I think my dog is sometimes masturbating by licking her vagina very passionately while making humping motions while she is in heat. Can a dog actually do this for pleasure to themselves (i.e. there is nothing wrong)?
All the threads I found said there may be a problem, but none of them mentioned that it can be merely an act of pleasure and no problem.
Is it possible it is merely a pleasurable act, not some vaginitis or whatever?
