Royal Oak is being ruff-ruff on owners who have menacing dogs.

WWJ reportes that the city has a new ordinance that would require owners of “dangerous dogs” to carry $1 million in liability insurance, post signs, complete an obedience class with the dog, and keep the dog in a locked, fenced-in area. The ordinance takes effect on Thursday.
