First off, a puppy should not leave it's mother until it is 2 months old. It is vital for the pup to remain with it'S family so it learns proper socialization skills. A good breeder knows this, so that is your first red flag.
Second, KCI registration should always be included with all their pups since the litter should be registered. As the litter is now, this is the second reg flag.
Third, a good breeder will either include a microchip in the price beforehand.
I would look elsewhere. Nothing about that breeder sounds right to me.
