Our terrier got into the chicken yard and grabbed a 20 week old pullet. She was fine except for a foot that seems to be injured. There were no tears or blood but now two days later she hops around and holds the foot up. My husband picked her up and said she seems to have no broken bones but she sure does not put weight on it. Today she seems to hold it up as if it isn't even there so that it hangs down. Should it be splinted? We thought that after a couple of days she would walk on it. Ideas? Thanks!
