Gandalf would be a good name for a Pyr. Mine is named Roxanne, Roxie for short. She was a gift from my daughter, who does lots better picking dog personalities than I do. Roxie is the biggest sweetheart and my landlord/best friend, a diehard dog person, would like most to bring Roxie up to his house. But she's almost never been indoors and frankly, doesn't like being confined. It's a hoot to watch a huge, hairy dog laying there with half a dozen kids using her for a playground.
