Sassy and Waldo are good dogs about to be let loose on their first class trip!

Sassy and Waldo love trips!When they put on their trench coat, everyone thinks they're a human kid named Salty.They can go to all the places that don't let dogs in. Like school. And the museum.Stewart says the museum is all facts and learning. He is not excited to go there.But Sassy and Waldo have a permission slip that says lunch on it.How can a trip to a place with lunch be bad?Sassy and Waldo are very excited for their class trip.And that's before they find out about the giant bones.
