First off, lets not compare working dog prices with pedigree or quasi pedigree dogs. Two different worlds and may they always be so....!
Secondly, if you are charging any more than £200 for a pup you are simply after a profit, no more no less!
In working dogs we should have the greater good always in mind, money shouldn't be part of it....
It don't matter what breeding is behind 'em, no matter what type or cross, if you breed for yourself, which should always be so, any spare puppies put on the open market should be at a price to make them accessible to all BUT the seller should do
