My neighbor and I went for a long ride yesterday and her horse was limping. She said that she only limps when she has a saddle on her. She has had her seen by the vet and xrayed and everything came back normal. She seems to think the horse is "faking", but I don't think horses are capable of manipulation like that. (maybe I am wrong) I think something is causing her to limp. By the end of the ride it was very noticeable and seemed worse. Any ideas? She had her shod about 2 months ago for the first time (she had great hard feet but seemed to think she needed shoes) but she was doing this before the shoes.
