I'm sorry but that argument is not valid. This way of thinking is backwards.
Hypothetically speaking, a Lamborghini and a Camry cost the same to manufacture. However, the Lamborghini's worth and overall value is rated much higher than the Camry. Why would anyone in the right mind, settle for the Camry when someone else is getting the Lamborghini for the same exact price? Just because someone else promises to show off the sellers car? When you make a purchase, it comes down to the overall value of the product, not your future plans.
The same general notion applies here. If a puppy is rated to have higher conformation than another, both should be priced accordingly. Why would anyone pay the same as someone else, for something deemed "lesser". This doesn't make any logical sense.
On another note, temperament and health issues are NOT 100% avoidable just because you purchase from a show breeder. I know the first 8 weeks of a puppy's life are crucial, but I can't help but think the dog's experiences and training throughout the rest of his life might have a larger impact on it's overall temperament. I have also worked with a lot of abused and neglected dogs, and I know that a dog's disposition can be recuperated.
Oversized/warlock/king IS a gimmick. At least we can agree on that.
Um, wow.... Okay, then.
First of all, if the breeder used an outside stud (which most do), they have to pay a stud fee. They pay that whether they get one puppy or a dozen.
They pay for vet bills for the bitch, which cost the same whether she's carrying one puppy or a dozen.
Once the puppies are whelped, they have to take care of the puppies. Every single pup in the litter gets the same care, whether it's a singleton litter or a dozen pups. They get checked on and handled daily. With a bigger litter, the breeder actually puts more
time into dealing with them.
When it comes time to crop the litter, the vet charges the same price for each puppy. Vaccinations cost the same for each puppy.
At around 8 to 10 weeks, the breeder makes the "final" show/working/pet determination in placing them. Every single puppy has had the same care, vetting, and early socialization, but you want them to charge less for the ones that are deemed pet quality? It's not
like they're making money hand over fist by producing this litter. If anything, the best they can hope for is to break even.
And you're right, no breeder and absolutely guarantee 100% that every single puppy they produce will live a long, healthy life with no temperament issues. But they can certainly stack the odds in favor of that by selecting breeding stock that are sound of mind, testing for as many health issues as they can, and socializing the heck out of their puppies.
