This is one of those cases where I'd be happy to hear the breeder's side of things, or understand why somebody would breed a young dog vs waiting a few months. Why would you be in a rush to breed a young male golden? When he was apparently only a year old?!
You can probably make the argument that these people have known GOOD stock that they are breeding from and breedings may be lower risk than like say those cases where you have those other breeders who are breeding dogs they purchased for breeding
, who have a spotty clearance history if any at all, as soon as it is reasonably possible to breed them.
A good example would be Jacks' mom who I believe was a few months shy of 24 months when she was bred. They chose to breed her on prelims vs wait for her to come in heat again. This breeder is very experienced and knows the breeding stock of their dogs.... and there was no harm done since she got all the official clearances when she was old enough.
^ I didn't KNOW the clearances were prelims when I purchased Jacks. I probably would have backed away from the breeder had I known. And that would have been tragic since I adore Jacks.
My feeling is that when you have people breeding a young male - there better be a darn good reason for doing so - specifically since you do not have the "don't want to wait for next heat" excuse.
If a breeder makes a standard practice of breeding underage dogs, I would stay away from them.
*** On the subject - I know of more than a few breeders who cut corners and breed dogs who did not pass their clearances. Because a dog was "too good to throw away". I posted about one litter here in MI where I was initially head over heels in excitement about buying a puppy from a litter... the male was a point or two away from getting his GCH. The original breeder/owner gave up the dog when they found out his elbows did not pass. The breeder here in MI had a lot of people look at the elbows and decided to breed the dog anyway.
And there are a LOT of breeders out there who would NEVER breed a golden with a gay tail or a zipper nose... but they would breed a dog with a failed elbow clearance.
The above is why if you are a puppy buyer, you just have to be very careful while interviewing breeders.
Another breeder here in MI - she bred her golden who failed her elbow clearances to a couple boys who had excellent and proven structure. That may be fine or an easy gamble for some people, but not one I'd take. <- And I know this breeder and think she is otherwise an awesome breeder who is over the top concerned with the breed and very involved with the local clubs.
