Genetic Predispositions and Health

The Neapolitan Mastiff, or Mastino, is a large, deep-chested dog that can suffer from bloat, also known as gastric dilation volvulus (GDV). This is a life-threatening condition that can come on suddenly, so it’s important to know the warning signs and get an affected dog immediate veterinary care. They are also prone to cherry eye. Mastinos may suffer from back problems, Wobbler Syndrome, osteosarcomas, heart muscle degeneration, and epilepsy. Like many breeds, the Mastino can be affected by degenerative myelopathy, progressive rod-cone degeneration, hip dysplasia, and hyperuricosuria. Genetic screening is recommended to assist veterinarians with diagnosis and proactive care, as well as help breeders identify affected and carrier dogs.

Personality and Behavior

Neapolitan Mastiffs are known for their calm and steady nature. They are very protective and loyal, making them excellent family dogs if socialized properly. Despite their size, they can be quite gentle and are generally good with children. However, they can be wary of strangers and may not be well suited to homes with lots of visitors. Early socialization and training are key to ensuring they are well-behaved and comfortable in various situations.

Despite their short hair, they do shed, particularly during shedding season. Regular grooming can help manage this and keep their skin healthy.
