergic to them, and fleas can be hard to see. Severe itching is a result of allergies, and if you have already eliminated food allergens, then your dog may have environmental allergies that come from their environment, like pollen or, yes, fleas.

Is lamb safe for dogs who have allergies?

Lamb is generally considered a safe pick for dogs with allergies to chicken or beef. You can also give your dog, fish, venison, or duck if they do not take well to protein sources obtained from chicken.

How to know if a dog is allergic to grains?

When a dog has grain allergies, they develop either gastrointestinal signs like diarrhea or vomiting or dermatological signs like rashes, severe itching, or chronic foot or ear infections.

Can dog allergies go away by eliminating a particular ingredient?

If your dog is suffering from an environmental allergy, then no. But if your dog is allergic to a particular ingredient in its food, then removing that ingredient should allow it to become allergy free. Finding which ingredient your dog is allergic to can only be found through a process of elimination.

How do I feed my protein allergic dog?

The best choice to make in this situation is to give your dog fish proteins. Turkey and duck proteins are also good choices for keeping allergies at bay while providing your dog with sufficient nutrients.

Can allergies be fatal for my dog?

In most cases, they are not, but there are instances where they can be. The problem with most allergies is that they can lead to other problems. For example, a dog that continuously bites at itchy skin can cause the skin to become inflamed and infected.
