I understand the frustration and I am not even searching for a puppy to purchase.
Here on YT there is a correct procedure for posting puppies that "breeders" have for sale. Posting remarks comparing the small size of your puppies on others' threads is not a considerate thing to do.
Anyone that has puppies for sale should go to "puppies for sale" area and post a legitimate thread.
