We have heard from so many people who got a pup from a breeder who told them it would be "no bigger than three pounds", only to have it end up 10 pounds! I advise people who care about the size to ask for weight records. Knowing the size of the parents cannot solely predict the adult weights. Two large parents can produce a small pup, two small parents can produce a large pup; any parent can produce any combination of sizes. Don't simply take a breeder's word for it. If they promise you the pup will be small, request some sort of records from their past to show you! On the other hand, some long time breeders know their bloodlines so well that they are comfortable estimating the adult size based on their history. If this is the case, they'll have records of this.
Many people ask: "Are your puppies 'teacups'?" The short answer is "no". There is no official definition of a "tiny," "teacup" or "micro" puppy. These are made-up terms for marketing purposes only. A "teacup" is something to drink out of. : ) Chihuahuas are part of the "toy" breed. We do not attempt to breed for puppies smaller than 3 pounds, as they tend to have more health problems. Our puppies are sturdy and healthy -- not fragile. Our average puppies weigh 4-1/2 to 5-1/2 pounds full grown.
If you are searching for a "teacup," we encourage you to search the terms "teacup myths" on the internet and educate yourself, to learn about the potential health problems these small pups tend to have. It's true they are cute, but we believe it is far better to have a sturdier, healthy puppy than a fragile extra small one.
