This makes sense for Taggarts issue. But my brother got two puppies the exact same weekend that my mom got Little Bit. He doesn't potty at my brothers. Maybe because they are puppies and Little Bit is an adult (approx. 3 years old)?

Anyway, there are some good suggestions here. I hope they can find a solution and quickly.
