Expert Answers: FAQs on Dog Food for Allergies
We asked Dr. Stephanie Liff to answer the most common questions dog owners have about allergies.
FAQ
Food allergies in dogs can show up in a few different ways. You might notice your dog scratching more than usual, having a dull or patchy coat, or dealing with digestive issues like diarrhea, vomiting, or trouble keeping weight on. If your dog has a poor appetite or just doesn’t seem like themselves, that could be another sign. Pinpointing the exact allergen usually involves switching to a limited-ingredient or novel protein diet—something your dog hasn’t eaten before—and monitoring for improvement. It’s best to work with your vet to guide this process.
If your dog is dealing with food allergies, it's wise to steer clear of common triggers like beef, chicken, and sometimes fish—especially since these proteins show up in a lot of dog foods. While every dog is different, avoiding ingredients that commonly cause reactions is a good starting point. Transitioning to a food with a single, unfamiliar protein can help you narrow down what's causing the issue.
For dogs with suspected food allergies, novel proteins are often the best bet. These are meats your dog hasn’t had before, which means their immune system is less likely to react. Options like venison, rabbit, duck, salmon, or white fish are commonly recommended. Your vet may suggest starting with one of these to see how your dog responds.
Once you’ve removed the allergen from your dog’s diet, you might start to see signs of improvement in a few weeks—but it often takes 6 to 8 weeks for full results. During that time, it’s important to avoid feeding treats, table scraps, or other foods that could contain the allergen. Stick to the new diet consistently so your dog’s body has time to heal.
Food allergies usually cause things like itchy skin or ear infections, while sensitivities might just cause an upset stomach. Both can be helped by picking the right kind of dog food—just takes a little trial and error sometimes.
Chicken is one of the most common protein allergens in dogs. While it’s perfectly fine for many dogs, those with food sensitivities might react poorly to it. If your dog is showing signs of a food allergy, it’s a good idea to avoid chicken until you know more. Choosing a dog food with a different, novel protein can help you figure out whether chicken is part of the problem.
