What is the name of Bluey's border collie friend?

Bluey’s border collie friend is named Mackenzie.

Mackenzie is one of Bluey’s classmates and closest friends at Glasshouse Primary School. He and his family moved to Australia from New Zealand, giving the character a connection to both countries that appears in several stories. His breed is part of the show’s character design: Bluey’s friends are represented by different dog breeds, while Mackenzie is specifically a border collie.

Mackenzie first appears in “Fruitbat,” an episode from the first series. He is energetic, direct and naturally talented at herding and jumping, traits associated with the working history of border collies. His big buddy at school is Captain, an American Foxhound.

The other options are also Bluey characters, which makes this question easy to mix up: Snickers is a dachshund, Indy is an Afghan Hound, and Rusty is an Australian Kelpie. Series creator Joe Brumm has cited the border collie Dog from the New Zealand comic Footrot Flats as an inspiration for Mackenzie’s design.
