Frequent scratching, licking, biting, or rolling. Hair loss, scabby or inflamed skin Increased whining or screaming. Difficulty sleeping or unusual behavior. If in doubt, contact your veterinarian. If the allergy is confirmed, try to avoid any contact between your pet and the allergen. Then the last option is so-called immunotherapy.
