It kind of just depends on what you're looking for in a breeder. A good breeder breeds only registered, to standard dogs. The most reputable (and in my eyes, the only important one) registry is AKC. Also, any breeder worth buying from would offer a health guarantee. 3 weeks after I got Franklin (from a bad breeder), he get sick with parvo and had to spend a week in the hospital. We didn't have a health guarantee and so we were stuck with the $1600 bill.
The breeder warning you about hypoglycemia is completely normal and lowering the price is also not necessarily a bad sign.
Do some research on breeders here at YT.. read the stickies at the top of every forum and they should point you in the right direction. I must warn you though, most reputable breeders do extensive testing on the parents to ensure a healthy pup. They also put lots of money into the care of the mother/puppies. This means that the puppies you find may cost a little more than $600. The average, I would say, is around $1000. Just because a breeder charges a lot, however, does not mean they are a good breeder. It's tough! Just ask us any questions you have and we will help you out as best we can. Good luck!
