767.04 Dog owner’s liability for damages to persons bitten.—
The general rule is that any dog that bites someone in a public place or is lawfully in a private place is liable for damages caused by the dog. The dog doesnt have to be a vicious animal, and the owner doesnt even have to know it was vicious to be liable. In addition, if the dog owner is a tenant and the landlord had some control over the dog being there, the landlord may be liable too. Watch for “bad dog” warning signs though, that will be the dog owner’s defense.
