Hi I love my boxer (Harley) to death, but my wife does not feel the same way. She constantly is complaining that the dog is too hyper and is afraid of the dog trying to bite the kids. Harley is 6 months old now and is a good dog, she obeys when told to sit, down, paw. I try to walk her frequently and have occasionally taken her to the park to play. My wife's biggest complaint is that Harley will not just lay down or sit down while we watch tv as a family. I guess Harley may have too much energy, so what I am asking is what would be the best way to tire Harley out so that when it is time for us to watch tv she will be so tired that she will just lay there and not run around the house. And what recommendations are there for her bitting or nibbling on the kids. Please any help would be great, I really want my wife to love the dog.
