Whether your state holds dog owners strictly liable for bites or follows the one-bite rule.

How it worksStrict liability for serious injuries
LawC.R.S. 13-21-124

Under strict liability the owner usually pays even if the dog never bit before; under the one-bite rule you must show the owner knew the dog was dangerous or was careless. Provoking the dog or trespassing can bar or reduce recovery. Homeowners and renters insurance often pays dog-bite claims.
