Haas Chihuahuas do not sell Teacup Chihuahuas, there is no such thing as a teacup. A Chihuahua is a Chihuahua.

The official A.K.C standard describes the Chihuahua as a small dog that comes in two varieties or coat types. The difference in coat type (the Long Coat or the Smooth Coat) is the only official description used to identifiy a difference within this breed. Our standard does not categorize the Chihuahua by size.
For the purpose of showing and record keeping, the American Kennel Club includes the Chihuahua (along with 16 other breeds) in the toy group. Therefore, irrespective of their weight or physical stature, ALL Chihuahuas registered with the A.K.C. are considered to be a toy breed of dog.
As with all living things, there will be a size variance between individual dogs within the breed. Look within the human family-brothers and sisters will differ in height and in weight, as well as other physical attributes. They are described as humans, male or female and there is seldom if ever an need to break the description down further. The same hold true in regard to the Chihuahua; they are Chihuahuas-Long Coat/Smooth Coat, Male/Female.
Unfortunately, the additional adjectives used to describe the size difference and physical appearances are many; and have been misused for so long now they seem legitimate. Teacup, Pocket size, Tiny Toy, miniature or standard-are just a few of the many tags and labels that have been attached to this breed over the years. The Chihuahuas Club Of America is concerned that these
terms may be used to entice prospective buyers into thinking that
puppies described in this way are of greater monetary value.
They are not and the use of these terms is incorrect and
Occasionally, within a litter, there may be a puppy that is usually
small. That puppy is a small Chihuahua and any other breakdown
in description is not correct. To attach any of these additional
labels to a particular pup is to misrepresent that animal as
something that is rare or exceptional and causes a great deal of
confusion among those fanciers who are looking for a Chihuahua.
The Chihuahua Club of America does not endorse or condone the
use of any of these terms and would caution the prospective
puppy buyer not to be misled by them.
We recognize that many Chihuahua fanciers do want the very
small puppy. While they are adorable and can be perfectly
healthy, the buyer should be cautioned as to the extra care that
may be required with regard to their general health and well being.
