Molly's knee

Strange that she won't use Buddy's stool or is she unwilling to use it because it is his. I wonder why she is scared of it. What you need is a ramp. They make folding ramps that can be moved. If you could see one you could make it yourself.

It seems that you are not the only one with a dog who has mobility issues.
