I am not a breeder, nor do I claim to have anywhere NEAR the knowledge that some of our dear members here have, but I noticed a few red flags on that website. One of her dams is 2.5 lbs, another was 9 years old and still having puppies
If I were going to spend that amount of hard-earned money on a puppy, it wouldn't be from this breeder. Just my humble opinion.
Good luck in your search
