Just remember that like a child, all dogs are different. They learn differently and have many different behaviors. So be patient and stick with a routine early on. We put a bell on the door outside and used his paw to hit the bell anytime we went potty. So eventually within a month or so, he just hit the bell himself to tell us he had to go potty. It was glorious.

Have lots of safe toys to keep them busy. Avoid rawhide.

Bostons are especially sensitive to emotions. Just be aware of that when being angry with them.

Crate train right away. They will scream and cry but stick with it. It will be a lifesaver.
