I leave my two big dogs outside when I am gone. They don't have a problem with it at all. They play all day long. I leave different toys out each day so that they don't get bored. We have a 15ft trampoline out back that they jump on too, its funny. My little pom stays in the house, he can only play with the big dogs when I am around. I confine him to the kitchen while I am work. The cats play games of chase with him, so I am sure he's entertained too.
