Welcome to YT! Jobi is very cute and I wish you lots of luck with your new puppy. Sounds like you are off to a great start with potty training. As for trick training my Doodlebug was very small when he started to do tricks. My suggestion for training him would be to find a treat that he only gets for doing tricks and work at very short intervals. He's just a baby so his attention span is very limited. Dbug did quite a few tricks around 14 weeks old or so. Let me say that a little 2 lb puppy that can do tricks is a real show stopper. Make sure your treats are very tiny and yummy too. Good luck!
