Here's a helpful site, or at least it was a few years ago, thats about the last time I really looked around. It was very helpful for me when I needed it.

Gosh, there was a community/forum that I used to a member of for years, it was strictly about anything that had to do with mobility issues in dogs. I lost the link when we had some computer work done a few months ago. I've been searching all day & can't seem to find it. When I do I'll post it, that site was my best friend during many hard time with both Raustyk & Nanook as well as a few fosters.
