Argo has a slight limp (sometimes) on right front leg. Touched foot, leg, shoulder, back and neck. Took him to vet and they couldn’t find anything wrong. He runs and plays fine but in the house he will sometime raise his leg and it seems like he walks on his tiptoes on that one leg. He can jump, run and play just fine. He’s very active and otherwise very healthy. He holds his head up and he’s very coordinated catching balls or frisbees. Anyone have experience with something like this?
