If I am going to switch dog foods due to suspected food allergy, should I switch the whole brand or keep the same brand & switch just the protein?

You're doing the right thing by asking about your dog's diet, especially if you suspect a food allergy. Dogs can develop allergies to specific proteins rather than the entire brand of food. If the brand you’re using offers a different protein source, switching to that might be a good starting point. For example, if the current food contains chicken, try switching to one with lamb or fish.



It's important to transition gradually. Start by mixing a small amount of the new food with the old food, gradually increasing the new food over a week to avoid digestive upset. If your dog's symptoms improve, the protein switch may have done the trick. However, sometimes additives or grains in a dog food can also cause allergies, so if the protein switch doesn't work, consider trying a different brand that offers limited ingredient recipes to pinpoint the allergen.



Watch out for signs of a serious allergy, such as persistent vomiting or diarrhea, itching, swelling, or severe lethargy. If these occur, contact a vet immediately.
