I often thought the same thing! The neighbors across the street keep their Rottie outside, roped (or chained) to a tree and the poor thing just barks his head off! He snarls when anyone passes, esp; with dogs, I never see the owners walk him. Even very late at night they leave him out, even when it drizzles (ok they take him in when it rains)Not only do I feel sorry for the dog but why have a protection dog if he's outside all the time? The only reason I don't call the Humane Society is that I know they will know it's me and I really don't want to start anything in our very nice, friendly neighborhood. It is a big issue. My Cody is outside alot, but usually with somebody. The interaction is inside, play is outside. I guess it depends on the dog and location. Just my thoughts, as well
