thanks so much for getting all this together! axle was diagnosed with HD when he was 6 months old, and got a lot better for a while, but unfortunately it's starting to show it's face again recently. like the one article said, it helped a lot when we moved from an all hardwood floor house to a carpeted house. steps still bother him a lot, and so does getting in and out the truck. we're debating on getting the little ramp, because axle is usually really nervous on any kind of ramps, so we've just been lifting him as often as we can, but that causes problems with our backs hurting! he's already on a special diet, and medicine for it, so if anyone comes across an alternative to the ramps, please post!
