I have 3 little long haired chuhuahuas, and I don't have to walk them at all. In fact, I just sit a bowl of water and food in the kitchen, lay some old pillows/dog blankets around the house in nearly every room, and they are fine. They stand by the door when they want to go "outside", then come back in and go sleep some more or want you to hold them. And 99% of the time they never take a leak or cr@p in the house, unless they are sick or weren't let "outside" for a long period of time....they have learned to hold it too, if we can't let them out right away.
