I have just returned from taking "crazy dog" to the vet. The vet.'s says that there is nothing physically wrong with the dog, but that he is having "psychological problems." The vet. is not sure what might have triggered the behavior, which has been going on for about 3 days. We have not had any major upsets in our home life. We added a "new" dog to our pack about 4 months ago. It is this dog that "crazy dog" is going after. The "new dog" just gets on his back, submissive posture, but "crazy dog" won't let him up for ages. After I took "crazy dog" home from the vet.'s I tied him in the yard just to give the other dog a break from getting beat up. Now, what about the peeing in the car behavior? The vet. said that there could be a variety of causes. He really didn't give me any ideas about how to adjust the canine relationships in our pack, or how to prevent the peeing and other hysteria in the vehcile. Any ideas will be most welcome.
