Chihuahuas can have all sorts of problems & have small litters. If the buyer wants a show dog this entails running the puppy on until teeth etc are come through so hence the higher cost. Breeders can charge what they like & more is not necessarily better
Why E mail breeders when you can call them & speak to them first hand. E mails are ok if you have already contacted the breeder & are seeking an update. or you already know the breeder.
Chihuahuas are rather flavour of the moment with buyers so some breeders take advantage of this
I know a Chihuahua breeder & Champ show who has has one litter in two years & kept the puppies(all two of them)to show & she alway has a waiting list., she used an outside stud & the bitch had to have a C section due to inertia & she was spayed at the same time. If she had decided to sell a puppy she would have had to charge in excess of £500 just to cover the stud fee & C section costs. She had to hand rear the pupiies too
