Kito loves to sit out on our patio and stare at nothing, while he is sniffing the air. Abbey prefers to sit out there and bark at nothing, while sniffing the air also I have to watch them, because it is a second story balcony, but they really enjoy being out there and just sitting sometimes. I think as long as he is not bugging any neighbors with the barking, let him go out there when he wants too--just not all the time!!!!
