i am from Brisbane and have brecently pucrhased a 13 month old lab x kelpie, named Pedro. i have only had him for two days. the first day i left him alone in the backyard, i received a call from my neighbour telling me he had got into his backyard. i drove home and discovered a gap in the back fence, which i blocked up. On treturning home that afternoon, Pedro was nowhere to be seen in my backyard. Again, i found him in the neighbours yard. I checked the area i had earlier blocked, and there is no way he could have got through there. So my question is, as a new lab owner, how can i teach him that any back yard, other than ours, is off limits??
thanks in advance
