This is another breed that lives a long life which is anywhere from 10-18 years on average. They come in many colors and with both long and short hair. They make good guard dogs as they are alert and will tell you if someone so much as opens a door. They only weigh about 8-10 pounds on average but they are hearty and as long as you train them, they are easy to maintain and housebreak. They usually like to cuddle up on laps of their family members and strangers.
