Chihuahua Growth Chart
tiny ChihuahuaHow big will my Chihuahua puppy be?  How much will my Chihuahua puppy grow?  These are the questions that just about every Chi owner wants to know!

There is a method to estimate the weight that a Chi puppy will be once fully grown. This is done with a Chihuahua weight chart.  These, are of course, estimates.  However, this reference chart is usually accurate within 1/2 pound.

The size of the full grown adult Chihuahua will depend on several factors, including:
  • The size of both the parents
  • The activity level of the dog
  • If the dog receives proper nutrition
  • If the dog has any inherited genes which have skipped a generation, in other words...size can be affected by the dog's grandparents
Using the Chihuahua Growth Chart is easy!   All numbers are in ounces.   The Final Adult Weight numbers are in pounds

Your veterinarian will be able to tell you how many ounces your pup weighs.  You may weight your Chi at home if you have a baby scale that shows weight in ounces. Or you may use an easy formula to convert pounds to ounces.

If you only know your Chi's weight in pounds, you can easily convert that number to ounces by the following formula.

The number of solid pounds x 16 + the number of percentage of pounds.

Example:  For a dog who weight 1.2 pounds, the formula would be :  1 x 16 + 2 = 18 ounces
In other words:  1 (the number of solid pounds of the puppy) x 16 (the number of ounces in a pound) + 2 (the number obtained from the .2 in the pup's weight)

Example: For a dog who weighs 2.1 pounds, the formula would be:  2 x 16 + 1 = 33 ounces
In other words:  2 (the number of solid pounds of the puppy) x 16 (the number of ounces in a pound)  + 1 (the number obtained from the .1 in the pup's weight)
Directions for using the Chihuahua Growth Chart

1.  Look at the column all the way to the far left, going down until you find the age of your puppy

2.  Stay on that row and follow along to the right, until you stop on the weight that your puppy currently is.

3.  Follow down that column, all the way to the bottom, until you stop at the Final Adult estimated weight.
