What sort of health tests do the parents have? How about temperament of the parents, any titles or working certifications to give an idea of that?
I think if you are buying a pup from parents with no health testing at the minimum, you are really taking a gamble. You may be "saving money" on the purchase price but you are more likely to end up with health issues in the future and are more likely to spend a lot more at the vet in the long run. Of course there is no guarantee at any dog will be healthy but if they are not breeding with health in mind they are more likely to have issues. If they are not doing any health trsting or anything, IMO it's not worth it to buy a pup from someone like that because what exactly are you paying for, just lining the breeder's pockets? You may as well get a rescue, and save a dog rather than support someone who is breeding for money and not contributing anything to the breed.
