There is not such thing as a “tea cup” anything..except what you drink from.

A Teacup is not a breed, but a size under 4 pounds. Most common breeds are Chihuahua, Pomeranian, and Yorkshire terrier.

The American Kennel Club (AKC) recognizes 21 canine Toy breeds, or breeds of diminutive stature. The term “teacup ” is not a breed, but slang for an undersized dog from one of these groups Teacup dogs are small enough to fit in a teacup, giving rise to the name. Often the term is used loosely to drive up the price of a puppy, as some people find the extremely small size desirable. In reality, “teacup dogs” often have special medical needs, health issues, and tend to have shorter lifespans than their normal-sized brothers and sisters.

One commonly found medical problem among teacup dogs is hydrocephalus, or “water on the brain.” Fluids build in the brain, causing pressure against the skull.

While any dog can be a victim of hydrocephalus, it is more common among teacup dogs. A teacup dog might also have thin, weak bones, blood sugar disorders and other medical problems arising from unfavorable genetic factors.

One reason for the problems associated with these tiny dogs is that many are the result of mating two runts to produce very small offspring. Runts, while deserving of a good life, often have medical issues that, when bred with another runt (or even a healthy dog), weaken the offspring and breed rather than strengthen it.

A “runt” of a litter is actually a premature puppy, one born to early. Given the fact that most breeders breed there dog on 2 or 3 different days there are puppies concieved on those day. But when labor starts all puppie are born no matter what day the are concieved on.

So breeding two very small dogs with eachother will produce smaller puppies and when the cycle is repeated enough..you get theses tiny dogs. I adopted a Chihuahua that was a rescue and considered a Tea Cup” she weighed 2 pounds full grown, 5 1/2 inches tall and about 8 inches long..she was 4 years old when she died from complications due to low blood sugar.

Hope my info helps you out..reconsider buying these tiny dogs..put breeders who care more about making a dollar off of them then they do their health, out of business…. anyone who tells you they are healthy..well I have a bridge I want to sell you.

There is no such thing as a “Tea Cup” chihuahua – Myth or otherwise. The term “tea cup” or “tea cup myth” is only a sales pitch term to ask more $ for the runt of a litter.

Chihuahuas are supposed to be 6 lbs and under, with the 4.5 lb range preferred.

Size depends on what their parents were built like. There are two body types of chihuahuas. One is slender with long legs and the other is short and square built.

A well bred chihuahua might be only 10″ high at the top of it’s head or up to 18″, but there are many back yard breeders who sell pups from the over sized dogs that should not have been bred at all. Ask to see the parents of your chihuahua and you’ll have a better idea of what it will be when older.

I heard a lady on the radio complaining about how difficult her 12 pound “teacup Chihuahua” was to train. Now purebred Chihuahuas generally range in size from 4 to 8 pounds. SO she paid more for her “teacup Chihuahua” and got a dog that was poorly bred and bigger than normal Chihuahuas in the process.

Get a puppy from a responsible breeder selling regular not “teacup Chihuahuas” and you will have a much better and healthier dog.

A Chihuahua of good breeding should weigh less than 6lbs full grown.

All dogs grow differently- when your dog is about a year old, you’ll know how big she’s going to be.

What? They don’t exist and they are generally unhealthy. There is no ’set’ weight for them to be when they are older. Badly bred chihuahuas can be as little as a pound and a half as an adult. I have a seven pound chihuahua who is so teeny, people ask me if he is a baby. They don’t have to weigh next to nothing to LOOK that tiny.

EDIT: They are just chihuahuas that are bred to be very small, usually resulting in health problems. They are not a seperate breed.

By ‘Myth’ you mean not real right? Because ‘tea cup’ Chihuahuas dnt exist, they are just poorly breed real chihuahuas. So their size just depends on how deformed they are.
