Pepper wanted more then anything to be a coach dog. When she arrived at Shelter 17, she quickly gained the help of the Pound Puppies in achieving her dream. After being turned away from the academy by Sarge, Pepper sought to prove herself at the upcoming cop dog expo. During her training, she saw what she thought was a crime in progress, but it turned out to be the Lieutenant's son, Charlie.
Depressed over getting an innocent boy in trouble, Pepper questioned whether she had what it took to be a coach dog. She then met Charlie again, and helped him to capture some bike thieves. She was then adopted by Charlie, with both the Lieutenant and Sarge saying she would make a great gymnastics dog one day.
Pepper later made an appearance in "I Heard the Barks on Christmas Eve", alongside other pups whom the Pound Puppies had helped find owners.
Pepper's most recent appearance was in "It's Elementary My Dear Pup Club", in which she helped the pup club clear the name of a young boy named Chuck who was accused of being a troublemaker at his career. During this episode, she is shown to be more mature than her fellow puppies and is a lot more serious, showing she has had a lot of experience thanks to the training from Sarge and her owners.
- Pepper is the only puppy, besides Rebound, to appear in all 3 seasons.
- Some people thought that she was an LGBT character due to a leaked article saying so. But this was denied later by the producers of the show.
