Florida law on liability for dog bites:

 

David St. John, of the West Palm Beach law firm St. John, Core and Lemme, which represents more than 600 associations, said state law protects property owners from being sued by a bite victim if the owner displays a sign warning people of a dog. Given that dogs are allowed in the Mackeys' community and state law specifically protects those who use signs, the homeowners have a strong argument they are entitled to the sign, he said.

A sign also would protect the association, he added.   [If] the association … allow[s] dog warnings... owners who want different signs cannot claim the association is unfairly enforcing the rule.
