Bio: Jazz is the daughter of Dodger and Angel. She's an only child, but doesn't mind not having any siblings. Jazz got her name due to her parents' love for music. She is shown to have Dodger's personality, but also has most of Angel's looks.
Besides her parents, Jazz also has the other dogs in the gang to look up to. Einstein, Tito, and Francis are her uncles and Rita is her aunt.
Jazz looks up to Dodger the most out of all the other dogs she knows. She enjoys walking around the city with him and helping him bring food home for everyone. Dodger also enjoys having his daughter with him. He loves her adventurous personality and her curiousity. Jazz is shown to be closer to her father, but also loves her mother. She enjoys talking to her mother and walking with her in Central Park.
I wrote an article about when Jazz was born. It also tells a little bit about what she does when she gets a little older, still in her puppy stage.
