We adoped Samantha just recently. She was an abused stray. She has a severly deformed leg. Rescue came upon her a very long time ago when they found some pups under a bush. They tried to catch her but she was too fast for them (some were University of Washington athletes). A year later they were finally able to. This time she was pregnant with eleven pups. She gave birth one hour afterward. A deformed leg really doesn't seem to bother them. Don't rush to surgery. Samantha gets around pretty good. I'll probably start her on Glucosomine soon to hold off the onset of arthritis.
