COLORADO SPRINGS, Colo. (KOAA) — A Colorado Springs woman is continuing her fight to change state law after her dog was killed while in the care of an unlicensed pet sitter, arguing that dogs should be considered more than just property under the law. The pet sitter watching Julie Hsieh's dog Lumi, when Lumi died, was charged and convicted of a crime for running an unlicensed pet facility this month. According to the documents, Ratajczyk admitted to having five dogs in his care the day Lumi was mauled to death.
