The newest and most horrible form of animal cruelty is called "trunking."
Trunking is where two fighting dogs are simply locked in the trunk of car.
Then the dogs fight to death as the owner drives around, blasting music to cover up the sound.
After ten or fifteen minutes, the owner pulls over, dumps the body of the dead dog and continues on with the winner, waiting until he heals up enough to fight again.
It's absolutely terrible and it's so good that there are people out rescuing these dogs, like Miami-Dade County Animal Services, who rescued a group of dogs that were thought to have been used for trunking.
Five adult dogs and four puppies were rescued from a man's home in terrible condition.
Check out the video (above) to see some of the cute pups who were rescued and to learn more about this horrible crime.
