Advice?!

I’m bringing my service dog prospect home on Tuesday, he is 6 months old.

He has only been trained to sit, come, and watch. He also is 99% potty trained too. He open feeds so I was told to always leave food in his bowl and he will eat when he is hungry, same with water.

He has a good temperament, he isn’t too hyper but is still very active and driven. he doesn’t jump, he doesn’t really show attention to people unless they try to get his attention.

He loves cut up hot dogs as treats apparently.

He is NOT crate trained

What are some basic commands and things I should teach him?
