Monday afternoon, Butler’s pug Lolita was attacked in New York City by a greyhound named Mayfly. According to The Ugly Truth star's rep (who also reps Lolita), the greyhound pounced on Lolita and bit her "so [Gerard] separated them to protect both dogs."
Then Mayfly’s owners called the police, but by the time officers arrived on the scene, Gerry and Lolita had fled, so no citation was issued.
Detective Martin Speechley of the New York Police Department tells E! News a report for harassment was taken from the greyhound owners.
"One owner stated to the other owner that their dog should be on a leash," the detective explains, "and they were cussed out because of it."
According to TMZ, Butler would be the owner whose dog was not on the leash, although he put Lolita back on after the altercation.
Mayfly’s owners also told the New York Post that Gerard "smacked their dog in the head," but his rep denies this.
Lolita "is recovering" says Butler's rep; Mayfly could not be reached for comment.
