Janko is oversized (will weigh in at 100 lbs +), affectionate and has such a happy personality. He loves children and will quickly their's and everyone's best friend. In protection Janko has a very unique look to him. When "turned on" he goes from happy to "explosive" aggression. It is INTENSE, and very convincing. An added plus with Janko is he also very adaptable to living and interacting with dogs large and small.
