I had my black lab at the pool over the weekend and he was having a grand old time running around. He showed no signs of pain, but when we got home he started to limp and now he can barely walk. The pads on 3/4 paws came off in places. Has anyone else had this happen to their dog? It's really terrible to watch him suffer like this let alone having to carry an 80 lb dog in and out of the house to poop and pee. I took him to the vet and they gave him some pain meds but didn't know if any of y'all might have some kind of effective home remedies.
