Our 6mth puppy just been diagnosed with moderate HD both legs. At moment just meant to manage - careful exercise , hydrotherapy, supplements. Am thinking is it not better for him to have an op once bones mature, rather than spend his youth with him unable to do stuff he wants to do and then only have op when virtually immobile, old and likely to take longer to recover? Do hip ops mean that they are more mobile than before? At mo he is able to move OK but any thing takes it out of him. Today he was walking about like an old man. Breaks my heart.
