I have a Cayuga that was pinned down by a playful puppy, I feared the worst when she wouldn't walk. The next day she limped around and could get to the food and water by her self. She appeared to be getting much better over the next couple weeks. But then yesterday and today she can hardly walk, she has kind of a limp necknow, and is much smaller than the other four. Is it too late to save her or am I screwed?
