many, many warning signs here. here are a few:
they think the AKC standard is 6-7 lbs! no, the standard is not over 6 lbs.
they charge based on the size of the puppy.
no pedigrees are listed.
not all dogs are even AKC.
the health guarantee is very vague and they don't even take back a sick dog. you keep it
and they help with a "fair" amount of the costs of genetic defects.
looks like a high volume breeder. the dogs are not that impressive and wow are they over priced!
here is a link to the Chihuahua Club of America and a list of reputable breeders:
