If your lab is hard to care for you probally need obediance classes they can help you and your lab. Some dog are just highstrung and are hard to care for if you don't have time for a dog like that you should prefer another breed. Labs also love swimming and walking. My labs has a bad habit of chasing machines and I walk him and that usually calms him down but he still has alot of energy and is very highstrung so what I do is I keep him on a leash and in a crate at night and when I'm gone but that probally doesn't help alot but I'm working on training him for agility and maybe that will calm him down.
