Justin Hartleyprobably won’t be doing any dog-sitting any time soon.

OnThe Tonight Show Starring Jimmy Fallon, Wednesday, theThis Is Usactor, 41, recalled toFallonhow watching a friend’s pet in college led to a woman pulling a gun on him.

Unfortunately, during the pooch’s stay, the German Shepherd escaped through Hartley’s window — which was left open because his beagle could not jump through it.

“The dog takes off through the window. I spent two days tracking this dog down,” Hartley remembered. “I lost like 15 pounds. I was running all over the place. It was unbelievable.”

He had to be creative when the newlyweds phoned to check in. “They called me like three or four times a day to check on their dog, and I always had an excuse,” Hartley said. “I was pretending to be the dog. I was making noises. They were like, ‘He sounds weird.’ I was like, ‘Well he’s really tired. He went on a long walk. He’s exhausted.’ ”

Hartley eventually located the dog across town. “I found him all the way on the other side of Carbondale in this woman’s backyard. I went into her backyard, and I cornered the dog. The dog was kind of spooked,” Hartley explained. “She comes out with a cordless phone with an antenna and a gun. I was like, ‘Ma’am.’ … I was like, ‘That’s a dog’ and explained.”

“So you and the dog are both spooked,” Fallon said. “That should be a movie.”

That movie would end with a bit of irony: Hartley had locked himself out of the house, and when he returned with the dog, he had to “break in through the window that he had opened.”
