This breeder seems very shady. I would never buy a Newfoundland from them. Both the mom and dad look like mixed breeds and have no paperwork or pedigree to back them up.
With Newfoundland breeders in particular, the reputable ones (and the ones that truly care about the breed) require meeting you first and sometimes even require applications be submitted so they can know more about you and the sort of family the puppy will be raised in. They also test and certify their dogs extensively to ensure their health (hips, elbows, heart), so that the unhealthy traits aren't carried into their breeding. You'll often have a contract written with the breeder as well that covers such things as if you're not able to care for the dog anymore the dog must be returned to the breeder (you can't just sell the dog off) and other conditions about raising the dog.
