The ARPC is for the most part a pretty "closed" club. On occasion a member slips in that doesn't really fit the profile or subscribe to the same breeding practices, but current members do really try to screen prospective members and prospects usually get in after proving they involve themselves in showing/proving and then breeding to improve the color.
A more PC way to say that is ARPC advocates AKC as the only standard by which the poodle should be judged and you will find that the breeder members all (except for a very few) participate in AKC events- whether conformation or obedience, agility, working, etc, test and then selectively breed to the best/proven and tested studs.
That said, I'll address the too many litters theory. MOST ARPC members, myself included, are breeding a litter for their next show dog/rally champion/Working Achieve and do in fact (well not me - but I might have 2 litters this year) have several litters a year. To discount a known top producing kennel because of the number of litters would potentially be to discount a beautiful/quality bred pet. Think Dassin, Litlanns, Donnchada, Unique, Kaylens all top names producing some of the best known and top quality poodles alive.
When you are told to watch out for too many litters, it would be better said to evaluate what the breeders are giving back with their litters. Are they breeding brother to sister just to produce and sell? or are they breeding to improve their line - choosing the most select and investing, qualifying, testing and then breeding again?
You will see kennels producing lots of litters, not showing or participating in anyway in the qualifying of the breed, not testing and therefore not improving the breed (which should be our goal as breeders)!
Those are the ones to really evaluate.
Opinions always differ, but that is mine.
