Hey, Macy! Our one-year-and-one-month-old female is a small mixed-breed. She came to us as a bottle baby last year and was later adopted, but was returned to us when her adopter became unable to keep her. Macy is pre-trained, potty trained, and knows her basic commands. While she appears to be part Chihuahua, she has the personality and intelligence of a Border Collie, and we suspect she may also have some Pomeranian mixed in. Macy loves people and does great with other dogs.
