I have a little chihuahua, she is the greatest. I love her to pieces. She is an inside dog, of course. However, there are a couple of large dogs I am particularly interested in. One of these, is the Anatolian Shepherd. A beautiful dog, known for it's ability to guard livestock. They actually live with the chickens or whatever and protect them from predators. Keeping chickens is a real problem, because the predators come looking for them. This dog would keep them safe and I may buy one some day.
