Hello, I have 2 mastiff/sheppard/lab mix 10 month old puppies (both sisters) and they found a way to get out of the yard during the day. We have replaced the whole yard fence and took any "assisting" shrubs that might have helped them jump over the fence. The neighbors were cool about it but I think they are getting tired of bringing Emma and August back into our yard everday. We have locked the doggy door in the garage so they are stuck in the garage but they are chewing the doggy door now. So we have placed a heavy metal table against the doggy door. We are thinking of new solutions so the dogs can be in their backyard unattended. They are great dogs inside but become mischevious when they're outside when no one is home. We are thinking about adding an electric fence on top of the fence. Emma and August are "huddle jumpers" they hop into every yard, scare little kids, eat plants, etc. I dont want them to be kennelled up! Help!!! thank you!
