Hague was pet sitting for a friend in Vancouver on July 27 when, according to court documents, he allegedly repeatedly kicked a 1-year-old Doberman pinscher named Sade and yanked her leash so hard she was "lifted into the air."
The video showed a cowering Sade in the corner of the elevator before Hague began his attack.
Centerplate, an arena concessions provider, has had a series of escalating statements over the last few weeks regarding the investigation into Hague's behavior. The last statement was released Thursday announcing Hague's resignation.
"We want to reiterate that we do not condone nor would we ever overlook the abuse of animals," Joe O'Donnell, chairman of the board of directors for Centerplate, said in statement to Fortune. "Following an extended review of the incident involving Mr. Hague, I'd like to apologize for the distress that this situation has caused to so many."
