Chihuahua Estimated Growth Chart

The chihuahua weight chart is great to use as a guide to estimate a mature weight of a puppy within a quarter of a pound or so. This table is only a guide, however, because many things can affect the mature weight of a puppy; weight may vary depending on bloodline, genetics, how well the animal is fed, etc. Weight estimates before the age of 8 weeks old are often inaccurate because the puppy is still nursing or being weaned.
