There is no demand for any animal.  There is a surplus of unwanted ones, the products of abandonment and failure to alter.  Just go to a local animal shelter, and you will find an excellent selection from which to choose, for just a few bucks.  OH!  YOU need some fancy pure-bred stud!  I See.  Well, too bad for you.  I've rescued animals from shelters most of my life, and I can't recall a single one that didn't turn out to be a magnificent companion!  You should witness their appreciation!

THIS would put breeders out of business.  And most importantly, no one needs a dog from a puppy mill.
