Increase exercise, walk the dog for 1 hour a day, play fetch for 20 minutes a couple of times a day. A tired dog is a well behaved dog. Swimming, running……

The dog may be teething, puppy proof your home as you would with a small child.

Otherwise, consider Roseanne’s advice in the above post. Have a serious talk with all in your household, dogs can be a lot of work.
In my experience they start to calm down around age 2.
