The video was taken the morning of Wynona's dual stifle surgery. She normally would lock up a lot worse, but I think the humidity and the cooler temperature was allowing her to walk somewhat normal. Often times when walking, one leg would severely lock up and would swing out more to the side. Think of it as a person having a bad knee, and their leg is completely locked up. To walk, the person would need to swing their leg out to the side.
