The District of Columbia has two statutes that, read together, eliminate the requirement of scienter in one specific set of circumstances: where the dog that bit the victim was at large because of its owner's negligence. (dogbitelaw.com)
The state of Florida, in particular, allows for scienter as a grounds for liability even on persons who are not the actual owner of the animal. (personalinjuryattorneysmiamifl.com)
These statutes therefore create a single exception to the one bite rule: the victim is not required to prove scienter if a dog bites him while the dog is at large and if the dog is at large because of its owner's negligence. (dogbitelaw.com)
