wow, 3 hours a day?? i am the only one who walks him so it's a little difficult to do even 2-3 hours. my husband's idea of walking the dog is down the street and back
also there's not many places we can take long walk in my neighborhood, it's the same old boring route. he seems to be ok, doesn't get into too much mischief. but maybe 40 mins a day may not cut it?? i take him to the park once or twice a week and we do play fetch and hide and seek in the house.
i'm big on the mental stimulation bic i do feel he may get bored easily.
