Allie is under a Chihuahua but she is bigger than the normal size Chihuahua. She weighs about 30 pounds. We also have her as not good with kids that is because we have not had her around kids and we are not sure how she reacts. She does react a little nervous sometimes when she meets new people but she is definitely sweet and loving when she knows you. She's got medium length hair and is petite. She would need some training and some potty training.
