Lucy has been deteriorating in this respect for some time. When I mentioned it to her Vet last, he didn't comment and I neglected to followup. She has been getting progressively worse for about a year. The onset was a difficulty sitting still. when sitting, her front feet would slowly slide out in front of her. Then she began having trouble moving quickly on the tile floors. Her back legs would slide out from under her and she would go down on her hips. Lately she has trouble getting up off her bed when her front feet are on the tile. She has either become incontinent, or just can't get up to go, so she soils her bed every day or so. She works at lying down, making several starts at it before actually getting down and getting comfortable. However once she is up, and outside on the rough sidewalk or in the yard she pulls like a horse. At first I thought she was losing muscle tone in her legs/shoulders/hips, but it seems unlkely given her strength on rough surfaces. What are the possible causes of this?
