Al's Dog is Hurt? Help please :(
Al's dog went to the groomer 2 days ago. And when he came back, Al noticed that besides the usual tail biting he does, he has been having some leg issues.He's been walking while leaning to his right, and when he stands normally, his right leg tends to stick out, like this:

And then as he walks, he kinda lets his right leg stick out a little bit more, and he curls his body as seen here:

The entire time we walk, he curls himself, and walks akwardly. Sometimes he sits down as we walk. And at home, he gets agitated if someone rubs his right leg, but is fine if its the other one.
I'm hoping nothing serious is going on because if something happened at the groomer's, we don't have any proof. :(
Please help!
