Looking to get a training collar for a small dog. Hes pretty well trained for a house dog but he has a "friend" across the street now and hes off like a shot across the street anytime the kids open the door now. Going across to texas this month so thought it would be a good time to get a collar and save myself some cash. Don't want any high dollar stuff as it will just be wasted but I don't want something that has only the range of the front garden! Any ideas guys?
