How about a walk? My hubby walks Mia for at least a mile - every day. If he didn't - I think she'd be doing it to him. Plus we do have to set aside time to play with her. It's just like having a child. If you can't walk them, maybe you could pay someone you know to do it. There's an elderly lady that walks her dog the same time hubby does and she walks her neighbors Yorkie for at the same time. Just an idea...
