The greatest friendship on earth is at risk when the constellation that powers Pup Academy fades out and humans no longer want dogs as best buds.
Spark explains her side of the story after leaving the Academy, but Corazon and Whiz soon find out it was all part of Professor Fitz's sinister plans.
Everyone thinks Spark is the Chosen One according to school prophecy. But since Spark spent her life as a stray, she's not used to special treatment.
Some uninvited guests look to stink up this year's Howlathon during the harvest moon. But Corazon has a smelly secret weapon to stop them.
The pups need all the extra paws they can get to help break King out of Animal Control when he's snatched up after his hideout is suddenly raided.
It's the Howlers vs. the Growlers on the fetchball field. Will Spark be the first stray to win the MVP trophy, or will Bite take the title once again?
The guard dogs haven't seen a sign of Wolf in weeks, but D.O.G. can't shake the feeling that something wicked will try to ruin the pups' Graduation Day.
