Bogey is almost 9 months old. We started about 1 1/2 months ago, putting his xpen attached to his crate with the door open. We did this when we went out for a couple of hours. This gave him a good area to get up and move about, yet small enough to contain him from "trouble." He has never had an accident in this area. Onto stage 2: took his crate away, and used the xpen to cordon off a fairly large area of our living room. He has a brand new bed and it is tucked into the corner where his crate was. Again, he has been fine with this freedom. For the last 2 weeks we have been leaving him for a couple of hours at a time with free range of our home, minus the bedrooms(doors are shut). At night, I stilluse the xpen to cordon off his corner of the living room. Eventually, we will take the xpen away. It really is different with each bully. bogey is not a chewer or destroyer of pillows or cushions, so he has earned some trust in that department. So far, so good with his housebreaking. He will get more freedom as he gets older. Good luck!!
