What famous person is your pet most like?

[Vincent, Thunder God]

I have no clue my dog's personality has changed some ever since he started biting his tail. Before then he was all jittery, and playful, now he just sits in front of the trashcan all day, until I take him outside. I wonder what's wrong and he continues to bite himself, making him bleed. I have a zu.

Edit: what's with the skulls messing up my post?

First of all, I would suggest taking your dog to the vet. It sounds like something is bothering him. Often when a dog starts randomly acting in a strange way it means that he is sick. I know my dog has acted in a subdued, even sad way in the past, and we've had to take her to the vet, who found the problem and helped her get better.

So you should probably get a veterinarian to check your dog right away; if he's biting himself maybe he's itchy from fleas or something else. Or maybe he's not getting enough food? You'll notice that as soon as he's healthier he'll behave better again. I hope your dog gets better soon.

As for the skulls, it's because the swear filter took away the "sh*t" from "sh*tzu."
