Chihuahua owners love these dogs due to their big personalities wrapped in tiny bodies. But did you know that even the tiny Chihuahuas vary in size? Smaller Breeds, such as regular pet Chihuahuas or teacup Chihuahuas, are great examples.

To make sure your tiny dog has the correct weight range appropriate to their respective size, we have put a comprehensive size and weight chart together for Chihuahua pet parents.

How Big Is a Chihuahua Dog?

Chihuahuas are small dogs. They are one of the smallest dog breeds around.

This toy breed can vary in size depending on the specific breed. There are Apple Head Chihuahuas and Deer Head Chihuahuas, with the deer heads being thought to be slightly bigger than the others.

Contrary to pup-ular belief, coat types do not influence the size of your Chihuahua puppy.
 

At What Age Does a Chihuahua Reach Its Full Size?

While they grow the most in the first few weeks, generally, Chihuahua’s growth should slow down at around six to nine months, but will likely gain weight until up to a year, which should not be too significant.
 

What Is the Ideal Weight For a Chihuahua?

A perfectly healthy Chihuahua can have an estimated weight between 1.5 to 3.5 kilos.

Female Chihuahuas tend to weigh a little less, with typically anything around 2.3 to 3.3 kg, while the male Chi can range from 2.8 to 3.7 kg, in general.

Below, you can find a weight chart that will give you a better overview of what weight your pup should have as an adult if this is its weight at eight weeks old:

  • 0.3 kg at eight weeks – 0.9 kg as an adult
  • 0.6 kg at eight weeks – 1.8 kg as an adult
  • 0.75 kg at eight weeks – 2.25 kg as an adult
  • 0.9 kg at eight weeks – 2.5 kg as an adult
  • 1.1 kg at eight weeks – 2.75 kg as an adult

Please note that these are pure estimates to give you a general idea of what to expect your Chi’s size to be when they are fully grown. These sizes vary within a litter but also depend on your dog’s gender.

How to Make Sure Your Chihuahua Isn’t Overweight

Chihuahuas are an active dog breed; therefore, you should not struggle too much with Chihuahua weight gain unless it is due to an underlying health condition. Dog nutrition and dog sports play a big role in keeping a healthy weight for your dog.

Feeding your Chi high-quality food and limiting treats is definitely one way to go. On top of that, these little dogs should get enough exercise to avoid any weight-related health problems such as low blood sugar.
 

Ensuring Your Chihuahua Grows Properly

To ensure healthy Chihuahua puppy growth, the American Kennel Club recommends frequent meals of high quality, suitable for small breeds.

Your dog food should consist of enough protein, carbs, fatty acids and fibre. Too little or non-nutritious food can cause your Chihuahua puppy to be stunted.
 

FAQs

Where are Chihuahuas from?

This small dog is thought to have been first bred in the 19th century in the Mexican state of Chihuahua, where it received its name from. The modern Chihuahua is likely to derive from a similarly tiny Mexican breed called Techichi.

How big is a full-grown Chihuahua?

The average size of a regular Chihuahua is about 15 cm, with the smallest breed being only about 10 cm tall. The smallest dog in the world was an adult Chihuahua that has only a size of 9.65 cm and was, therefore, in the Guinness World Record Book.

How do I know how big my Chihuahua will get?

According to popular sources, you can guess your pup’s estimated adult size at about six months old by measuring its size and then multiplying the number by 100 and dividing the result by 75.

The size of Chihuahua puppies from the same litter can differ as well. Therefore, speaking to your Chihuahua breeder and having a look at the parents for their size can also help you get an idea of how much your dog’s adult weight is.
 

Final Thoughts on Chihuahua Size & Weight

Tiny toy breeds are a fun, loving and low-maintenance breed for owners living in small apartments or not having much time to exercise their dogs.

The size of your dog and other Chihuahuas can vary significantly and will influence their weight. As with other breeds, it is recommended that you check in with your vet should you suspect your Chihuahua to have weight or growth-related issues.
