Dolly is voiced by E.G. Daily.
Dolly looks like a stereotypical poodle. She mainly has pink fur, but some of it is light baby powder pink. Her eyes are a darker grayish-pink with two black eyelashes on each eyelid and has a black nose. She has a perm that connects to her ears. On each ear she wears two bows, one purple, the other blue. She has the light baby powder pink fur around her neck, on her rear, tufts of it on her ankles, and on the tip of her tail, in a round-like shape. She also has a purple bow on her tail. She speaks with a heavy southern dialect. Unlike regular Pound Puppies, she has a pink hexagonal gem stone on her red collar.
When she first arrived at Shelter 17 (In "The General"), she acted very feminine and manipulative, using her looks to get the male dogs to do things for her. Cookie later confronted Dolly about this, but Dolly responded by saying it was how she motivated others. Dolly then offered to help make Cookie more feminine. The next day, Cookie, all dolled up and acting ladylike, ended up taking the act too far and disrupting their adoption scheme. Dismayed, Dolly admitted to Cookie that she was wrong to try and change the boxer, convincing her to return to her old attitude in time to save the adoption scheme. Before departing, Dolly gave Cookie a simple pink bow as a way of reminding the other dogs of her femininity.
In "The Really Weird Dog", Dolly was promoted to "top dog-in-chief", and contacted Shelter 17 to alert them of Rover's arrival. However, a malfunction in communications prevented her from telling them what kind of animal Rover was.
In "Hot Dawg!", she sent Pound Puppy agent Antonio to work at Shelter 17, in the hopes that Lucky and his team would be able to put an end to Antonino's "discipline problem" of getting romantically involved with female agents.
