Denver (AP) State lawmakers have killed a bill cracking down on puppy mills.
The House Agriculture Committee said Wednesday that the bill would have been tough to enforce and could hurt legitimate breeding facilities.
Rep. Beth McCann, a Denver democrat, says animals are being abused in some large breeding facilities. She says animals have been crippled in cages, injured and killed by people who raise them for mass marketing.
Her bill would have prevented dog breeders from keeping more than 50 adult breeding dogs.
