These adorable, loyal, loving, dogs might have a rough appearance when they are older. But don’t let that fool you, inside they are loving, caring, and would like you to be their owner. I know at times some can be mischievous. Bernese Mountain Dogs are known to be loyal to their owner, and they would cost their life for the sake of there owner. I know this because I have my own Bernese Mountain dog at my house. His name is Sebastian.
