You can fill out an adoption application online on our official website.Miss Anita found herself abandoned in her owners garage went they moved.  Several neighborhoods around her rallied to help her.  Finally, a couple took her in to try and get her the right home on social media.  When that didn't work they came to Mastino Rescue, Inc., to help and find her a home.  She has been spayed and on 8/13/24 she had her cherry eye surgery removal.  Anita is a great girl, loves her male foster but it took a couple days for her to warm up to her female foster.  She will need time to settle into a new home.  With slow introductions she started playing with her male foster Neo brother.  If you are looking for a beautiful tawny girl, have the time/patience for Anita please go to our website at Mastino-rescue-inc.org and complete a family profile.  Anita is being fostered in Arizona but to the perfect home transportation assistance can be provided.  Visit this organization's web site to see any additional information available about this pet.November 5, 2024, 10:33 am

House-trained, Spayed or Neutered,
Story
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  Visit this organization's web site to see any additional information available about this pet.October 13, 2025, 5:57 pm

Livia

Neapolitan Mastiff

Female, Adult
St. Louis, MO
Size
(when grown) Large 61-100 lbs (28-45 kg)
Details
Good with dogs, Not good with cats, House-trained, Spayed or Neutered,
Story
You can fill out an adoption application online on our official website. Our Royal Mastino, Livia, is doing well in her experienced foster home, but continues to dream of a family and home of her own.  Princess Livia (as she prefers to be called) is a fit 3 years old typical strong willed female Neapolitan Mastiff. She balances out her play time with heavily snoring napping. Preferably somewhere with a soft bed or thick blanket. Livia is housebroken and crate trained, though she will give you side-eye if the crate contains insufficient treats to lure her in. She is indeed a princess. Her ideal home would have a large male dog to play with and a fenced yard. Livia loves to patrol her yard snuffling and watching for anything new going on in her neighborhood. She is learning there is enough food and human attention in her foster homes so that she doesn't need to resource guard. She loves belly rubs, rump scratches and neck wrinkle massages and doesn't hesitate to request them from her favorite people. Due to her forward attitude and roughness Livia needs to be the ONLY PET in the household, NO EXCEPTIONS.  She is learning leash manners as she is very strong on the leash when distracted. Livia is a lovely girl that bonds quickly with whomever she claims as her person.   Visit this organization's web site to see any additional information available about this pet.October 17, 2025, 4:53 pm
