I'm a little worried about my puppy injuring herself on my wood floors. My Ridgeback slips and slides like Bambi on the ice, and I know that growing pups can be prone to injury. Should I be thinking about some kind of boots for her? Or is that silly? Also, what about stairs? I read on a mastiff blog somewhere that you shouldn't let a puppy climb more than 3 stairs in a row...we have two stories, and I'd hate to force her to stay downstairs for years. I want her to be able to sleep in our room, but I won't be able to carry her for long/
