If a dog has a food allergy, its immune system overreacts to an ingredient (usually a protein like chicken, beef, dairy, or wheat), causing symptoms like intense itching, skin infections, ear infections, and gastrointestinal issues such as vomiting or diarrhea. These symptoms often appear after repeated exposure, and diagnosis involves a strict vet-supervised elimination diet to identify the culprit, which is then managed by avoiding the trigger ingredient, as food allergies aren't typically curable.
