In people, food allergy symptoms usually include a tingly sensation and a itching of the throat.

If your pet shows any of these symptoms, it’s a good time to reevaluate what you’re feeding. After all, May is Food Allergy Action month. Your veterinarian can run tests on your pet but it can be tough to pinpoint the exact allergy triggers simply because allergies develop over time.
