They just get out and run, get into fights with other dogs, harass cats etc. Dog stuff. It really depends on the dog's temperament. There are dog's that are too scared to get out of their yard. If you've got a hunting breed it will probably get out and run. When we throw a garden party, the dog becomes less interested in going for a stroll, it would rather join the party. It's a fox terrier mixed breed. Very smart dog. You can fool it once, but then you have to get creative.
