Yes, unfortunately this is true. These dogs are bait dogs and can be stolen, picked up at free give aways or pit bulls that do not want to fight. They, if small are just thrown into a pack of pit bulls. If larger, they can have their muzzels taped shut or their teeth filed/broken off.
It is also fortunate that I do not rule the world as anyone convicted of this crime ( it is a crime ) would be put to death.
