I adopted Katie about two years ago. From a breeder rescue. She was then 8-9 years old and had recently been spayed and had some mammary tumors removed. Since then she has had regular vaccines and had her teeth cleaned with 9 removed. She is having a terrible time walking. We thought maybe her paws were too hairy so we carefully trimmed the hair away from the pads...that was not it. It seemed that while walking her front feet sometimes do not come all the way forward from the ankles and she stumbles. That was a couple of weeks ago and now I am noticing that she has trouble keeping her rear legs under her on the tile or wood floor. Does better on the rugs but when on the tile when the legs go out from under her she just sits there for the longest time until I pick her up and take her to a rug. I am really worried about this little blind dog with the over active kidneys (really, not just me, it is some genetic thing). A vet appointment will be made tomorrow but wondering if anyone has any ideas?
