I'm always amazed at the stupidity of people who think that dog breeding is easy :(
I know of one woman who calls herself a 'Professional Breeder', She hasn't a clue :( has been breeding for as long as I've been alive and claims she was taught all she knew about breeding by
MY Grandfather!

Which is interesting as what he knew about Dog Breeding would have fitted on a postage stamp with room to spare. What amazes me is that in all that time she has learned very little about breeding and caring for pups
It was my
Father who knew about breeding, he was the type of person who would read up on things, research and had a mentor (more than one) , the one I knew was a local breeder and CH Show Judge who ran the local dog clubs/shows, ringcraft etc. Dad would stand at the side of a show ring and tell me which dogs would be placed, and where (and most importantly why) and was rarely wrong. He wouldn't have given this woman the time of day and was dead against breeding for the sake of it.
I did try once to educate her (tactfully) and was mightily rebuffed, I prefer not to speak to her now, it saves me wanting to beat my own brains out with a large stick.
