There is a method to estimate the weight that a Chihuahua puppy will be once fully grown. This is done with a weight chart. These, are of course, only 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 and up to 5 generations back
Preliminary Instructions Using the Chihuahua Growth Chart is easy: All numbers are in ounces. The Final Adult Weight numbers are in pounds. You may weigh your Chi at home if you have a baby scale that shows weight in ounces or the veterinarian will be able to tell you how many ounces your pup weighs.
