Aren't dogs funny with their little quirks! Our RB Border collie would feign a limp when she felt she wasn't getting enouh attention (which was all the time ). As soon as we'd throw a "pity party" for her and her 'sore leg, she'd be all better instantly lol! She was wayyyy too smart for her own good, and I miss her terribly even after 10 years. One of the best finds I ever rescued...along with her six female newborn pups.
