Summary

Bay County does not ban or restrict any dog breed. The county repealed its rebuttable pit-bull presumption in 2011 and instead regulates any animal, of any breed, that is declared "vicious" based on documented behavior: a prior bite, attack, or a demonstrated propensity to injure people or other animals.

These county ordinances apply to unincorporated areas of Bay County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.
