The dog that bit an 11-year-old boy in a Thunder Bay's Tarbutt Park last month did not have rabies.

The Thunder Bay district health unit quarantined and tested the boxer after the attack.

The health unit has told CBC News the results were negative.

After the incident the child had been given rabies shots as a precaution.

According to Thunder Bay's licensing and enforcement division, the dog has been returned to its owner.

The 56-year-old man faces a charge of criminal negligence causing bodily harm, because he allegedly failed to remain at the scene and help after his dog attacked the boy.
