I too agree, having a 6 month old puppy myself....she doesnt go very far unattended, even in the house, as shes not totally housebroken yet-little brat, and outside we keep a close eye on both the dogs even though we have a fenced in yard...when colby was just a pup, he got out ONE time and that was all it took to practically give me a heart attack, so now we are extra cautious...cammie still stays in her crate when we are gone and Colby goes back and forth between having freedom and when he mis-behaves and chews and makes a mess while we are gone, he gets confined to the kitchen again...its been a battle with him all along, and hes 1.5 years old now...we werent giving him any free reign of the rest of the house other than the whole kitchen before cammie came along, but we thought maybe he had earned it...but give my bubbie a little freedom and he manages to screw it up
so hes back in the kitchen at the present....although, jamies mom is home most days all day and never says that they bark all day or seem generally upset at being left somewhat limited on the good life of laying around on the couch....good luck to you...
