Over the past few years it seems that teacup chihuahuas are growing in popularity. Why is it that so many people prefer them over any other dog? Well, chihuahuas are already the smallest dog breed in the world and having one means that it will be the smallest of the smallest and they many people think they are the cutest.

What most people don't know is that common terms like "teacup", "toy", "deerhead", or "applehead" are not defined as a chihuahua breed by any of the major canine organizations such as the AKC, CKC, or the UKC. In fact the only different official chihuahua breeds are long-haired and short-haired. The term is usually used to define a chihuahua which weighs less than the standard. It seems to be a popular term that most people and chihuahua breeders use and will probably be here to stay even if it isn't recognized as a chihuahua breed.

If you are looking for a teacup chihuahua don't always listen the breeder or the seller. Many times chihuahua sellers will claim to have puppies for sale. The fact is, no one can tell whether a puppy less than 10 weeks old will be a teacup size or not. Checking to see if the puppies parents are teacup wont work either. It is nearly impossible to determine if a chihuahua is going to be a teacup based on the size of their parents.

If you do decide to get a teacup chihuahua, be prepared to expect more health problems. Being the smallest dog in the world comes with its fair share of health problems including regulating their blood sugar (hypoglycemia), dehydration, and respiratory problems. They will need extra care and special attention especially as puppies and should always be checked out by a licensed veterinarian for thyroid and liver problems.

Being so small makes them much more likely to get seriously injured. Kids often like to play rough with them or can even step on them. If you have kids, please don't get a teacup chihuahua.

Dogs often lick the ground, sometimes ingesting fertilizers, cleaning agents, and other harmful chemicals in their system. This can be especially dangerous for teacup chihuahuas. Being so small makes their body much more vulnerable to low doses of toxins.

The weather will also affect teacup chihuahuas more than others. Consider getting your chihuahua a sweater for the winter time to give some extra warmth and protection.

Teacup chihuahuas can make wonderful pets. Just remember that smaller isn't always better. Make sure you have a healthy chihuahua over the smallest.
