The average size of a Chihuahua is around 6 inches (15 cm) tall, but they can vary in size depending on genetics and environmental factors.

Chihuahuas should appear well-balanced with a slightly longer than tall body, according to the American Kennel Club’s Chihuahua Standard.

Small breeds, including Teacup Chihuahuas, typically reach their full size between 6 to 9 months old.

To get an accurate idea of your Teacup Chihuahua's final height, measure them at six months old and multiply the number by 100, then divide by 75.

Genetics play a big part in determining a Chihuahua's size, so look at the size of your puppy's parents to get an idea of what to expect.

Smaller dogs tend to breed smaller puppies and larger dogs breed larger puppies, but it's not a guarantee.

Puppy nutrition is also crucial, as a high-quality diet with the right nutrients will help your puppy grow at a healthy rate.

If your puppy is on a poor quality diet, their growth might be affected, and they could become stunted or overweight.

Over-exercising your Chihuahua can affect their growth plates and cause premature closure, leading to abnormal growth and potentially shorter legs.

A vet can help you determine the right exercise amount for your puppy to avoid this issue.
