Charming stray puppies Luna, Otis, Champ and Haggis find homes with new kid companions — and help a special friend escape a shady research lab.

Champ leads the pack back to the observatory after sensing trouble for Zeta — but not before they test their skills while saving a pet store on fire.

The pups make the front page with their heroics during the anniversary of the town’s infamous UFO sighting. A mysterious dog keeps watch from afar.

The pack follows Shepherd to the farm, where new animal mentors help refine their special powers in a series of tricky training challenges.

Emma, JJ and Tori help Andre look through his grandpa’s notes to locate the pack. The pups evade scheming security chief Rocco and crew on the farm.

JJ and pals decode messages in the sound waves and learn about the observatory’s secrets. With Rocco on their tail, the pups suit up in slick outfits.

Rocco goes through a slimy transformation after getting too close to Zeta. The kids and pup squad devise a clever plan to sneak into the observatory.

Zeta’s falling ill, and time’s running out to get her home. JJ’s baby sister might be the key to help the kids and pups reunite Zeta with her family.
