Sweetie was initially shown to be antagonistic, sneaky, greedy, and spoiled rotten. She tends to fake being nice when around the princess and earl. She doesn't appear to be afraid of the PAW Patrol as she has invited and mockingly told them to catch her after stealing the Barkingburg royal crown. She also uses her cuteness to trick others into getting what she wants. When Sweetie laughs, it usually ends with a snort.
She owns a robotic toy frog named Busby and two kittens she considers her minions.
When her plans go wrong or she is punished, she tends to blame others for her mistakes, primarily directing her anger towards her toy frog Busby.
Despite her role as an antagonist, she is nowhere as sneaky and conniving as Mayor Humdinger.
Sweetie is a smaller puppy (around Skye's size). She has white fur, purple eyes, pink eye shadow on her eyelids, and a dark brown nose. She has pointy triangular ears with fluff on the inside and fluff on each of her cheeks.
Equipment and Gadgets
Her pup-tag consists of a magenta collar around her neck with a pink crown.
Sweetie's pup-pack contains a pincer claw similar to Rocky's, but in a different color and a long vacuum snatcher, with a selfie stick.
Sweetie's vehicle is a purple roadster that can transform into a flying helicopter / car. It has the ability to unbuckle Sweetie upon command.
