Dog fighting is disgusting. It is done for money and power and in some cases involves drug rings as well. You go into a home that has housed dog fights and you'll see videos of dog fights, dogs in the backyard, the pens where the dogs fight etc. Not only does this effect dogs but also other animals when dogs are being trained. Cats, rabbits, other small dogs etc. are used to train the dogs to kill. When a fighting house is taken over police often go along due to drugs and weapons also being at the house due to the thousands of dollars that are usually bet on in fights. The surviving dogs are taken to a shelter where they are treated but nearly all of them are euthanized due to the way they were trained and how they can't be adopted out to homes without the safety of the new owners being at risk.
