NOx = male, eight mouths old, gray and white, but DNA is carrier of 4 colors. NOx is a head strong male, about 58 pounds. Will gain another 10-15 pounds when fully grown. Loves to play ball and go for walks. Adopted his sister, then got NOx a week later. Our family already had a rottwieiler and 3 dogs is just to much to handle. Forced to sale to great home.
