Chihuahua Growth Reference Chart

This chart has been around for ages. While it’s not exact, it can give you a general estimate of your puppy’s adult size. Simply check your puppy’s current weight vs. age and scroll down to get an approximate adult weight.

Example:
At 8 weeks old, a puppy weighing 13 oz is estimated to mature around 2 ½ lbs as an adult.

*** This chart is used only as an estimate. It has been inaccurate more times than we can count! But so many of our clients like to use it, so we have it here for you to see. ***
