Sissy, she is about 6yo (we gave her a birthday of 11/4/2011) and she is about 9 pounds. Sissy is a good mom. She is a little protective of her babies since she arrived on the transport but she tolerates her foster mom carrying them and holding them. Her tail is always wagging! Sissy (we are told from the transferring shelter) is very sweet and gets along with other dogs, cats, and older children due to her size and current her shy temperament. We are sure once she settles we will see the same sweet loving little girl. Are you looking for a small dog to round out your family?
