I would like to thank Marcus Curtis and Old World Mastinos for the beautiful Neapolitan Mastiff puppy we received, THANKS MARCUS, for calling and for taking the time to answer our many e-mail questions, not only do we have Cassiopeia but I feel I've gained a friend, Cheers pal. S. Robertson, Toronto, Ontario, Canada.

Since day one, Marcus has been nothing but honest, kind, knowledgeable, and very respectful. Not only does he breed world champion Neos but his customer service and willingness to take the time and help guide you through the journey of owning one of these dogs sets him apart from all other breeders. If your in the market for a puppy I would give Marcus and the Old World Mastinos a rating of 11 out of 10 stars!

Old World Mastinos, was the perfect choice in selecting a Neopolitan Mastiff breeder. Marcus is incredibly knowledgable, very helpful and truly cares about the quality and authenticity of his dogs. Marcus continues to follow up with us and is always available for any questions we may have. We absolutely love our puppy. She is beautiful, healthy and strong. We could not be happier.
