Uni, you may have more luck with a Boxer than I do. I tend to spoil my dogs terribly and don't really train them as I should. I DO try to get Brutus to be calmer because of my granddaughter, but he knows I'm a soft touch and doesn't listen to me as well as he does my husband. Thing is, my husband is gone alot when Skylan is here (he works long hours). Boxers ARE a somewhat hyper breed, very playful, and to them ,everything is a big game, and when I do try to make him behave, he takes it all as a big game. Someone else might have better luck at making one mind, but they do tend to be a bit bull headed. Good luck with whatever you choose to do!
