On the eve of Best Medicine‘s series launch, Josh Segarra is tipping his hat to the four-legged scene-stealer, Wattson, who plays mischievous pup Copernicus in the Fox comedy.
A Furry MVP
Segarra, 39, tells News Of Los Angeles he ignores the old warning about avoiding kids and animals on set.
> “Best actor on our set right there, playing Copernicus,” he says of Wattson. “I love that pup.”
Between takes, the actor-dad to Gus, 9, Hank, 5, and Bo, 2-snaps photos of Copernicus and police-station pig Sprinkle to share with his sons.
- Copernicus sprints through high-intensity scenes, prompting Segarra to chase after.
- The surreal moment hits when directors yell “cut” and Segarra reflects on his dream job.
- Working with animals, he adds, is “always a fun day.”
Stacked Cast, Real-Life Fans
The Doc Martin remake pairs Josh Charles as traumatized Boston surgeon Dr. Martin Best with Annie Potts as his small-town aunt Sarah.
Segarra signed on as local Sheriff Mark Mylow after geeking out over Charles since Sports Night.
> “I’ve got so much respect for him. Now that’s my bud,” Segarra says. “This one has been honestly so easy… I’ll follow him into battle any day.“
He’s equally star-struck by Potts:
> “She’s a legend… so warm and would tell me funny stories… such a joy to be around on set.“

Both actors bond over raising three boys each-Segarra’s trio and Potts’ sons Clay, 44, James, 33, and Isaac, 30-and have “cried together” while filming nostalgic parent-child scenes.
