I am NOT a dog breeder but I do see several problems with that flowchart and some of the people who respond on this site...
I have been around a few breeders in my life and almost without fail (there is always exceptions to any rule) they all try to discourage anyone from getting into breeding, unless for some reason or another it benefits them or they don't feel threatened by that individual. Of course some of you will disagree, but the simple truth is, they do. Just take this flowchart for example, that is all it does is try to discourage someone new from venturing into this endeavor. Now I have to ask myself, why? The only logical reason I can come up with is fear of competition, not "what's best for the breed"... which leads to the second problem I see.
Person after person saying we want "what is best for the breed." I have to seriously laugh at this statement, dogs have been breeding long before we stepped in, nature will automatically do "what's best for the breed" whether any of you like it or not. Now I am not saying science can't improve upon nature at all, but having a little age to me, I have seen some very healthy, wonderful animals come out of a non controlled environment. you can take two average dogs and breed a grand champion, then take two grand champions and breed average dogs... there is no guarantee, and many make it sound like there is. Now I am not saying science can't improve the chances, personally I don't know. But, unless you're a Geneticist that specialized in dog genetics, neither can you, nor the people who told you this was a fact. But judging from what I have seen in my life, it doesn't.
The next problem and by far the biggest one: the second step states "reputable breeder (one who follows the guidelines in this flow chart).
anyone who has a litter and not only wants to unload them, but NEEDS too will say whatever they feel they have to in order to unload said litter upon whoever they can. There is no way unless you know the person very well, that you will know whether they do or don't... and anyone that takes someone else word as fact without knowing for sure, is a fool. So the majority of you might as well just go directly from "begin" to "do not breed" unless you got your entire breeding stock from a family member, friend or source you KNOW you can trust. But there is also a problem with that, where did they get their stock from? And so on and so forth.
Now for the worst case scenario; well know reputable breeder ends up with a dog with papers and a wonderful looking pedigree... said dog came from someone they know who got it from someone they know, whatever. Dog's origins are from a sire that was registered but didn't have breeding rights, dam was registered and had breeding rights. Another dogs credentials were used for the dog without breeding rights... all are registered AKC, let's say, but the pedigree is faked. don't tell me it can't happen, my guess is at least one of you have a dog your using for breeding that came from this or something similar.
In other words, this entire posting in my humble opinion is a JOKE. But hey, who am I? Just my two cents...
