When we vacationed in Michigan, we met Otto, a 10-month-old Great Pyrenees.
According to PedMd, the breed "shows extreme devotion to its family and is mistrustful of strangers, whether canine or human. It remains well-mannered, somber, and placid, when not incited in any way. The Great Pyrenees is also very gentle towards children and its family."
When a neighbor stopped by, Otto introduced himself in typical puppy fashion. The neighbor engaged him in a little roughhousing, and Otto couldn't get enough of it!
Obviously, the neighbor had not read the PetMd article and had no idea what he had gotten himself into...
And to think he's still a puppy!
