Sky Budin received a call early Tuesday morning from Kimberly Jackson. She said an alligator was hissing at her three dogs on her Loxahatchee, Fla., horse farm.
Budin came over with his 9mm handgun and put two bullets in the 5-foot alligator's head, the Palm Beach Post reported.
He said he doesn't like hurting animals but when he saw Jackson fending the gator off with a pitchfork he had to act.
"It was him or us," he said.
A trapper with the Florida Fish and Wildlife Conservation Commission retrieved the alligator but gave Budin a warning.
Commission spokeswoman Dani Moschella said if Budin hadn't killed the gator right away it would have gotten angry and attacked.
