Although Florida does not have a state-mandated leash law, in Miami-Dade County, dog owners are prohibited from allowing their dogs to roam freely off private property. Dogs must be leashed at all times when on public property at the risk of a $50-$150 fine, depending on whether the dog is sterilized or not. 32 percent of dog bites reported in Florida involved dogs that were roaming freely without a leash off of the dog owner’s property, according to the Florida Department of Health.
