Hague's appointment as Froozer's top executive came a year after a Canadian judge fined him $5,000 and banned him from owning or controlling an animal for three years following his guilty plea to a single count of causing an animal to be in distress. The charge is the equivalent of a misdemeanor in the United States.
Hague had been charged by authorities after the emergence of an July 2014 surveillance video from a Vancouver hotel that showed him tormenting a 5-month-old Doberman pinscher named Sade in an elevator.
Hague is seen on the video repeatedly kicking the dog. He also pulled hard on her leash, to the extent that the pooch's paws left the floor of the elevator. Sade belonged to a friend of Hague's.
Disclosure of the video sparked a massive backlash against Hague and Stamford-based Centerplate, which provides food and beverage services to major sporting venues, arenas, convention centers and other locations across North America.
In addition to public outrage, Centerplate clients were concerned about the situation, including the San Francisco 49ers football team, which condemned Hague's conduct.
"I take full responsibility for my actions," Hague said in a statement at the time to the Canadian TV network Global News. "This incident is completely and utterly out of character and I am ashamed and deeply embarrassed."
On Friday, Hague told CNBC that before he got into the elevator with Sade, the dog had pulled on its leash so hard that it dislocated two of Hague's fingers."
"I wish I could have controlled the incident with the dog better," Hague said. "Jesus, I'm fallible. I'm human. I made a mistake. ... I lost my temper, and I regret that."
