Criminals involved in dog fighting operations use these dogs to “train” dogs intended for dog fighting. Sandy Dog Rescue, a non-profit animal rescue, recently came upon a heartbreaking case involving a lactating dog that was dropped off at a high-kill animal shelter, minus her litter of puppies. More disturbing still, she checked off the boxes of a bait dog: an animal basically “fed” by dog fighting rings to dogs weaponized as aggressive fighters.
