When I fed my kids yesterday one was limping badly on a back leg, had a look and thought it was possibly in the hoof area, so trimmed and sprayed. This morning when I went to feed I couldn't believe it she was limping even worse on the other leg. It seems to be more in the thigh area that she is upset at moving. Do you think it could be a muscle strain from limping on the previous leg? She is obviously in abit of pain. Should the vet be called out today? I always think they feel I panic over anything.
