My staffy Leo gets walked for 1/2-1hr every day.... Depending on whos walking and how much playtime he has had, most days my OH walks him for 1/2hr and then does play time for 1hr, but if he is late home he goes straight into play time and i walk Leo for an hour when i get home. (I dont know what that is in KM though. )
As he is getting a bit older now (nearly 11 months) i have been taking him for longer walks on the weekend 1 1/2hrs or so but he is still full of energy when we get home and wanting to play with his toys or play soccer (after 1 1/2hrs of walking!) Im lying on the couch exhusted and he keeps bringing me his toys like come on! Crazy dog!
