How do I tell how big my Chihuahua will get? ›

Additionally, if you purchased your Chihuahua from a breeder, you can reach out to them about your pup's estimated adult size. Your breeder should be able to give you a precise figure based on previous litters of puppies and the size of your Chihuahua's parents.

Chihuahuas usually reach their adult weight between 9-12 months of age. The average weight of a Chihuahua is between 2.5-4.5 lbs and 5-8 inches tall but this can vary between dogs. In general, standard Chihuahuas shouldn't be over 6lbs in weight.

Over-sized Chihuahuas

If your Chihuahua is well over 6 pounds, the first thing to assess is if this is a matter of body structure or excess fat. If this is simply your dog's natural body structure, don't give this any more thought; the majority of Chihuahuas are larger than 6 pounds and are perfectly healthy.

Chihuahuas are known for their impressive longevity, with many living well into their teens. The average lifespan of a chihuahua is typically estimated between 14 and 16 years. Notably, the longest living chihuahua on record is Megabyte, who reached 20 years and 265 days.

For example, here's a formula that Wisdom Panel™ veterinarians recommend: Multiply your pup's weight at four months by two to get an estimate of their adult weight. So, if your dog weighs 15 lb. at four months, their adult weight may be around 30 lb. (give or take a few pounds).

You can estimate your puppy's full-grown weight by using our puppy weight calculator, which follows the simple formula: Adult weight = (Puppy weight / Puppy age in weeks) * 52.

Chihuahuas generally shouldn't be over 6 lbs in weight and they shouldn't have too much fat covering over their ribcage and waist.

For instance, a healthy Chihuahua might live to 15 or even 20 years old, while medium and large dogs tend to live between 10 and 13 years old. The Chihuahua is also a relatively healthy breed of dog, which can help extend their lifespan.

But the proper way to count puppies is to do an x-ray around the last week of her pregnancy when all the puppies' bones have formed so they'll show up on the x-ray. And that's the best way to count all the tiny skeletons and see how many puppies to expect.
