Neapolitan Mastiff Breed Information

Neapolitan Mastiffs are amongst a group of breeds classed as ‘Category Three’ by The Kennel Club. These are breeds of dog that have been highlighted as having visible conditions or conformational issues that can cause pain, discomfort or health issues due to exaggerations. This means that these breeds of dog have been bred over many years to look a certain way but that these changes to the way they look have started to cause them health problems.

Neapolitan Mastiffs are a member of the ‘Working’ breed group. Working breed dogs were bred to become guard and search and rescue dogs. Breeds in this group are specialists in their work.

Neapolitan Mastiffs are loyal, devoted dogs that love family life. Grooming is minimal, and brushing once a week is generally all that’s needed to keep the coat in good condition. Their skin folds will need daily cleaning.

Breed-related health problems:

Although some of these health problems are manageable, it’s been identified that it’s in the best interests of the dog to try and selectively breed to decrease the characteristics which cause the health problems.

Some of the characteristics and associated health problems you’ll want to know more about in relation to Neapolitan Mastiffs include:

  • Eyelid problems – such as entropion and ectropion – occur in Neapolitan Mastiffs due to excessive skin over the face and eyes. This skin causes the eyelids to droop either downwards, or in towards the eye, where the skin rubs and irritates the eye, causing problems.
  • Cherry eye – eversion of the nictitating membrane or ‘third eyelid’ generally occurs in younger dogs and can be surgically corrected.
  • Gastric torsion or Gastric Dilation Volvulus (GDV) – occurs in large, deep chested breeds such as Neapolitan Mastiffs. The stomach fills with gas (bloat) and can twist around on itself. This most commonly occurs after they have eaten. If your dog shows any signs of bloating, vomiting unproductively (trying to be sick but nothing being produced) or if you are worried they could be bloated you should speak to your vet straight away – this condition requires urgent veterinary attention.
  • Dilated cardiomyopathy – is a degeneration of the muscles of the heart meaning the heart wall becomes thinner and less effective at pumping blood around the body. The onset can be sudden so if your Neapolitan Mastiff shows any signs of respiratory distress or exercise intolerance you should contact your vet.
  • Wobbler Syndrome – cervical spondylomyopathy is a deformity or instability of the bones in the neck which results in the compression of the spinal cord and weakness of the hind legs.
  • Back Problems – Neapolitan Mastiffs can suffer from back problems such as degenerative disc disease which can cause back pain and paralysis.
  • Hypothyroidism – is generally caused by an auto immune thyroiditis causing low circulating levels of thyroid hormone. Neapolitan Mastiffs can be more prone to this condition but it can generally be managed with medication.
  • Epilepsy – Neapolitan Mastiffs can be more prone to seizures due to epilepsy and it can be harder to control epilepsy with medication in Neapolitan Mastiffs. Speak to your vet if your Neapolitan Mastiff has a seizure of any kind.
  • Cancer – Neapolitan Mastiffs can be more prone to some forms of cancer including bone tumours (osteosarcomas).

For more information about these health problems you can speak to your vet or visit the Kennel Club or The Neapolitan Mastiff Club.

For some conditions, there are screening programmes available through the British Veterinary Association (BVA) and the Kennel Club. The Canine Health Schemes allow breeders to screen for a range of inherited diseases, so it’s a good idea to check the parents of any puppy you’re looking to rehome have been screened under these schemes. We’d also recommend discussing the medical history of your potential puppy’s parents and grandparents, and think very carefully before taking on a dog with any of the health conditions listed above evident in the family line.

You can find out more about the Canine Health Schemes on the BVA's website.

Exercise requirements:

As adult dogs, Neapolitan Mastiffs need around an hour of exercise daily, but shouldn’t be over-exercised as puppies when their bones and joints are still developing. Training will require patience, but can be achieved using reward-based techniques. For more information on training your dog, take a look at our dog behaviour page where you can pick up plenty of tips to help you and your canine companion better understand each other.

Estimated lifetime cost:

The likely lifetime costs for a Neapolitan Mastiff are based on estimates calculated using current market prices and include:

The list above does not include veterinary costs if your pet becomes sick or injured, so these average lifetime costs could be even higher.
