Q. Newfoundland Boston sleeping on the couch owner approaches and pets both from behind on hind quarters. Newfoundland turns growls and bites arm.wcwd?
DR. JENNIFER LADD, DVM
A. Usually, in addition to be startled, there is an underlying reason for such behavior. I would be concerned that your dogs has some pain. Given the breed of your dog, I would recommend radiographs of the pelvis. When dogs are painful, from conditions like this or arthritis or otherwise, they can become irritable. Just like in humans .
A. It is never wise to approach a sleeping pet from behind and touch it. Always make your presence known to avoid startling your pet which can (and did) result in a bite.
