Fredericks, a hotel owner, had a dog named Sport that he had trained as a watchdog. When Vincent Zarek, a guest at the hotel, leaned over to pet the dog, it bit him. Although Sport had never bitten anyone before, Fredericks was aware of the dog’s violent tendencies and, therefore, did not allow it to roam around the hotel alone. Vincent brought an action for injuries sustained when the dog bit him. Is Fredericks liable for the actions of his dog? Explain.
