Don't be blue . Are you crate training your puppy? Any accidents in the apartment when you aren't home?

It sounds like your puppy isn't sure you are the boss yet. Adding stress with your boyfriend to puppy stress can make things very difficult, I'd look into obedience classes right away. The tips here at Pet Talk are great for learning how to relate to your dog but training is still difficult and it sounds like you need extra help.

Don't worry, the puppy stage isn't forever but the better you train your dog now the better the future will be!
