A national report called " A Horrible Hundred: Problem Puppy Mills in the United States "from the Humane Society of the United States list problem puppy mills.
That list includes six Indiana breeders.
The report list operations with deficiencies and inadequate attention to animal welfare based on data from USDA inspection reports.
The report looks at widespread issues in the puppy mill industry which include mills where the dogs are kept solely for breeding purposes and are usually kept in cages 24 hours a day, seven days a week.
At some of the Indiana mills dogs were found in the freezing cold without protection from the weather and underweight dogs without adequate food.
Some of those mills were found to abuse and mutilate the animals.
The Indiana breeders listed in the report include Marlin Bontrager of Rome City, Elam Fisher/Morgan Creek Kennel of Williamsburg, Kathryn and Vernon Lambright/Clearspring Kennels in Wolcottville, Elmer Lapp/Pine Hill Kennel of Hagerstown, Steven Lapp of Modoc and Larry Miller/Railside Canine of Millersburg.
