my gf and i have a jack russel, beagel mix. (i think) and i was wondering how i can get her to use the bathroom out on the balcony. we havnt moved in yet. where shes at now she has a backyard with free roam of inside and out. what i was thinking was a sliding glass doggie door w/a home built box with grass in it outside on the balcony. but if there is somthing that would cost less and not so much effert i would appreciate it.. thanx..
