How durable is Fijian Mahogany deck for my family of 4 with 2 dogs?

Mahogany will withstand the wear and tear of patio furniture and pets well, because it is denser than softwood traditional decks. Mahogany will also hold up extremely well to the outside elements of mother nature. If left untreated, it will patina to a silvery-gray color as it oxidizes giving you a rich, natural look. On the other hand, a coat of oil based stain, like SuperDeck or Penofin, can help it maintain its dark, rich tones.
