I hasve a very active 7 month old Shep/Chow and even the walks are not enough I take about an hour severasl times a day and have time w/him working from home makes it that way at times it is not easy. When we started that he was chewing all the time I got some hooves and he loves them to the poing he knows when it's our time and he will bring it to me where ever I am, correct and direct is the way to go .. if he has toys use them as well
