The concern here is the Continental KC. One of my boys is dual registered Canadian Kennel Club and AKC so I am as respectful of the Canadian KC as the AKC but this is the confusion that the Continental KC counts on to the unsuspecting public. If you give papers with the registered name on there and mark LIMITED it won't make any difference to those breeding Continental KC. Believe it or not all they require are pictures of the dog and one other persons written statement that the dog looks like the breed they are trying to register it to be. More than the hoax that I think they pull on the purchaser are the reasons selling limited are done. Puppy too small to breed, genetic history of producing something unacceptable, puppy is not a good example of the breed, and many more reasons. But who knows what kind of environment they are being kept in. If they'd lie about wanting a pet puppy they will lie about anything. I've gotten very cynical about peoples motives.
I really don't produce that many litters a year and the people that work with me are satisfied because I work very hard to have healthy, happy, well adjusted puppies. There are very few puppies that have ever left my home that were not fixed before hand and when they go to pet homes, the purchaser sends a small dep. that I use to get the spay/neuter done and they get a puppy that they don't have to worry about the surgery. If someone doesn't like me, my puppies, my getting the puppy fixed before leaving they probably won't buy from me. If I was selling a show puppy or a breeding puppy, those arrangement wouldn't be made on YT but I can guarantee that I'd tell them the name of the sire and dam so they could look into it before purchasing. I don't sell many open reg or show potential puppies so again I wouldn't put that info in a YT ad.
Hope that clarifies things for you.

Thank you for your suggestion. We periodically do review the For Sale forum rules and we will keep it in mind the next time we revise the rules. We do suggest members do their own research when it comes to finding a breeder and verifying any claims a breeder may make, especially if that is important to them.

Currently the rules do state:

If you list a Yorkie having a Champion dam or sire, you must list the dam and sire's name as well as the registration (AKC, UKC, etc) of the Champion.
