Pooches: How Mr B Never Leaves his Tepee

This is Mr. B.
Mr. B lives in a tepee.
A tepee without a door.
Each day when we leave Mr. B is sitting in his tepee.
Each day when we return Mr. B is back in his tepee.
He must have been there all day!

Sometimes, when I'm coming home, I can look up and see Mr. B like this:

I will point and wave at him.
He will look back at me. But when I come upstairs, he is back in his tepee. Like he never moved.

Poor Mr. B. He thinks that we don't know he doesn't stay in his tepee all day.
