So for the past month Chase has been walking carefully on his back left leg. He did fall a few days before, and I am thinking this is the result. But its been a month. Dreading going to the vet, but if he can't get relief we have no choice. Im scared its his CCL or ACL. But after feeling around, massaging and doing research, i dont think it is. He gets uncomfortable when I press gently right above his paw pads. I have inspected his paw and between his toes and nails, but nothing. Any suggestions?
