My friend, a devoted dog lover and owner, lives in a tiny little house, with a very tiny garden. She walks her dog at least twice a day, every day. Her next door neighbour lives in the same size house, with the same size garden. She has a greyhound and 2 Jack Russell terriers. She works long hours, often out of the house for 12 hours straight, and the digs are just let out into the garden to do their business and then straight back in. They are never taken out to exercise. But when they escape, which is often, they jump up at people, charge at other dogs and run into the roads causing traffic chaos. Every one blames "those damned dogs." It isn't the dogs fault. They're bored, they have no stimulation, no exercise and no human company for most of their lives. A badly behaved dog is a direct result of a bad owner. It's them you should be tackling.
