DES MOINES, Iowa (AP) – Nebraska and Iowa rank high on a list of states with what are described as some of the worst puppy mills. A report from the Humane Society of the United States says Nebraska ranks third on “The Horrible Hundred 2015” list, with 14 of the breeders. Iowa ranks fourth with 11 breeders on the list. The list was led by Missouri, with 23, and Kansas, with 16.

The society says its list doesn’t include all of the worst breeders. The Des Moines Register reports that a puppy mill is described by the Humane Society as “an inhumane, commercial dog-breeding facility in which the health of the dogs is disregarded in order to maintain a low overhead and maximize profits.”
