Teacup Chihuahua – The World’s Tiniest Dog


Teacup Chihuahua,Teacup Chihuahua pics,Teacup Chihuahua complete info,Teacup Chihuahua videos

The tiny teacup Chihuahua is a truly small dog. As an adult, could weigh around 5lbs, or even less.

Unfortunately, this miniature size causes some serious health issues. These include hydrocephalus, heart disease, and bone fractures, among others.

Standard sized Chihuahuas usually have long lifespans, but the health issues in teacup Chihuahuas can mean they live much shorter lives.

It’s really important to weigh up the pros and cons of a very small dog if you’re considering one. But this is what we will help you do.

We’ll find out what the term teacup Chihuahua means, and how being tiny affects the health of these scaled-down pups.

What is a Teacup Chihuahua?

Chihuahuas have been popular companion dogs for millennia.You might also enjoy our complete guide to the Chihuahua dog breed

The tiny teacup Chihuahua is a much more recent arrival on the pet scene, but the teacup Chihuahua is not a new breed of dog.

In fact, teacup is just a cute and catchy word that breeders and owners have coined to describe a Chihuahua who is smaller than the average.

How big is a full-grown teacup Chihuahua

So just how much smaller than a regular Chihuahua is a teacup variety?

The AKC places an upper weight limit on show Chihuahuas of 6 lbs, although many pet Chihuahuas are bigger than this in reality.

But the breed standard doesn’t stipulate a minimum weight. So without one, who decides when a Chihuahua becomes a teacup Chihuahua?

And what are the thresholds for mini teacup Chihuahuas and micro pocket teacup Chihuahuas?

Teacup Chihuahua Size

The answer is nobody. Teacup essentially means nothing but “small.”

Of course in any animal there is natural variation, and some are smaller than others.

Someone who breeds standard-sized Chihuahuas might one day find a smaller than average pup in their litter, and prefer to refer to it affectionately as a teacup pup rather than the runt.

Other breeders specifically pursue smaller Chihuahuas by breeding these small individuals together.

They might also decide their own weight bands and system of categorizing puppies, such as “teacup,” “mini” and “micro” Chihuahuas.

One of these breeders might decide that teacup means smaller than 5lbs.

Another might decide it means smaller than 4lbs. However, there’s no universally recognized consensus.

And many people consider these terms a business-savvy way of making undersized pups appear special and desirable

The Chihuahua Club of America has been robust in rejecting the idea that teacup Chihuahua has any formal, standardized definition.

Are Teacup Chihuahuas Good Pets?

Tiny dogs which don’t take up much space and look like puppies their whole lives are very appealing.

The puppy stage of dog ownership is an adorable period, made all the more bittersweet because we know it has to end.

Could a miniature teacup Chihuahua be the way to hold onto it forever?

Unfortunately it isn’t all good news. There are some important facts that you need to know before you take the plunge and purchase a miniature Chihuahua. And much of it is about health

Teacup Chihuahua health

The standard size Chihuahua has a number of health problems that are a direct result of being such a small dog

Several tiny breeds share these problems and they are strongly linked with being tiny.Even standard sized chihuahas have health problems caused by being small.

When we make tiny dogs even tinier, as you can imagine these health problems can become much worse.

For teacup Chihuahua puppies, the odds are stacked against them as they embark on life in miniature.

These are some of the conditions they’re at risk of:

Heart Disease

All teacup dogs show increased rates of heart disease.

Put simply, their hearts and bodies were never designed to be so small.

Instead of evolving and adapting gradually over thousands of generations, their organs have been dramatically scaled down very rapidly.

In this rush, their hearts have become unsuitable for the job they need to do, and breakdown or fail.


Teacup Chihuahuas come with teaspoon-sized tummies.

These small bellies can only hold very small amounts of food at a time, so teacup Chihuahua dogs need to eat regularly to stop their blood sugar from falling dangerously low.

As teacup dog owner, this means an inflexible commitment to feeding them every hour or two, and even through the night.

It’s a bit like having a forever baby, with sleep deprivation that could last for years


Another common problem for tiny dogs is difficulty toilet training.

Tiny bladders hold very little before they need to be emptied, and this means even an adult teacup Chihuahua will need to answer the call of nature many times a day.

Some teacup dogs may never master holding it in until their next walk, and need indoor solutions such as doggy diapers or a litter box.

Toilet training problems put dogs at a high risk of being relinquished to animal shelters or euthanased as many people find it hard to live with inevitable accidents

Bone Fractures

Part of the appeal of teacup dogs is that they look so dainty and delicate (try finding a breeder who doesn’t photograph them snuggled in a baby blanket, perched in fine porcelain, or even balanced on a stiletto shoe).

But of course, like that fine porcelain, teacup Chihuahuas’ bones are easily broken.

You’ll need to protect a teacup Chihuahua from collisions with clumsy feet, small children and other pets.

teacup chihuahua puppies are fragile

Even jumping down from the sofa can be too much for their fragile bones and cause fractures.


Hydrocephalus—or fluid on the brain—occurs when the flow of cerebrospinal fluid around your dog’s brain gets blocked, producing swelling.

The swelling causes pain and nausea, and sadly for many dogs the condition is ultimately fatal.

Hydrocephalus is a particular problem among Chihuahuas.

This could be entirely due to their size, or it could have a genetic component. (At the time of publication, the potential genetic connection has not been investigated, according to the Universities Federation for Animal Welfare.)

What we do know is that becoming teacup-sized only makes matters worse.

