However, it's important to note that:
* Litter sizes can vary: Some litters might have only one puppy, while others can have up to 6 or more.
* Size is influenced by factors: The size of the mother Chihuahua, her age, and overall health can influence the size of the litter.
* Veterinary care: It's crucial to consult with a veterinarian for proper care and monitoring during pregnancy and birth to ensure the health of the mother and puppies.
