Since O was the first puppy that my mom had, we really didn't know what to do. So, I love to google and that is exactly what we did. When she didn't start walking according to the puppy schedule...we found answers on the internet. The results told us what to use and how to hobble her. She really tried to walk on her own, but it was such a task for her. We don't know if having no litter mates was a culprit. She had no motivation to get up and move. So, by hobbling her, it allowed her to play. Her back legs were hobbled so they wouldn't splay past shoulder length. That made it so she could move around without human help. That video was the first day of her being hobbled. It didn't take long for her to learn those muscles. I'm glad we didn't wait any longer...she was already over a month old.
