When Sweetie laughs, it usually ends with a snort.

However, she was replaced with Anya Cooke before the episode was released.

She was originally going to be voiced by Brianna Daguanno, who is also the voice of Luna Girl on Disney Junior's PJ Masks.

She is the second animal (seventh if one counts the Kitten Catastrophe Crew as separate antagonists) to be an antagonist in the series, the first being the Kitten Catastrophe Crew, and the first example of a pup antagonist.

Sweetie is considered to be a West Highland White Terrier.

She is given a different tiara, which appears golden with real jewels, in ' Jet to the Rescue'. Her Jet Rescue uniform is rose with black undertones and teal highlighting the helmet, visor, and her collar. Her pink vest is rose with lighter rose details like her Mission PAW uniform. Instead of a normal Mission PAW or PAW Patrol pup-tag, she wears a crown pup-tag. Her Mission PAW uniform is a black suit with pink and white trims. The 'crown' acts as a remote control to control Busby and it glows when activated. Her casual outfit is a magenta tiara and a magenta collar with a pink 'crown' attached to it. When in her Mission PAW uniform, her bangs are slicked back into a new hairstyle. She has pointy triangular ears with fluff on the inside and fluff on each of her cheeks. She has white fur, purple eyes, pink eye shadow on her eyelids, and a dark brown nose. Sweetie is a smaller puppy (around Skye's size). With her supporting the PAW Patrol alongside all their allies from the various sub-branches of the series, like Coral from the Aqua Pups, Tuck and Ella from the Mighty Pups, Al from the Big Rig Pups, and even Sid Swashbuckle's partner Arrby, whom she befriended, they manage to defeat Codi and stop her plan. As a result, she calls Ryder to tell him of what happened, and agrees to aid the PAW Patrol with stopping Codi with being brought to Adventure Bay with the Ferris Wheel when it is returned itself. In ' All Paws On Deck', she has her latest attempt to steal the Crown of Barkingburg interrupted by Codi Gizmody sending the Adventure Beach Ferris Wheel to Barkingburg, catching her by surprise as she takes evasive action to avoid it, causing the crown to fall of her head, much to her frustration. She did stop when she was given a new tiara, much to her delight and gratitude towards the Princess, as she participated in an airshow with the PAW Patrol as part of Skye's birthday present for the Princess.

At the end, though, she tried to nab the Princess's necklace, meaning that she hasn't gotten over her greed completely. However, in ' Jet to the Rescue', she revealed a more anti-heroic side and was not happy when she saw that the Princess was in danger, showing that she has standards and that she actually does care for her owner. She is rather indifferent to the Princess and has no qualms with backstabbing her and/or taking advantage of her naivety. When her plans go wrong or she is punished, she tends to blame others for her mistakes, primarily directing her anger towards Busby. She owns a robotic toy frog named Busby whom she considers her minion. Her overconfidence is often her own undoing because she sometimes fails to foresee how her plans could go wrong. She refuses to give up on her goal to become the queen of Barkingburg.

She is a picky eater and hates fish, bananas, and normal dog food. She also uses her cuteness to trick others into getting what she wants. She does not 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 has a British accent and often pretends to be nice when around the princess and Earl to manipulate them. Sweetie is shown to be antagonistic, sneaky, greedy, and spoiled rotten.
