Food sensitivities usually result in GI distubances such as vomiting and diarrhea.
Pruritus (itching) usually indicates environmental allergies. If the condition is severe or continues for 4 seasons/1 year without significant periods of relief, consider asking your vet for a referral to a dermatologist.
Don’t be fooled by mail-in saliva and hair tests, food sensitivities fluctuate and food allergies are rare.
