Clinical signs

  • Visible red swelling in the corner of the eye
  • Excessive tear production

If left untreated, the cherry eye problem can decrease tear production and also lead to incomplete closure of the eye. It can cause severe pain, infections and even blindness in some cases.

The Mastiff has a double coat for weather protection where the outer one is short and straight, while the inner one is shorted and dense


These dogs come in a limited number of colors including tawny, mahogany, black, and gray




A short coat means that a normal bathing and brushing routine works just fine. Just the ears and eyes should be cleaned properly with a damp cloth or a paper towel. Nail trimming, just like other dogs, is a must periodically.


The younger Neo puppies are more active and are important to train at that age as the older ones can get laidback. Encouraging, positive reinforcements work well on this breed over punishments. A short 15-30 minute walk usually suffices along with hikes or a game of catch once in a while

The Neo Mastiffs are a descendent of the great Molossus war dog and their existence dates way back 5000 years ago. It also owes its ancestral origins to India as the short-hair feature comes from there. It was bred to master ‘catch’ and ‘watch’ as in catch bigger animals during chase and guard houses. Their unique physical trait is their loose facial skin and abundance of wrinkles on the entire face.

Health Risks for a Neo Mastiff Puppy

Apart from the above-mentioned common health problems, these lifesaving dogs are also prone to some other health related issues which can give the owner a hard time to their time, head and even wallet.

  • Just like any other big dog, they are prone to hip and elbow dysplasia
  • This breed is also prone to a form of skin infection called lip-fold pyoderma. The folds of skin along the lower jaw are usually moist. Due to that, bacteria and yeast can develop there and the smelly area becomes uncomfortable for your dog.
  • Osteosarcoma – a type of bone cancer is also evident in these dogs which affects around 8 to 10 thousand Mastiffs in the USA.
  • The New Mastiff is also susceptible to breathing problems because of some physical abnormalities like narrow nostrils or a small wind pipe that compresses easily.
  • There is one life threatening condition which Neo Mastiffs are prone to called Dilated Cardiomyopathy

Things to watch-out before deciding to own a Neapolitan Mastiff

There are a few cautions that you need to know before deciding to adopt a Neapolitan Mastiff

  • They may not be very great with other dogs or even your own pets at home especially if they are smaller in size as the sheer size of these dogs will scare them and can lead to aggression
  • If by chance you plan on playing tug-of-war with your Neo, make sure you win. Once, the dog figures that it has more power than you, it may no longer obey you much.
  • They can be really stubborn at times during trainings or other activities making it difficult for them to teach obedience
  • They have a mind of their own and can be very determined at times and won’t hear you or your commands
  • Do to their size, supervision may be needed around young children


Looking for a big giant but gentle dog then Neapolitan Mastiff is the one for you. A calm and not so loud dog, welcoming and easy going on strangers and other pets, a Mastiff is a keeper. And an actual keeper as well, because its size and tough look will scare most of the people away from the gate.
