I'm not necessarily running a puppy mill, but I do have a few Shih Tzus that are not neutered. Basically, making the household breeders of the beloved dog breed in a way. But the money earned for selling the pups is kept strictly for the dogs' expenses (food, haircut, etc.) because, well, they are kind of pricey to keep, all things considered. The parent dogs in question have been breeding for years now and, IIRC, are already at their third or fourth generation puppies. Throughout the time that my pets have been producing offsprings, we've gotten a usual buyer whom I believe buys them in order to be resold at a higher price. Now, the said buyer is haggling to buy six Shih Tzu puppies at a substantially lower price, with the argument that third or later generation puppies are of "less quality" than their older siblings. For any Shih Tzu breeders out here, what's your take in that notion?
