Good Boy

Owen, a 12-year-old neighborhood dog-walker, has saved up to prove he's ready for his own dog. His perseverance pays off when his parents finally let him adopt a scruffy Border Terrier, which he names Hubble. The moment marks the start of his plan to turn Hubble into his best friend.

Shortly after bringing Hubble home, Owen discovers he can understand every word the dog says. Hubble even utters a cryptic line: Take me to your leaders. The revelation hints at Hubble being more than an ordinary pet.

Owen learns Hubble is from outer space and part of a mission from the Dog Star Sirius 7. The dog is described as abnormally intelligent and sent to Earth to observe. Owen contemplates what this could mean for their relationship.

Hubble explains that dogs arrived on Earth thousands of years ago to colonize and dominate. The news unsettles Owen and the neighborhood dogs as they realize their destiny may differ from human bonds. The idea of dogs taking control conflicts with the love they share with their humans.

Owen, Hubble, and a rag-tag group of neighborhood dogs begin drills to pass muster for the Greater Dane. They organize routines, corrections, and teamwork to project confidence. The effort tests loyalty and friendship across the group.

The Greater Dane travels to Earth to assess the dogs and determine if humanity has kept its end of the bargain. She is accompanied by a Chinese Crested henchman and holds the power to recall all dogs if Earth dogs fail. The stakes are high for both dogs and humans.

Owen's efforts to guide the dogs do not convince the Greater Dane. She issues a recall order, threatening to pull all dogs back to Sirius if they do not meet expectations. The neighborhood is left anxious as the mass recall looms on the horizon.

In the wake of the setback, Owen repairs Hubble's communicator and manages to send a heartfelt message. He declares his love for Hubble, hoping to resonate with the Greater Dane on a bond beyond obedience. The emotional plea gives Hubble a renewed sense of purpose.

The Greater Dane asks Hubble where his loyalty lies, seeking a clear answer. Hubble requests to be called by his own name, Hubble, signaling his bond with Owen. The moment challenges the Greater Dane's assumptions about dogs and humanity.

The Greater Dane decides to return Earth dogs but imposes a major change: dogs are no longer a single breed, and Hubble must be separated from Owen by removing his ability to communicate with dogs. Owen's parents decide to stay in town for the first time, creating a more settled life. The plan reshapes human-dog relationships in the neighborhood.

Hubble is allowed to return to Earth but with the constraint that he cannot communicate with Owen as before. Owen, his parents, and the neighborhood begin adapting to this new dynamic. Hubble earns a place among Earth dogs, forming bonds through actions rather than spoken words.

With the new rules in place, Hubble returns to Earth and the family remains in town. The bond between Owen and Hubble endures in a revised form, and the neighborhood begins to accept a changed dog culture that values loyalty and love. Hubble fits in as a regular Earth dog while Owen continues to grow with his best friend.
