I have an appt. with the vet tomorrow but am wondering if someone has a clue why my dog is limping. He and the new puppy were playing and I didn't see what happened exactly. Just know the bigger, older dog was limping on his back leg. Not quite able to put a lot of weight on the leg and kind of walking on his toes instead of putting the entire foot down. I put him on pain meds and anti inflammatory meds till I could get him to the vet and I notice the foot is now more flat, but he's still limping. I know it's not broken and he doesn't act like he's in pain when at rest, just has the limp. the leg appears to kind of stay straight and goes back stiff like. He bends it too wee wee, walkd up and down stairs OK. Any thoughts?
