Thanks, He does do the "bunny hop" thing with his hind legs when he really gets running around. He's always done it since we adopted him almost a year ago, and at first thout it was a funny way to run, but never knew it was a symptom of HD, untill i started doing some research. Another symptom i notcied is that he has been carrying his tail down alot lately where he usually carries it up on top of his back. Something else i didnt even think about, He used to pounce on the bed when he would get up with me, but the past 2 or 3 weeks, he's been doing this thing where he tries to crawl up on the bed, and i have to help him up. I thought he was just being a goofball, but now i'm thinking that he was having pain from jumping up onto the bed.
