Chihuahua weight chart

The chihuahua weight chart is great to use as a guide to estimate a mature weight within a quarter of a pound or so. This table is used only as a guide but many things can affect the mature weight of a puppy. Weight may vary depending on it's bloodline, genetics, how well the animal is fed, etc. It may weigh more or less then it's ideal weight depending on it's diet and if it becomes obese or not. Weight estimates before the age of 8 weeks old are usually inaccurate because the puppy is still nursing or being weaned and may be heavier due to fat from the mother's rich milk. This weight chart only works with purebred chihuahuas and a breeder that is knowledgeable about their bloodline (not just recognizing a bloodline's name, but recognizing the actual dogs as well).
