Dinosaurs. Cardio. Chaos.
When a time machine malfunctions during a routine dog walk, Pebbles the Pug finds herself face to face with a T-Rex who’s… jogging? Yep. This prehistoric powerhouse is determined to get in shape—and she’s not taking no for an answer.

But something’s not right. The treadmill’s possessed, the gym smells like hotdog-flavored sweat, and the T-Rex’s workout playlist might be controlling the entire facility. Pebbles has to dodge rogue dumbbells, navigate a jungle-themed gym, and help this giant dino find her groove before the machine takes over everything.

Perfect for ages 6–11, this chapter book is a high-energy ride packed with laughs, dinosaurs, and one brave little pug with a big heart.

• Full-color illustrations
