Bentley has taken to wagging his tail, though usually it's seemingly for no reason- like he's just looking around and out of nowhere he wiggles his tail. It happens even when Jasper's busy doing something and I'm not bothering him, he does it on my lap occasionally, sometimes he has a treat when this occurs and sometimes he doesn't. He has no symptoms of pain or illness and is a very playful happy boy who loves snuggling and scritches. Anger issues? Neurological? Has anyone had their baby wag for no apparent reason?
