Val, I was just looking at the latest video. If you compare it to the very first one you posted, the difference is amazing. You can see how much more confident/comfortable Babybear is with his wheels. I wonder, if after a certain amount of time, it would ever enable him to walk without crossing over his front legs? Would those muscles and their co-ordination strengthen over time as they become stronger and more mobile?
The other day you asked about booties for him when the weather turns very cold. Do you think they would effect/hinder his "feel" for the ground? I wish there was a large indoor area that you could take him to. Are there any schools in your area, that would allow you to use their gymnasium after hours? Or, perhaps your local PetsMart? You could take him there in bad weather to stroll the aisles.
Hugs to you and your little bear,
Lauren
