Other Conditions That Can Cause Your Dog's Itching
Allergies are not the only reason that dogs itch. In fact, to properly diagnose hypersensitivity, one of the first things a veterinarian needs to do is to rule out other potential causes of itching. Allergies are a diagnosis of exclusion, says Donna Spector, DVM, DACVIM, an internal medicine specialist with a consulting practice in Deerfield, Illinois. A dogs medical history can sometimes help his vet identify the reason for the dogs itching, but in other cases, the history may be lacking (such as with a shelter dog).
