Without seeing your Chihuahua in person, it is difficult to determine if it is a teacup Chihuahua. Teacup Chihuahuas are typically smaller than the standard size Chihuahua, weighing around 2-4 pounds.

However, it's important to remember that "teacup" is not an official breed or size category recognized by major kennel clubs, and breeding for extremely small size can lead to health issues. It's best to consult with a veterinarian or a reputable breeder to get a better understanding of your Chihuahua's size and health. **
