Chihuahua Weight

The American Kennel Club and countless other breeders agree that chihuahua weight should be between 2-6lbs. This is an ideal weight, a chihuahua's weight can vary depending on my factors, like bloodline, size, genetics, etc. But if a chihuahua is fed right, and gets a decent amount of exercise, he/she should fall within this range. Usually, chihuahuas weighing at or over 9lbs is considered obese.

A chihuahua that is smaller than normal (the dreaded teacup chihuahua term), will weigh closer to 2lbs. On the other side of that, a chihuahua that is larger than normal will weigh closer to 6lbs, or slightly over. These factors, mainly genetics and bloodline cannot be controlled.

Chihuahua weight can be controlled by watching what the dog eats, and making sure he/she gets enough exercise. Chihuahuas should only eat a reasonable portion of dog food. I always recommend Royal Mini Chihuahua 28 dog food. Sure a little taste of human food is fine every once in a while, but dogs should eat dog food.

Always consult your vet about you dog's ideal weight.

Chihuahua Weight Chart

The chihuahua weight chart should only be used as a guide and is intended only for purebred chihuahuas.

How to use the Chart:

The left-hand column of the table gives the age of the chihuahua puppy in weeks.

To determine the puppy's expected weight when fully grown, weigh the puppy in ounces and then compare the line of figures (ounces) against the number of weeks of age. Take the figure nearest to the present weight of the puppy.

The expected adult weight of the chihuahua will be given at the foot of the column in pounds.

NOTE: Weights before the age of eight weeks are liable to vary.
