Nowadays, many people raise pets based on their appearance, and the vast majority prefer small-sized dog breeds. It is because of this preference that a special dog breed appeared in the market, namely the teacup dog. As the name suggests, teacup dogs are about the size of a teacup, making them highly ornamental. So, why are teacup dogs so small? Let's briefly discuss this question below.

Teacup dogs actually originated abroad. Their appearance can be considered accidental because at one time, someone discovered that among a litter of newborn puppies, one puppy grew very slowly and even stopped growing after a certain period. Later, experts found that these dogs stopped growing due to a genetic mutation.

However, it was precisely this accidental discovery that sparked a craze for raising such dogs at the time. Everyone loved these dogs not only because they were very cute but also because they were very convenient to carry. After that, many merchants saw a business opportunity and began to specifically breed teacup dogs.

But these dogs are the result of genetic mutation, so their birth rate is very low. Also, because of their small size, raising them is quite troublesome, and their physical resistance is much weaker compared to normal dogs, so their lifespan is relatively shorter.

Currently, there are many varieties of teacup dogs bred, across many dog breeds. Although the small size of teacup dogs affects their estrus cycle, they still do have one. Therefore, raising such dogs requires a lot of care. If raised properly, they can accompany their owners for a long time.

The size of a teacup dog is about the same as that of a normal dog’s puppy and typically stops growing after several months. Because teacup dogs are very expensive, many people might try to pass off a puppy as a teacup dog. So, when buying a teacup dog, it is essential to check its parents to verify if it is a purebred teacup dog.

The above is a brief introduction to why teacup dogs are so small. Hopefully, it will be helpful to everyone. The current price of teacup dogs in the market is relatively high, and there is a reason for this. Because they are hard to come by, owners should take good care of them.
