Chihuahua Weight Chart

Many readers look for a teacup Chihuahua weight chart so that they can estimate how big their teacup Chihuahua will be when it is full grown. Other Chihuahua owners may be looking for a size chart so that they can build a puppy wardrobe and outfit their little pooch with some designer duds.

Whatever the reason, please take a look at the generally accepted Chihuahua weight chart below. Please note that it is from a book authored by Hilary Harmar, called “The Complete Chihuahua Encyclopedia.” It was published in 1972 and found in the appendix and labeled as: “The Chihuahua Weight Chart”.

Remember that this is just a guide. And even though it is a solid guide, nobody can predict with absolute certainty how big your Chihuahua puppy we eventually become. Genetic influences from multiple generations may influence the future size of your teacup Chihuahua.

If a teacup Chihuahua breeder guarantees you that your dog will grow to a certain size, you should be extremely hesitant to deal with this person. Such a comment would be misleading and arguably fraudulent.

Moreover, beyond the obvious impact of genetic DNA, a myriad of other factors will influence the eventual size of your Chihuahua at maturity. This includes access to quality food and clean water, access to veterinary care, amount of exercise and owner lifestyle, and so forth.