Other Conditions Affecting Teacup Chihuahuas

Of course, besides the hazards of being small, teacup Chihuahuas are still prone to all the other health problems dogs can inherit or acquire, and the conditions particularly associated with being a Chihuahua.

The health problems most commonly associated with the Chihuahua breed are:

  • luxating patellas (slipping kneecaps)
  • tracheal collapse (loss of rigidity in the windpipe)
  • atopy (predisposition to allergic reactions)
  • Legg Perthes disease (deterioration of the top of the thigh bone)
  • urolithiasis
  • eye diseases
  • periodontal disease (disorders of the teeth, gums and jaw)
  • and idiopathic epilepsy.

You can find out more about all of these conditions in our Chihuahua breed review and the reading section at the end of this article.

How Long Do Teacup Chihuahuas Live

As a general rule small dogs live longer than giant ones. And standard sized Chihuahuas do have a reputation for longevity.

You’ll hear stories about Chihuahuas that lived to twenty years or more.

But these are the exception and the evidence from studies carried out in 2004 and in 2013 suggests a much shorter lifespan of between 7 and 12 years.

That is for standard sized Chihuahuas.Does the dog in your life have a cat in theirs? Don’t miss out on the perfect companion to life with a purrfect friend.

We don’t have any data to confirm the longevity of teacup Chihuahuas.But all the evidence points to excessively miniaturized dogs having worse health than their standard sized cousins.It’s fair to assume that most teacup Chihuahuas will live to a maximum of twelve years and possibly have much shorter lives.

I hope you’re still with me after that onslaught of medical information.

It’s a lot to get your head around and a lot to think of a tiny 4lb dog dealing with.

Without a doubt, all life exists on a spectrum, and some smaller Chihuahuas will be blessed with good fortune and good health.

These are the teacup dogs breeders are likely to want to tell you about, but sadly it’s not representative of the experience of most miniature pups.

We’ll find out more about approaching teacup Chihuahua breeders soon, but first, let’s look at what owning a teacup Chihuahua entails.

Life With a Teacup Chihuahua Dog

Besides the constant carousel of meals and toilet breaks, teacup Chihuahuas are high-maintenance dogs in other ways too.

Even though they’re small and unsuited to long walks, they’re still dogs and need appropriate exercise and stimulation through games and interaction with you.

Small dogs are also more likely to be badly behaved, according to a survey of over 8,000 dog owners.

These survey results found that the smaller the dog, the more likely they are to have attachment problems, be afraid of or aggressive toward other dogs, and be more excitable and harder to train.

Another study found that Chihuahuas, alongside with Daschunds, are the breed most likely to attack people.

It’s not clear though if these problems are genetic, or if we’re just inclined to let small dogs get away with more.

Teacup Chihuahua Price

How much does a teacup Chihuahua cost?

One thing about teacup Chihuahuas is indisputable: These tiny dogs are big business.

Even though you’re taking home less dog, you can expect to pay far more for a teacup Chihuahua than you would for a normally reared Chihuahua.

Prices open at around the $1,200 mark, and some breeders command (and apparently receive) in excess of $11,300 for their teacup Chihuahua puppies.

And that’s just the tip of the iceberg. Because when you bring home your teacup Chihuahua, the purchase price is just the beginning.

How Much Does a Teacup Chihuahua Cost Over its Entire Lifetime?

Like all dogs, teacup Chihuahuas need somewhere safe to sleep (such as a crate where they can’t accidentally be sat or stood on)

They also need annual vet checks, flea and worming treatments, vaccinations, toys, and food.

These pups are likely to need a specialized diet for their whole life, and remember they’ll need feeding and a chance to empty their bladder every hour or two.

If you won’t be at home to provide this, you need to factor in the cost of doggy daycare to make sure your dog’s needs will be met.

And finally, it’s likely that these ultra-reduced dogs will be no stranger to the vet. As they grow up, the health costs rapidly spiral upward.

Because of the risks to health of miniaturising dogs it’s important that you factor pet health insurance into your budget,

Teacup Chihuahua Breeders

Since teacup Chihuahuas are a relatively recent development, it’s no surprise to discover their breeders are often tech-smart, with sophisticated websites and a smooth sales pitch.

Since we now know that deliberately breeding dogs to fall way outside their usual weight range puts them in danger of a lot of health problems, here are some things to consider when approaching a breeder.

The Chihuahua Club of America—the American Kennel Club’s official breed club partner—does not endorse or condone using the terms “teacup,” “micro,” “pocket size,” “tiny toy” or “miniature” to describe Chihuahuas.

Therefore “teacup Chihuahua” is a completely unofficial non-standardized term to describe very small Chihuahuas.

This means that a teacup Chihuahua might very occasionally be a small individual on the edge of the healthy weight range, bred by a responsible breeder committed to the welfare of future Chihuahua generations.

But more often than not, the term teacup is used by commercial puppy farms to market badly reared pups and sickly runts at the expense of their health and well being.

How to Avoid Puppy Farms and Unscrupulous Breeders

It’s hard to get around the fact that any breeder advertising teacup Chihuahua puppies for sale should be avoided simply for using the term “teacup”

So if you see a breeder advertising their Chihuahuas as teacup dogs, then our advice is to avoid them.

If you are looking for general Chihuahua breeders and hoping to purchase their smallest puppy, our article on “11 Questions to Ask When You Phone a Breeder” will also help you identify poor quality breeders.

Bear in mind that the Chihuahua Club of America recommends all Chihuahuas be registered with the Canine Health Information Center, and tested for cardiac disease, eye diseases and patella luxation.

Your breeder should have records of this for all their breeding stock and be happy to talk candidly about the other health problems facing very small Chihuahuas.
