There's a Dog in our House

and Henry loves this dog.
So much that when she is wet from going out in the rain, he will find a kitchen towel to go dry her off.
So much that he will lick her back when she licks him.
So much that he will climb on her back and try to ride her.
So much that he laughs hysterically and tries to cuddle with her on her bed.

I just don't get it.
