I understand. My dogs don't get access to the front yard for the same reason: I want to supervise their interaction with people or other dogs, even through the fence. The back yard (approx 1000 mp) is fully secluded, no neighbors on one side and an empty paddock in the back. It's not visible from the street and the only access point is though the house. From my pov, the perfect playground for my dogs, with access to half of the house as well so they can get back inside and eat/drink/sleep or whatever. I never expected them to break the iron panels, though. They're much more sturdy than the main entry door, for example... so I wonder what they
can not break when I'm not home, then... (if they really want!)
