Buster has started to relax.
We couldn't get him to even look at that bed his first night here, now he spends his work day in it. Haven't heard him bark yet, but he did let out a growl when I walked into the house after coming in from running an errand. I got the knee breaking tail wag a second later, so he is taking on the roll of protector of Moms' house.
He stays off the furniture, which is not a rule in our house. He won't go into the kitchen, which will be a problem because the back door to where his run will be is accessed through the kitchen.
I've found that I will be walking more just taking him outside for his multiple daily pee breaks. We will need to spend some time on his leash manners. He hasn't popped my shoulder out of joint, yet, but at 60+ pounds, the possibility is there. So far, though, things are falling into place.
