Female Chihuahua Rat Terrier puppy

I have a female puppy that is 75 percent Chihuahua and 25 percent Rat Terrier. She has just recently received her first set of shots, as well as being wormed and examined by a veterinarian. When she's fully grown, she'll probably weigh around 10 pounds or less. The rehoming fee is $250 and all of her and her mother's photos are on the website. Only serious inquiries will be considered!!!!
