hi i have a lad mix that is over weight i took her to the vet and she is doing really good she has lost weight but she started limping after a walk that we took so i did not want her limp to get any worse so i let her take a break from the walks for a bit and it got better but know he is limping and she has not been on a walk so i think my bigger dog was trying to play alittle to rough and may have made her limp but im not sure so what can i do for her and her leg to make it fill better. thanks
