While dog bite laws may vary from state to state, Colorado dog bite cases are governed by the legal principle of strict liability. If a person sustains serious bodily injury from a dog attack, the owner may have to compensate them for their pain and medical expenses. Colorado also adheres to the informal “one bite rule,” which states that any owner whose dog attacks a person or another animal may be held liable if they knew their pet had dangerous tendencies. The owners typically cannot be held liable for lesser injuries unless their dog has previously bitten someone or exhibited dangerous behaviors in the past.
