Apparently many residents don`t know about a new ordinance that changes the way dogs can be chained to objects. The ordinance, which passed in November, makes it a crime to chain your dog to a stationary object. Instead dog owners must use a trolley. A trolley is a tether attached to a cable run. The cable run must be at least 10 feet long and mounted 4 to 7 feet off the ground. The dog must also be able to access water and shelter. Animal control officers continue to see dogs chained to stationary objects. Right now they are giving warnings. Citations could carry a $500 fine.
