People pay 250k for a horse if they race them, or breed more to race. It's a business ivestment.
What is the going rate on a normal Chihuahua? It's nowhere near 6G's, unless it's a show dog, or a show dog quality breeder. They pay that much for show dogs, because they're an investment. The guy from Coney Island was ready to put out 3G's and show it, too, because it was an investment.
Most freaky animals ARE put down, unless someone finds value in them. They also tend to have shorter lifespans than normal animals.
How do freak shows degrade animals more than dog shows? Most dogs I've seen like attention.
