my thoroughbred mare has been limping the past two weeks. i called the vet and she came out and said she has hock arthritis and the bones needs to fuse. i really wish to compete in english showing or dressage. my vet was unsure if she would be able to do that. how long does fusing usually take? my vet told me to keep riding her. i dont know if i should sell her or not. i no she could be a great broodmare and produce lovely babies. while i am debating on selling her, is there any therapeutic exercises that would help keep her comfortable and begin the fusing process??? she is only 11 yrs old and she is my first horse. i would hate to sell her but i also can not afford to give her special medicine constantly. HELP
