An Iowa man who ran multiple puppy mills across the state has been banned from selling, breeding, or brokering dogs and has agreed to give up more than 500 of them, which he kept in five properties across the state. 

U.S. Judge Stephanie M. Rose approved an agreement against Daniel Gingerich, whose main site was in rural Seymour.

The agreement settles a September 27 lawsuit the U.S. Department of Justice filed against Gingerich. The DOJ sued him on behalf of the U.S. Department of Agriculture, whose investigators visited his facilities 18 times in six months. 

The USDA said Gingerich violated the Animal Welfare Act at least 100 times since March.

Investigators said Gingerich failed to provide adequate nutrition, potable water, and veterinary care for his dogs, which caused "unnecessary suffering and death."

In a court indictment, prosecutors said Gingerich placed the health of the his dogs in "‘serious danger’ by exposing them to unsanitary and unsafe conditions." 

"(Gingerich) has placed the health of his animals in ‘serious danger’ by maintaining his dogs in facilities containing excessive amounts of trash, feces, and debris," prosecutors said. 

The Animal Rescue League of Iowa (ARL) and the American Society for the Prevention of Cruelty to Animals (ASPCA) are gathering the dogs, which will be sent to other shelters.
