Authorities say they're found three dog carcasses and more than 40 malnourished dogs and puppies at a kennel in western Iowa's Pottawattamie County.

The dogs were discovered Sunday at Young Gunz Kennel, which sits about 2 miles (3 kilometers) southeast of Hancock. The kennel website says it specializes in breeding and training Labrador retrievers.

Court records don't indicate that any charges have been filed against the owner.

The owner, 35-year-old Dustin Young, told The Daily Nonpareil that he's sorry about what happened. He says one of the dogs contracted distemper, which spread and also killed two others.

Matt Wyant with the county says the inside of the business building was covered in feces and had no food or water for the dogs, while another building was in a similar state.
