Easiest dog I have ever owned

My Greyhound is my fourth dog and by far the easiest. He does not chew, does not bark, does not require extensive grooming, and is happy with two walks a day. He is clean, quiet, and gentle. He has had zero accidents in the house from the first week. The prey drive around cats requires management but apart from that he requires very little. For a busy person who still wants canine companionship he is perfect.
