I have two miniature schnauzers and two mixed breeds. I have a white schnauzer and a salt and pepper. One is three years old and the other is nine months. They do like to be heard. They are very protective of home and family. My two mixed breeds are layed back and very loyal. They are easy going and I think just glad to have a home since I picked them up along the road nearly starved to death. They complete my home.
