My story

Here's what the humans have to say about me:

You can fill out an adoption application online on our official website.

UPDATE:  Rinaldo's fur and weight is looking amazing thanks to the TLC he has received from his foster Mom.  He is sweet and sassy, housebroken, has learned how to delicately take treats, manners when it comes to eating, and learning how to trust people.  He loves his Vet but protective of his home, just like any good Neo should be.  His only downfall is he does not do well with other dogs.  So there will be no exceptions, RINALDO WILL BE THE ONLY PET IN THE HOME.  A quiet home in the country is the perfect forever for our handsome boy.  

Please meet Rinaldo.  An approximately 2 year old blue Neapolitan Mastiff.  He found himself in a Houston Texas high kill shelter being brought in as a stray.  A caring person in Arkansas saw his post which reminded her of a dog she owned and passed away.  Having no idea he was a Neapolitan Mastiff had him shipped to her.  When he arrived she realized she was not equipped to care for him.  On June 29th, 2025, Rinaldo arrived at his foster home in Virginia.  He is heart worm positive and his slow kill treatment has already started.  His rear end is being treated for the flea infestation he suffered from.  Underweight at just 118 pounds his foster will definitely be putting groceries on that solid Mastino frame.  He knows sit and down but his leash manners surely need to be worked on which our foster is more than experienced to handle.  We know he rides well in a vehicle and seems to be a happy boy.  We will do updates on our Facebook page as they come in from his foster home.   If you are interested in Rinaldo or any of the other Neos in need please go to our website and check them out.  Any questions please don't hesitate to ask.  MRI is just as excited as Rinaldo to find his forever home.  Mastino-rescue-inc.org

Additional adoption info

Our rescue is breed-specific to the Neapolitan Mastiff, and while this breed is amazingly unique, it is certainly not for everyone. We want to ensure every dog's next home is truly FOREVER, so we are very careful with our placements.

* Due to same sex-aggression being so common among bully breeds, we do not place Neos in homes with another bully breed of the same sex (they must be opposite sex).

* Due to insurance and liability purposes, we do not adopt to families with children under 10-years old living in the home.

* We strongly prefer our adopters to have a secure fenced yard (no electric fences), but we do make a few exceptions.

* You must own your own home (no renters, please).

* Previous guardian breed experience is strongly preferred

We are a foster-based rescue, and our dogs are spread out across the USA, so we do not have adoption events.
