Three years ago, Shaggy Rogers is hired at the Complex for his remarkable abilities as a dog trainer, sharing an empathetic bond with them. He is told that his project involves working with canines that are part of a military "smart dog" project to use in combat. At this point, Dr. Dinkley brushes past Shaggy, without saying a word, as she's too engrossed in her work. Shaggy tells her off, but Mr. Blattsky warns him that she's someone important, being best to stay away from her, as he also considers her to be spooky.
Shaggy and Mr. Blattsky have now arrived at the kennel's observation deck. After being warned that some of the dogs are experiencing behavioral problems, Shaggy observes a pack about to attack the original smart dog prototype, Subject 24602, sensing that he is weak. As Mr. Blattsky prepares a sedative spray to calm the other dogs down, Shaggy enters the unit as he notes that the other dogs will tear 24602 apart before the sedative can take effect and orders the other subjects to retreat. Mr. Blattsky is impressed, but also observes it was foolhardy and suggests that it would be better if 24602 was simply destroyed. Shaggy objects, and offers to teach 24602 how to defend himself. Left to his own devices and regretting the contract he signed for the job, he finds that 24602 has already formed a bond with him, as well as displaying a rudimentary ability to talk.

The following credits try to match how they are displayed in the comic as much as possible:
- By: Giffen, DeMatteis & Porter
- Hi-Fi: color
- Travis Lanham: letters
- Brittany Holzherr: asst. editor
- Marie Javins: steering the mystery machine
- In order to work at the complex, Shaggy had to sign a 200-page contract and 72 non-disclosure agreements.
- Despite taking place three years prior to the present-day events, Velma is drawn with Fred and Daphne on one of the upper floors, wearing lab coats.
- The Smart Dog Program was intended to benefit the military by providing them cybernetically enhanced, extremely intelligent canines to assist in both domestic operations and overseas combat.
- Shaggy is shown to be physically attracted to Velma upon first meeting her. The two had failed romances in Scooby-Doo! Curse of the Lake Monster and Scooby-Doo! Mystery Incorporated.
- Although unnamed, one of the Smart Dogs bears a striking similarity to Scooby-Dum or Yabba-Doo, being a white dog of similar size to Scooby.
- Other than Scooby and Scrappy, there are four other Smart Dogs; the aforementioned white dog, two black dogs, and a brown dog with similar coloring to Scrappy.
- Other than Scrappy, all the Smart Dogs are adult dogs.
- Shaggy's previous work experience includes working at a fast food restaurant. His uniform contains references to both Burger King (his crown) and McDonald's (the red and yellow color scheme).
- The number 24602 is one higher than the prison number of Jean Valjean in Les Miserables.
- When Shaggy saves Scooby from the other Smart Dogs, it's very reminiscent of Owen Grady's training methods in Jurassic World.
- Scooby Apocalypse: Volume 1 (February 1, 2017).
- None known
Inconsistencies/continuity errors and/or goofs/oddities
- Scooby is not wearing his implants in this story.
Mr. Blattsky: Well, good luck, Rogers! And if you happen to get disemboweled before the next time I see you... ...It's been a pleasure making your acquaintance!
