Book excerpt: Holiday mischief abounds in this third book in the middle-grade series that feels like The Secret Life of Pets meets Toy Story. Are the Good Dogs up for a holiday-sized mission? All of the doggy day care friends are excited about the holidays! King, Cleo, and Napoleon can’t wait for their eight nights of Hanukkah prezzies, and Hugo, Waffles, and Lulu are ready for cozy Christmases at home. But then surprise visitors interrupt Lulu’s shooting schedule, Cleo struggles at an agility contest, and Hugo learns that Waffles, his new puppy sister, is expecting someone called Santadoodle to bring them all presents on Christmas morning. Hugo has never even heard of Santadoodle! Of course, Hugo doesn’t want Waffles to be disappointed, so there’s only one thing to do—rally his friends for their biggest mission yet! Luckily, these Good Dogs are always up for an adventure!
