Lord, I sure hope nobody ever tries to break into this house while I'm home alone. Whenever my puppies hear a noise outside and start barking or wandering around looking, I just kick them out for ten minutes or so. Figure if it's nothing, then they get walked. If it is a person or critter in the yard, they won't be there for very long.
Don't know why I never really thought about that before. I suppose it's because walking the dogs is such a common thing that you don't really pay attention after a while? But it is kind of impressive watching 250+ lbs of bulldog launch themselves off of the back steps at full gallop.
