My girl Poshy has had a hurt leg for about 2-3 weeks. At first I thought it was Marek's cause of the way she was walking, but after a week the other leg still hadn't progressed I figured it was an injury and would go away after a week. Her leg is still not doing any better than it was the first day she was hurt. She has started walking differently than she was at first. At first she was walking on the hock of the one leg, now she is like pulling it up in an arch. It hasn't gotten any better, is it just a slow healing injury? Could it be something else? What can I do to help her? I have had her in a dog crate outside during the day where they can still see her, then I bring her in at night. Here's a video of her:
