IMO if a person is asking "Should I breed my dog" on internet, he/she is not ready for the responsibility.
Its like do I want to have a child?
It is something only the couple can and should decide after consulting experienced people.
In dog breeding the problem is a bit different, as one also has to find home for the pups.
If i ever have a really good female that I want to breed, I would go for partnership with an experienced breeder to arrange the stud and share the resonsibility of finding home for pups.
But even that is a lot of head ache. Why complicate my life? Better to enjoy the dog I have
Just because someone knows their dog is wonderful and breedworthy, and goes ahead and breeds without asking the question, doesn't make him any better than the fellow who does question it, or his dog any more worthy of breeding.
To the lurkers here, the message is quite clear, do not ask questions, because questions qualify you as unqualified. And that is really too bad.
We need people who have good dogs to breed them. Sorry, I know that isn't a popular stance, but breeders die every year. And the demand for pups is up, not down, like we tend to suggest all the time. We need breeders who are willing to go the extra mile for dogs, to buy dogs with good pedigrees, to train and try the dogs, to agonize over whether the dog is breedworthy, to do health checks on the dog, and then to go forward and breed the dogs. Because, the demand for puppies will be met, either by breeders who are new and trying to do the right thing, or by the puppy mills breeding another bitch and another bitch, and another. The only way to decrease the demand on puppy mills is to increase the supply from people like those on this forum who have decent dogs and want to try their hand at breeding.
These people will give the bitches a good life. They will try to use a good dog for their bitches. They will consult breeders they know. They will get help from experienced people for the whelping and raising of the puppies. They will try to find the best possible homes for the puppies.
What has changed in the past ten to twenty years, that our breed has taken such a dip both in temperament and health? One thing is that breeding should be left to professionals, and fewer people are breeding their dogs, and many, many more dogs are being mass produced, sold at pet stores, sold through the internet, dumped in shelters. And generally going to whoever can drop down enough cash on the right day with no questions asked.
So when someone asks, "should I breed my dog?" our response should not be, "well, if you are asking, no." Our response should be, "Lets see what your dog has, and what you should still accomplish before breeding him or her." I think we should take breeding back from the high volume breeders, and mentor some people who seem willing to learn what it takes.
