That's the way good dogs get ruined, I see the catahoula being ruined by bay pens and glass eye's and the BMC being ruined by the $. There will always be true dog men who keep, work and breed the better dogs but there harder to find than most people think. I think the really good line of dogs are rarely if not never for sale on the WWW or the free paper cause " Good " dogs sell there self to good dog men and good dogs are busy working, not producing 3 litters a year from the same gyp. It's just as tough to find really good BMC, hounds, heelers and Catahoulas around here for sale, the good one have homes before there ever born.
most true dog men don't care about the money...They care about identifying/selecting the top performers in the litter and then using this pup or pups in improving the bloodline and they try to place the other pups with someone who can breed back to their dogs if the dog meets his/her requirements/expectations.
I have seen the doberman , rottwieler, great dane, german shepard, red nosed pit, blue pit and a few other breeds get too popular and once this happens the breed goes south pretty quick.
