Do Neapolitan Mastiffs shed?

Moderate shedding

Neapolitan Mastiffs shed a moderate amount — noticeable but manageable with regular brushing. Expect heavier shedding in spring and autumn as they blow their coat. A weekly brush reduces the hair in your home significantly. Not the breed for anyone with severe allergies, but most people manage fine.

Are Neapolitan Mastiffs good with kids?

Not ideal with small kids

Neapolitan Mastiffs can be hit or miss with young children. They tend to do better with older kids (8+) who know how to approach dogs calmly. Their stubborn streak can make them less tolerant of unpredictable toddler behaviour. They can be wonderful companions — but early socialisation and teaching children how to interact with dogs properly is essential.

Are Neapolitan Mastiffs good with cats?

Strong prey drive

Neapolitan Mastiffs have a strong prey drive and will often chase cats. Given their size, this can be dangerous for a cat. It\'s not impossible to have a Neapolitan Mastiff and a cat together, but it takes careful management — separate spaces, slow introductions over weeks, and never leaving them unsupervised until you're absolutely certain they're safe together. Some Neapolitan Mastiffs raised with cats from puppyhood learn to coexist, but the prey drive is rarely fully extinguished.

Are Neapolitan Mastiffs easy to train?

Challenging to train

Neapolitan Mastiffs are honest work to train — they have an independent streak and won't follow a command unless they understand why it benefits them. The stubbornness is real: they're not stupid, they just have their own agenda. Patience and consistency are non-negotiable. Short sessions with high-value treats (think chicken, not dry kibble) get better results than long frustrating drills. Puppy classes are strongly recommended — not because they need it more than other breeds, but because early foundations make life significantly easier.

Do Neapolitan Mastiffs bark a lot?

Quiet breed

Neapolitan Mastiffs are a quiet breed — they rarely bark without a good reason. This makes them an excellent choice for flat or terraced-house living where noise is a concern. They might bark to alert you to someone at the door, but sustained, excessive barking is uncommon. Neighbours tend to be fans.

Are Neapolitan Mastiffs hypoallergenic?

Not hypoallergenic

No — Neapolitan Mastiffs are not hypoallergenic. They shed medium amounts of hair and dander, which is the main allergen trigger for most people. If allergies are a dealbreaker, consider a Poodle, Bichon Frise, or a Poodle-cross (Cockapoo, Cavapoo, Labradoodle) instead — all produce much less dander.

How much exercise does a Neapolitan Mastiff need?

Neapolitan Mastiffs need 30–45 min/day of exercise daily. They're a relatively low-maintenance breed in this respect — shorter walks suit them fine, and they're perfectly happy with a relaxed routine. Good for owners who can't commit to marathon exercise sessions daily.

Mental exercise matters as much as physical. A Neapolitan Mastiff with a bored brain will find its own entertainment — usually involving your sofa or your shoes. Training sessions, puzzle feeders, and nose-work games all count.

Neapolitan Mastiff health problems

Like all breeds, Neapolitan Mastiffs are prone to certain conditions. Knowing about them upfront means earlier detection, better outcomes, and fewer surprise vet bills.

As a giant breed, Neapolitan Mastiffs are particularly susceptible to bloat (GDV) — a life-threatening condition where the stomach twists. Learn the signs: unproductive retching, distended abdomen, restlessness. It requires emergency surgery. Feeding two smaller meals rather than one large one helps reduce risk.

  • Hip dysplasia. Common in larger breeds, causes arthritis and mobility issues. Check parents have been hip-scored.
  • Elbow dysplasia. Similar to hip dysplasia, affects the front legs.
  • Obesity. The most preventable health problem across all dog breeds. Keep them at a healthy weight.
  • Annual vet checks. Catching problems early makes all the difference.

How long do Neapolitan Mastiffs live?

Neapolitan Mastiffs typically live 7–9 years. Unfortunately, giant breeds have significantly shorter lifespans than smaller dogs — the toll of maintaining such a large body accelerates ageing.

Lifespan is heavily influenced by weight management, exercise, genetics, and access to regular vet care. A Neapolitan Mastiff at a healthy weight, with good genetics and regular check-ups, will typically live toward the top of that range.

How much does a Neapolitan Mastiff cost in the UK?

A Neapolitan Mastiff puppy from a reputable KC-registered UK breeder typically costs £1 500–£3 500.

If you see a Neapolitan Mastiff puppy advertised for significantly less than £1 500, be very cautious. Low prices are the most common red flag for puppy farms.

The purchase price is just the start. First-year costs typically include:

  • Vaccinations: ~£80–120
  • Neutering/spaying: £200–400 depending on size and vet
  • Microchipping (mandatory in UK): ~£20–30
  • Bed, crate, leads, collar: £100–250
  • Food (per year): £400–£1,200+ depending on size and diet
  • Pet insurance: £75–£160/month (see below)
  • Routine vet visits: £50–200/year

Total first-year cost beyond the puppy price: typically £1,500–£3,000.

Neapolitan Mastiff pet insurance

Pet insurance for a Neapolitan Mastiff in the UK typically costs £75–£160/month for comprehensive lifetime cover.

Lifetime cover is strongly recommended over cheaper time-limited or maximum-benefit policies. Once a condition is diagnosed and treated, lifetime cover continues to pay for it every year. Time-limited policies exclude it after 12 months — exactly when chronic conditions become expensive.

Compare quotes from Petplan, ManyPets, Waggel, and Animal Friends — all have strong reputations for actually paying out claims. Always check the annual limit (aim for £7,000+ per condition) and whether hereditary conditions are covered.
