All day yesterday Oscar's talk was curled back instead of up straight. Even when I pet it straight he pulled it back curled. He was still trying to wag it, but it still seam weird. He doesn't seem to be in any pain, but he doesn't really like us to bother his tail. I am thinking maybe he got it slammed in a door or something and it is bruised? Could it be a problem with his back, maybe he hurt it or something? Thanks for any suggestions...here is a picture. If it isn't better by Monday we are going to take him to the vet. But today it already seems a lot better.
