Captain Stella makes her first big call by choosing a new tactical officer. But when the crew embarks on its next mission, there's a stowaway on board.

On the planet, Garbage and the crew try to save an angry, capable canine who's gone feral. But who will rescue the rescuers with the Pluto gone?

Taming the beast can be tough. Kira faces her great fear: brunch. Meanwhile, Garbage must jump through the hoops of Penelope's training scenarios.

Unleashed, the Pluto team explores a planet that might be perfect for humanity. But something - or someone - stinks. Also, Loaf must take the lead.

Awww-some and then some: The cute - and chaos - factor rockets out of control when Stella discovers that her crewmates have turned into puppies.

Which comes first: a seed or a world? Dogs or humans? After failing to talk an alien into handing over planet-saving seed, the crew attempts a heist.

Love hurts. Garbage and the team stumble on a world that seems to be populated by their beloved owners. But what are these odd shape-shifters hiding?

In it to win it. Eager to compete in a mech war, Chonies looks to Garbage for help. But he's been pulled into Kira's plan to change canine minds.

Opposites attract - or not. Garbage and Happy must work together if they want to avoid disaster on a magnetic planet. Elsewhere, Kira goes on the run.

Dogfight. When a pooch goes rogue, two rival crews battle as one. They must fight to get back to the base, save the mission - and more.
