It's a very hot day at Pup School, so Miss Collie lets the pups set up and play in the paddling pool.

The pups hear about a song contest on the radio and decide to enter. Dodge, Woofer and Puggers want to form a band, but can they write a song that's good enough to win it?

Dodge creates a den club for all the pups. They need many rules to keep everything and everyone in order.
