Chicken-Free Treats for Dogs with a Chicken Allergy: What to Look For

This article is for general information only. It is not veterinary or medical advice, and it isn't a substitute for an exam or diagnosis from a veterinarian. If you think your dog has a food allergy, talk to your vet before changing their food or treats.

Chicken is one of the most common food allergens in dogs, along with beef, dairy, wheat, and lamb [1]. 

The only reliable way to prove a food allergy is a strict elimination diet trial followed by a controlled food challenge [1], and that process should be guided by your vet. This article explains what the research says and what to look for in a treat, so you can have a better-informed conversation with your veterinarian.

How common chicken allergy is, and what it looks like

Chicken is a common culprit, but not the most common. A 2016 review of published studies looked at 297 dogs with confirmed food reactions. Beef was involved in 34% of cases, dairy in 17%, chicken in 15%, wheat in 13%, and lamb in 5% [2]. Some dogs react to more than one food [1].

Food allergy itself is less common than many people think. About 1% to 2% of dogs seen by vets have some form of food allergy. The share rises among dogs with itchy skin, where studies report 9% to 40% [1].

The signs vary. Itching is the most common skin sign, often on the ears, feet, and belly. Dogs may also have recurring ear infections or skin infections. Some have digestive signs like vomiting, diarrhea, gas, or more frequent bowel movements [1]. Food allergy signs are usually year-round rather than seasonal [1]. Many of these signs overlap with environmental allergies, flea allergy, and infections, which is why a vet exam matters before assuming it's the food.

How vets diagnose a food allergy

An elimination diet trial is the gold standard. Your vet will typically put your dog on a diet built around a protein they've never eaten before, or a hydrolyzed diet, where the proteins are broken into pieces too small for the immune system to easily recognize. The dog eats only that diet for the whole trial [1]. Trials take time: a review found that a minimum of 10 weeks may be needed to identify 95% of food-allergic dogs [1].

At-home and blood tests aren't reliable for this. Veterinary experts note that blood tests for food antibodies, hair analysis, and several other tests don't consistently give accurate results [1].

Treats can ruin a trial. If your dog is on a trial, give only treats your vet has approved. Sometimes that means none at all, or pieces of the trial food itself. That includes rawhide chews, pill pockets, table food, flavored supplements, and flavored toys. Chewable flea and heartworm medications often contain beef, pork, or soy protein, even when it isn't on the label [1].

The challenge confirms it. After the trial, your vet will usually reintroduce the old food. A food allergy is considered confirmed only if the dog improves on the trial diet and then flares up when the old food comes back [1]. That's how you learn whether chicken is really the problem.

What to look for in a chicken-free treat

Read the whole ingredient list, not the front of the bag. A treat sold as "salmon" or "beef" can still contain chicken further down the list. Chicken can appear under several names, such as chicken meal, chicken broth, chicken liver, or simply "poultry." If you're not sure whether an ingredient matters for your dog, ask your vet.

Fewer ingredients means fewer unknowns. A single-ingredient treat makes it much easier to know exactly what your dog is eating, and to spot a pattern if symptoms come back.

Know that labels aren't perfect. In a 2018 analysis, unlisted ingredients turned up in a median of 45% of tested foods, and in 33% to 83% of foods marketed with "novel" or "limited" ingredients [3]. Although it's unclear whether these trace contaminants cause reactions in allergic pets [3], it's a good reason to choose brands that are open about how and where their products are made.

Ask about shared equipment. Ask treat companies whether its products are made on lines that also process chicken. A transparent company should be able to answer.

Treat options to discuss with your vet

There's no single "best" treat for every dog with a chicken allergy. The right choice depends on what your dog has eaten before and what your vet finds. These are the main categories worth asking about.

Single-protein treats from a protein your dog tolerates. For many dogs, a treat made from one protein other than chicken works well. Keep in mind that related proteins can sometimes cross-react. Some experimental evidence suggests cross-reactivity between chicken, whitefish, and salmon, though how much that matters in real dogs isn't yet clear [1]. That's one more reason to check with your vet before assuming any protein is safe, including fish.

Hydrolyzed treats. Hydrolyzed products break proteins into tiny fragments that the immune system has a harder time reacting to. Extensively hydrolyzed diets are less likely to trigger reactions, even in dogs sensitized to the source protein [1]. In the 2018 labeling review, hydrolyzed pet foods were also the least likely to contain unlisted ingredients [3]. Hydrolyzed treats are usually available through your vet.

Pieces of your dog's prescribed diet. If your dog is on a therapeutic or elimination diet, your vet may suggest using kibble or pieces of that same food as treats, so nothing new is introduced.

Some fruits and vegetables. Veterinary nutritionists list options like carrots, green beans, apple, and watermelon as low-calorie treats for many dogs. They also warn against foods that are harmful to dogs, including grapes, raisins, onions, garlic, chocolate, and macadamia nuts [4]. Even safe produce counts as a new food, so check with your vet first during an elimination trial.

Whatever you choose, introduce one new treat at a time. Food reactions can take up to 10 to 14 days to show up, which is why, during a food challenge, vets typically introduce new foods no more often than every two weeks [1].

Where Wild Run fits

Our Wild Alaskan Salmon Snacks have one ingredient: wild Alaskan salmon. There's no chicken in the recipe, and no fillers, grains, or preservatives.

Please note that salmon isn't always the right choice for every dog with a chicken allergy, especially given the possible cross-reactivity between chicken and fish described above. We don't claim our treats prevent or treat allergies. If your dog has a diagnosed or suspected food allergy, please check with your vet before trying them, and if your vet gives the green light, we'd love for your pup to give them a try.
