Bostons are often very energetic dogs. They do tend to get calmer with age, but making sure they have plenty of constructive outlets for their energy is always a good idea.
Our youngest, Chloe, is the very definition of high energy. Over the years, I've found that as long as we give her some time to get some good exercise she becomes a much more balanced dog. When I get home from work, the first 15-30 minutes of my time is spent playing frisbee with her and Duke.

As for the playful biting...When you play with Max, do you often use your hands to do so? Seems he might think of your hands as a toy. He may just be so full of unexpended energy and his outlet is to play at any opportunity.
