Yes, a dog is a big investment of time. I agree that a lot of people don't understand that. But the investment is worth it.
He is a puppy still, and he is going to chew. He is very well supplied with chew toys, including rawhide. He had a ball that he could barely get his mouth around, so I got him a couple of smaller ones with squeekers in them, and he struts around squeezing his toy, happy as can be. If I try to play fetch with him he gets the ball and then wants to play hide and seek.
His owner is 13, and a very responsible kid. But he's in school most of the day.
