Diesel is a 2 year old, male Bernese Mountain dog mix. Diesel is a super guy! Great with other dogs and people. He is very loyal and enjoys being part of the family. We don't know how he is with cats yet. Diesel is perfect in the house, we don't crate him because he has wonderful manners. His favorite thing is to have a belly rub and if you can give him a good rub, he will be your best friend. Diesel would be best in a home that is quiet and calm. Although he is fine with children, we would recommend an older family who is looking for a loyal companion.
