Beyond the title character,
Doug features a large
ensemble cast of characters. Many of the series' ancillary characters, among them Ms. Wingo and Mr. Spitz, are based on authority figures from Jinkins' childhood. • Porkchop (voiced by
Fred Newman): Doug's
anthropomorphic pet
Bull Terrier who is one of Doug's sidekicks and accompanies him nearly everywhere he goes. He sometimes assists Doug in making decisions and acts as his conscience. Porkchop is very talented in many things such as acting. He lives in an
igloo-shaped
doghouse in the Nickelodeon series, and a
tipi in the Disney series. During a Christmas special, it is shown that Doug got Porkchop as a Christmas gift and that Porkchop once saved Beebe Bluff's life when she was about to fall through some thin ice. Porkchop, along with Doug, originally first appeared in ID spots for the
USA Network children's block,
USA Cartoon Express. • Mosquito "Skeeter" Valentine (voiced by Fred Newman): Skeeter is Doug's blue-skinned best friend. He is a normal boy who is more sociable than Doug, though he occasionally makes honking noises. Skeeter and his family have lived in Bluffington for some time, so he helps Doug acclimate to Bluffington. For example, Skeeter helps Doug order food at the popular Bluffington restaurant Honker Burger in the series premiere (resulting in their friendship). The character was based on Jinkins' high school best friend, Tommy Roberts. • Roger M. Klotz (voiced by Billy West in the Nickelodeon seasons,
Chris Phillips in the Disney seasons): Roger is Doug's green-skinned nemesis, and a
school bully. However, he is not prominently shown as an actual bully, instead having
mischievous tendencies, playing
practical jokes on characters. He is older than others in his class, as it took him
three years to graduate from sixth grade. Roger has a crush on Doug's sister Judy and in certain episodes tries to woo her. Roger and his divorced mother lived in a
trailer park in the Nickelodeon series; in the Disney series, Roger's family becomes wealthy from a real-estate deal struck between the owner of the trailer park and the Bluff family. Roger was inspired from a bully who lived in the same neighborhood as Jinkins. He adopted the bully's neighbors' last name, Klotz, for the character. • Beebe Bluff (voiced by
Alice Playten): The heiress to the Bluff family fortune. Beebe is the daughter of Bill Bluff, the richest man in the town and a friend of Mayor White. The Bluff family is the namesake of the town of Bluffington, and in the second series, the school is even named after Beebe. Despite a certain air of superiority over her peers, Beebe maintains friendships with Patti Mayonnaise and most of her other contemporaries. Doug had his first kiss with her in the episode "Doug's Secret Admirer", although it was out of gratitude rather than love, since she already has a crush on Skeeter. Beebe was Alice Playten's final animated role before her death in 2011. • Judith "Judy" Anastasia Funnie (voiced by Becca Lish): Judy Funnie is Doug's older sister. Judy is very intelligent and especially dramatic. Unsurprisingly, she attends the Moody School, a school for artistically talented teenagers. Judy often gives or directs performances at Bluffington Elementary, which Doug initially dreads out of fear that Judy will embarrass him (as she has done in the past). Judy is usually seen wearing only purple and black, and rarely takes off her
beret or her sunglasses. She has a very strong
beatnik personality. Her actress, Becca Lish, also voices Doug's mother, Theda Funnie, his friend Connie Benge, bass player Wendy Nespah of Doug's favorite band The Beets, the hairdresser Fluke and many other characters. • Chalky Studebaker (voiced by
Doug Preis): Chalky is considerably the most athletic of Doug's main circle of friends, and he is an excellent student. He wants to follow the footsteps of his older brother, Cliff. • Connie Benge (voiced by Becca Lish): A naive schoolgirl who is best friends with Patti and Beebe, and also one of Doug's friends. She had a small crush on Doug in the Nickelodeon series. Although she was rather heavy-set in the first series, she lost weight between the two series and received a new wardrobe and hairstyle after going to a beauty camp for the summer, making her look quite different in either show. In certain episodes of the first series, the color schemes for Connie's hair and skin are switched, giving her lime green hair and violet skin instead of indigo hair and pale green skin. • Al and Moo Sleech (voiced by
Eddie Korbich): Nerdy twin brothers and two of Doug's best friends. Doug looks to them for technical help whenever he needs it. They tend to speak to each other using their own "twin language" using numbers for various words and phrases. In the Disney series, they skip all of the middle school grades and enter high school, but they maintain their relationships with Doug and others. They are each shown to have a crush on Judy. The two try to hide the fact that their father is not as intelligent as they are and is a hardworking doughnut baker. • Mr. Bud Dink (voiced by Fred Newman): A slightly odd, purple-skinned, dimwitted, retiree who lives next door to the Funnies with his wife and foil, Tippy (voiced by
Doris Belack). Doug frequently approaches Mr. Dink for advice, but sometimes it is useless. He and his wife's last name comes from an acronym:
Dual Income, No Kids, which supports Mr. Dink's spending on various things he claims as "very expensive". In later Nickelodeon episodes, Mrs. Dink becomes mayor of Bluffington, a role she continues in the Disney version. ==Production==
