How durable is Fijian Mahogany deck for my family of four with two dogs?

Fijian Mahogany is more durable than traditional softwood species such as Cedar or Redwood. It will take the wear and tear of patio furniture and pets better than softwood because it is denser. Mahogany also holds up extremely well outside. If it is left untreated it will patina to a silvery-gray color as it oxidizes. On the other hand, a coat of oil-based stain like SuperDeck or Penofin can help maintain the natural beauty of the material.
