Also when it comes to limited registration, most field golden breeders do not offer limited registration. Most only do full registration. The whole limited registration thing is all about the show ring. Same with show labs, you'll probably only get limited registration from show breeders of labs, field labs are mostly doing full registration.
I inquired about a show lab (years ago) and the pups ran the same prices as show golden pups (about $1000 back then), limited registration, and mandatory fencing. The breeder is somebody who has no problem placing puppies. Keep in mind she is only breeding once or twice every year and is "out there" with her dogs being shown. This is all the advertisement she needs for her dogs. <= I did not get a pup from her because we have no fence and are unwilling to put up fencing.
Even other breeds which are not as popular have no problems placing the puppies.
It is "supply and demand" but also they are very selective about what they breed, how often they breed, and they are very well known in their breeds with them always getting referrals without any advertisement and even when they don't have puppies on the ground yet.
One comment on the breed (in general) and limited registration or lack thereof (in general) is that when you have everyone and his brother and sister breeding everything they have... you are going to struggle convincing puppy buyers to pay more when/if the quality is there.
And quality isn't just titles on the dog. It's also appearance. If you are buying a dog vs adopting a $10 mutt from an animal shelter.. it better be a nice looking dog. And then it is also health and temperament.
Any "gee I wish we all could do full registration and ensure people will be producing puppies for less money" thoughts going through our heads better go away quick with the reminder that labs are a mixed bag. You're not just talking about "prozac puppies". You are talking about dogs as aggressive in tendency as pit bulls are. This is major dog aggression and even aggression towards people.
That is why there is so much protectionism in golden retrievers among breeders. It's not just
about keeping pups out of the hands of "dumpers" (ie people who buy on impulse and dump the pups at 6-8 months).
