A friend of mine has an awesome Saanen buck as well as an Alpine doe, together for 2+ years and not a kid to show for it. He "walks" on his knees and has since he was 8 months old, now he is "stepping high" and throws his front feet forward. He has really gotten worse and foot trims are really difficult because he has really odd hooves. I know I should research this but right now I know there are ALOT of you who can give me input...his knees are swollen but I'm not sure if it's from him walking on them...he looks bad when doing thistoo, you can tell that it hurts him to get around with his tail high in the air. If it's not CAE what causes this to happen?
