Pepe is Alison DiLaurentis's Shetland Sheep Dog, commonly referred to as a "Sheltie"; who was taken in from the animal shelter by her mother, Jessica DiLaurentis before she died. Pepe arrived at the DiLaurentis House the day Alison returned to Rosewood. He may have been the puppy seen in Season 2 but he first officially appeared in "Whirly Girlie."
Pepe is introduced in this episode when he is unexpectantly dropped off at the DiLaurentis' house. He was meant to be taken in by Jessica, but since she was gone, Alison adopted him instead even though her brother Jason thinks it's a bad idea. Her father, Kenneth DiLaurentis, disapproves of the dog. Emily walks Pepe for Alison since she is unable to leave her house. Pepe eventually digs up Jessica's body in the Hasting's backyard.
- This is Alison's second pet to be shown on the show--the first was Tippi, an African Grey parrot that first introduced in Season 4's second episode, Turn of the Shoe.
- Like Tippi, Pepe was also introduced in the second episode of a season.
- Pepe was only really introduced for the sake of him finding Jessica DiLaurentis' body
