Teacup Chihuahuas: Firstly, it is important to point out that “teacup Chihuahua”, “toy Chihuahua” or any other such term is not an official variety of Chihuahua.

Considering that the expected weight range (according to the standard) is 3 to 6 pounds, “teacup” would imply that the dog is or will be much smaller than what is normally anticipated. In other words, smaller than 3 lbs.

This is not only very uncommon but also dangerous. Adult Chihuahuas weighing less than 3 lbs. are going to be much more susceptible to hypoglycemia, cold intolerance, neck injuries including a collapsed trachea condition, and a number of other injuries due to their small size, including broken bones and other trauma.

If you happen to already have a very small adult chi (less than 3 lbs), it will be more imperative to ensure the regularity of small meals to keep blood sugar levels even (perhaps going to “free feeding” rather than scheduled meals), work to keep the chi from becoming cold (clothing may be required, even indoors), and pay more attention to ensuring safety both indoors and outdoors.

That being said, AKC breeders have an absolute obligation to produce litters with breed improvement in mind, which means dogs that meet the standard. With hobby breeders (who may disregard bloodlines and pedigrees) and puppy mill breeders (who do not care about any of this), it is not uncommon to see larger than average Chihuahuas.

Another reason that could trigger this problem with your Chi is that you may be feeding your then an imbalanced or unhealthy diet, or you may be over-feeding your Chihuahua. Don’t be deceived by their small size and begging. Chihuahuas are notorious for their big appetite.

What to do about an overweight Chihuahua?

If you happen to have a larger than average Chihuahua, it will be important to establish whether this is due to body structure or excess weight.

Although looking at the rib cage (when wet, no outline of any ribs is visible) can be a general indication of excess fat, it is best to have your vet make this determination.

If it turns out that your Chi is simply more structurally large than expected, there is really nothing at all to worry about. In fact, your Chihuahua will be more well-built than his smaller counterparts and therefore less prone to certain health problems and injuries.

If your veterinarian indicates that it is time to help your Chi lose a little weight, this can be done with minimal effort by feeding lower-calorie options and increasing his activity levels.

It is not possible to have a guarantee by any means. However, if you obtain your Chi from a reputable breeder who has been breeding for quite some time, there is a better chance of knowing the final adult size in advance, at least within a pound or so.
