BJ's dog Troy was here for about 40 hours, much to Maisie's delight. Troy runs and runs and runs, always looking UP.

Troy must be a bird dog. He'll run looking up, then stop and look up, and go off again running. I feel like he's always saying in his mind,
"Bird? Bird? Bird! Bird!"
Imagining that Troy is thinking mostly about catching a bird (or a squirrel) reminded me of the wonderful children's book
Barney Bipple's Magic Dandelions by Carol Chapman and illustrated by Steven Kellogg, which unfortunately may not be readily available for purchase. Barney's book has his dog voicing his canine thoughts!

Barney is given three magic dandelions by this amazingly eccentric woman named Miss Minerva Merkle. He wishes to be eight years old like his big brother; he wants his dog Snoozer to talk; and wishes for a big, shiny car to drive. The funniest part is about his dog's thoughts:
Barney asks him, "Wouldn't you like to tell me about some adventures?"
"What adventures? All I do is eat and sleep. I did have an interesting dream about a steak once," said Snoozer.
Steven Kellogg's illustrations have images of Snoozer's thoughts that go like this:
eat, sleep, eat, sleep, eat, sleep, eat, sleep, eat, sleep, eat, sleep. . . . . That's what I remembered when I imagined Troy's chasing thoughts. When I reminded both BJ and MJ of the book about Barney Bipple, they both remembered it!
In contrast, I think Maisie's thinking might be more sophisticated in that she skitters among many topics:
eating, drinking, chewing, running, playing, chewing, sleeping, on the couch when no one is around (to be repeated over and over again).
Maisie sneaks up here, which is supposedly not allowed. But our kids let their animals on the furniture more than we do so Maisie has gotten used to doing that, especially with MJ.
