Did NCIS: Origins Just Kill Off Fan-Favorite Gary Callahan the Dog After That Harrowing Stabbing?
NCIS: Origins delivered a gut punch as Franks’ canine partner Gary Callahan was stabbed in the line of duty — but did he make it? The Tuesday, April 7 episode pairs tender flashbacks of how Gary entered Franks’ (Kyle Schmid) life with a present-day suspect chase that ends in blood and a desperate race to save the team’s most loyal member.
Yes, they stabbed the dog. NCIS: Origins went for the jugular this week with an episode that put K-9 hero Gary Callahan in the worst kind of danger and then did something you probably did not see coming.
What happened to Gary
Tuesday, April 7's episode jumps between how Gary first ended up with Mike Franks (Kyle Schmid) and a present-day chase that turns brutal. During the takedown, Gary is stabbed. It is bad. The blade hits several nerves that control his back legs, and the vet says he will not walk again.
- Flashbacks show Gary entering Franks' life.
- In the present, Gary is gravely injured while chasing a suspect.
- The knife damages nerves tied to his hind-leg movement.
- The vet delivers the prognosis: no more walking.
- The episode closes by cross-cutting Gary's induction ceremony with his retirement ceremony.
- At retirement, Gary rises and takes steps to accept a medal for courage and valor.
- He is still on the job afterward, splitting time: weekends with Franks, workdays with Herm.
'Maybe it was just grit or hell, or maybe it was a miracle, but in that moment, Gary Callahan stood up and took his first steps - for the second time,' Mark Harmon as Gibbs says in voiceover.
The way the show edits between 'welcome aboard' and 'goodbye' while Gary stands back up is both a gut punch and a pretty effective bit of TV melodrama. And for anyone wondering: no, they are not writing him out. Gary stays an agent, with a shared custody-style setup between Franks on weekends and Herm during the workweek.
Where Origins sits in the NCIS timeline
Origins premiered in October 2024 and winds the clock back to a young Gibbs (the role Mark Harmon made famous) less than a year after his wife and daughter were murdered. Season 1 plants him at the NIS Camp Pendleton office, trying to do the job while carrying all of that grief. The series is fully pitched as a prequel but not a homework assignment.
What the creators are aiming for
Co-creator Gina Monreal told Us Weekly in April 2025 that the goal was twofold: give long-timers a show that feels right alongside NCIS, and make it easy for new folks to hop in from the pilot and get attached to these characters. She also stressed that they are strict about canon to honor the mothership (both she and fellow co-creator David J. North wrote on NCIS) while still digging into new faces and their emotional lives. In other words: the lore matters, but so do the people.
Monreal and North said they got to do pretty much everything they wanted in Season 1, with one caveat: they wished they had squeezed in more Gary. North even joked about a hypothetical spinoff called 'NCIS: Gary Callahan.' Not saying no one would watch that.
When to watch
