On average, Chihuahua litters range from 1 to 4 puppies, with 2-3 being most common. It's important to remember that:
* Litter size is not an indicator of a Chihuahua's future size. A "teacup" Chihuahua can be born in a large litter, and a standard-sized Chihuahua can be born in a small litter.
* It's unethical to intentionally breed for extremely small sizes. Teacup Chihuahuas are often more susceptible to health issues due to their size.
If you're considering getting a Chihuahua, it's best to find a responsible breeder who prioritizes the health and well-being of their dogs.
