My dog has recently developed an extreme sensitivity on her lower back when pet. We went to the vet and her X-rays came back fine and her blood work came back fine. She was checked for fleas and that was fine, and no irritation on her skin. We recently doggy-sit my fiances moms dog- who is also a yorkie. He is fixed and she is spayed. My fiances mom is claiming that her new sensitivity could have been due to sexual activity between the two dogs. Is this possible? Her sensitivity doesn't seem to be causing her pain and she enjoys being rubbed on her back. Her head goes up, her tongue licks the air, and her legs seem to twitch in excitement. She has also been running her back underneath the chair legs and licking/biting near her hind
Legs. My vet seems to think there is nothing wrong with her behavior. Please help!
