The show follows Bluey, an anthropomorphic six-year-old (later seven-year-old) Blue Heeler puppy who is characterised by her abundance of energy, imagination and curiosity about the world.
The young dog lives with her father, Bandit; mother, Chilli; and younger sister, Bingo, who regularly joins Bluey on adventures as the pair embark on imaginative play together.
A six-year-old girl (roughly the size of a Cozy Coupe) who would later on turn seven,[36] Bluey has a sprawling imagination and is curious, nice, and energetic.
[37] Her friends include Chloe, Indy, Coco, Rusty and Mackenzie, and she has a big buddy named Mia.
Muffin, who is three-years-old (later four[36]), is a very energetic and loud child who can sometimes be selfish and bratty, but has a good heart deep down.
[12] Radley looks out for his family and is laid-back, but has an occasional tendency to zone out; such an instance of this is him mistakenly calling Bluey a boy because of her blue colouring.
Frisky met Radley while babysitting Bluey and Bingo;[52] they eventually develop a relationship,[8] and get married in Bandit and Chilli's backyard soon after.
She is Bob's wife, Bandit, Stripe and Radley's mother, and Bluey, Bingo, Muffin and Socks' paternal grandmother.
He is Chris's husband, Bandit, Stripe and Radley's father, and Bluey, Bingo, Muffin and Socks' paternal grandfather.
She died at some point prior to the events of the series, but is depicted in Chilli's memory in the episode "Dragon" as a loving mother whose kind words of encouragement foster her daughter's drawing skills.
[36] He has close ties with the Heelers; he frequently involves himself with his neighbours' games, and has befriended Bandit's brother Stripe.
Janelle is a Labrador Retriever, one of the Heelers' next-door neighbours, the wife of Pat and the mother of Lucky and Chucky.
She has a good eye for planning birthday parties and keeps up with modern trends, preferring to stick with a modern version of pass the parcel while Pat suggested putting only one present in the middle (as was the case during his time), which would be met with a strong reaction at Chucky's birthday party before the kids and parents slowly began to accept it.
While not generally as sporty as his brother, Chucky likes watching football and is starting to show an interest in the sport.
However, during the third game of a State of Origin series, Chucky has to choose between supporting the Maroons and the Blues, the team his mum Janelle barracks for.
[17] Judo also tended to be bossy and domineering,[60] but in later episodes is receptive to cooperating when playing with Bluey and Bingo,[17] eventually becoming closer friends to the two.
[63] Bluey creator Joe Brumm cites Dog from New Zealand comic Footrot Flats, also a Border Collie, as an inspiration for Mackenzie's design.
Rusty is quite sporty, and he aspires to play for the Australian national test cricket team when he grows up, which he ends up doing as an adult.
He has two siblings, Digger, his kind and caring older brother, and Dusty, his energetic little sister,[66] and his father is in the army.
The minisode "Alongside" reveals that she maintains a neat and orderly lifestyle, is proficient at sports (playing football and netball), and is learning the piano and violin.
She has a regimented diet, leaving her unable to eat wheat, gluten, sugar, salt, dairy and food with any added ingredients.
He has a pet guinea pig that ran away, and is implied to have two mothers, making him and his family the first LGBTQ characters in the show.
[67] A young girl who is curious about the world around her, she also has a mischievous streak, being blunt and sassy towards certain people, like her older brother Jack.
He allows Rusty to play cricket with his older friends, warning him that despite his age, he would have to brave the faster bowls.
[66] Winnie is a Chocolate Labrador who befriends Bluey upon her entrance into the same playground, where they played a game of Café with their dads serving as the customers.
[40] Captain, an American Foxhound, and Mia, an English Setter, who are the preteen-aged big buddies of Mackenzie and Bluey respectively.
There is an implied attraction between the two of them, in spite of their buddies' friendly rivalry, which eventually leads them to have a conversation about starting high school.
[80] Dougie is a deaf Cavapoo (a mix of a Cavalier King Charles Spaniel and a Poodle) who plays with the same stuffed toy turtle Bingo finds at the park.
[84] Fido is a Chocolate Labrador who befriends Bandit on a playground; the two are drawn by their respective daughters, Winnie and Bluey, to serve as customers in their game of Café.
The Busker is an Irish Terrier who entertains others as a musician,[72] offers music lessons,[70] and has also officiated Radley and Frisky's wedding.
