A new set of regulations meant to crack down on puppy mills in Ohio will take effect in the new year.
Dog breeders who produce at least nine litters and at least 60 dogs in a year will need to get a state license
Those who buy from breeders and sell to pet stores must also get a license.
The law also sets standards for housing and care of puppies and dogs that include making sure kennels are clean and properly ventilated.
The Columbus Dispatch reports that legislation regulating puppy mills has been seven years in the making.
The Ohio Department of Agriculture says 300 people have identified themselves as high-volume breeders. The department has about 100 license applications in progress.
