Explaining the unusual way the pooch came into his life, the star revealed it was an on-set romance.
“She was a stray while I was filming up a mountain in Bulgaria. Stole my heart,” Butler added.
In the photo, the actor can be seen smiling at his new friend in a black and white snapshot of them.
While the actor has a new pal in his life, he’s still recovering from a motorcycle accident that left him hospitalized. He revealed details about his ordeal while on The Talk in October saying “I’m lucky to be here.”
“I went 33 feet through the air,” he said. “I did a somersault.”
Butler said he remembers a bystander looking on at the scene and simply saying, “‘Wow, you really are an action movie star.’”
The actor suffered “five fractures in my right foot alone, because I landed right on my knees, so I’ve done my knees in and my left foot. And this had been the busiest period of my career.”
He continued, “I was in bed for four days. I couldn’t get out of bed.”
