Doggystyle: Update on Mr. B's Teepee

Back in July, we took a gamble on replacing Mr. B's traditional crate with a teepee. While we wouldn't recommend it for most dogs, we decided to make the switch because we never shut the crate on Mr. B's door anyway. He was merely using it for denning purposes, and we thought a teepee would be a funny, stylish upgrade.
Mr. B. took to his teepee immediately. We decided to get some dog-resistant FLOR carpet tiles because he was having some issues with his bed sliding around on the hardwood floor.
We did have 2 instances where he actually did knock the teepee over. When he heard us coming home he rushed back to pretend he had been sitting in his bed the whole time.
Here he is, feigning innocence, and pretending he is sitting in a teepee:
While Miss M was initially scared of the teepee, she has finally understood that as a new item brought into the house she must claim it. She is often found sleeping here.
