The man wanted on a bench warrant, after failing to show up to court on Tuesday morning, has turned himself into Thunder Bay Police.
Frank Vantroba, 57, was supposed to start his trial this week at Superior Court. He faces a charge of criminal negligence causing bodily harm. Three days were set aside for the trial.
One of Vantroba's dogs, a boxer, allegedly attacked a boy at Tarbutt Park in November 2012.
Thunder Bay's Licensing and Enforcement division also charged Vantroba under the Dog Owner's Liability Act with failing to have four dogs - two adults and two pups - licensed and leashed.
Vantroba's next court date is on March 24.
