answer:A belated welcome to Fluther! All I can tell you is that several of our dogs did the same thing, especially when Dad came home from a trip. Dad and the dog would end up on the floor and the dog would whimper as if carrying on their end of the conversation while he stroked and talked to it. My guess is if the dog stays in position while being petted, it is a way of communication. If it were in pain, it would back away or run off.
