“ | I'm not a idiot! I'm a intelligent person! Don't be disrespecting me! | ” |
–Dippy defending herself from Petey. |

Dippy is a recurring character first appearing in the third chapter of Dog Man, Book 'Em, Dog Man! This person was brain-dead after Petey stole all the books in the world, and apparently never recovered after all books were restored. After Petey enters her donut store, Dippy's Donuts, she acts extremely dumb, mistaking "donuts" for "bagels" repeatedly, resulting in Petey's storming out of the donut shop in anger with a bag of bagels.
Appearances
Dog Man
Petey goes to her donut shop because he wants to get some donuts, but she keeps messing up his order. She keeps saying that they sell them by the dozen, even though Petey asked for twelve (which is exactly a dozen). Then she says that they only sell them by sixteen. She understands, but says to the baker to make "sixteen bagels". Petey tells her straight, but she just tells him to make up his mind, then asks him if he wants mustard for his bagels. This causes Petey to start raging about how he doesn't want bagels nor mustard, only donuts. But this time, she lectures him and tells him that she's not an idiot and he needs to show her some respect and then she gives him his bagels.
A Tale of Two Kitties
She tries to adopt Li'l Petey from Petey selling it for free. Despite reading the sign "Free Kitty", she asked how much it costs, then Petey replied "a dollar!". After realizing she only has $10, Petey takes the dollars anyway. After her naming Li'l Petey 'Snowball', Li'l Petey replies, "I think I'll call you Poo-Poo Head." In disgust, she hands Li'l Petey back to Petey, and leaves furiously.
Dog Man and Cat Kid
We see her working at a shop called Cannery Grow. She acts like she does back in Dog Man. She doesn't know how to sort the numbers from 1 to 10, driving Petey crazy for 22 whole minutes. Petey yells at her, causing her to cry. Petey feels sorry. However, after a few minutes, Petey is driven crazy again and yells at her, and steals one of her bottles of Cannery Grow anyway. She outrages at Petey for doing this, and she thinks about calling 911 but is too stupid to do so. She can't find 9, and after finding it, forgot the number after 9 and never called 911.
Brawl of the Wild
She slams a danger sign over a hole just as the judge and the guard were climbing out, knocking them back in the hole, exclaiming, "I helped!" She is later seen in the burning theater, thinking it was a 3-D movie. Dog Jail inmates later saved her.

Trivia
- Despite all the books being returned to all the people in the world at the end of George and Harold's "benefits of reading" book, she still seems to be idiotic, possibly because she never owned any books, was mentally scared from the lack of books, or was never very intelligent to begin with.
- She is the only minor character from Captain Underpants that reappeared in the Dog Man Series.
- Her name, Dippy means stupid, no-brainer, or foolish, which she is.
- In Dog Man and A Tale of Two Kitties, her dress is short-sleeved but in Dog Man and Cat Kid and Mothering Heights, the dress is long-sleeved.
