Special Notes

Please note that the Neapolitaian Mastiff is not suited for everyone. Please fully educate yourself about this breed prior to adding one to your family to ensure you are able to provide life long commitment both physically and financially. This breed does drool. They are prone to cherry eye, bloat, hip and joint issues. All dogs originate from wolves (Canis Lupus). Each breed of dog was originally created by mixing different breeds together in an effort to bring forth certain characteristics. Once a breeder has created acceptable “breed characteristics” within their bloodline and these “breed characteristics” have shown to be reliably reproduced in the offspring for three (3) generations, the bloodline may be upgraded from the category of “foundation stock” to “pure-bred”. The same “pure-bred” breed standards vary from different continents, countries, territories, regions, breed clubs, and canine pure-breed registries depending on the goals of their breeders. Dog DNA testing companies can have accurate results for a specific bloodline of a small colony of dogs. However, there are tens of thousands of different bloodlines in the world which have not yet been tested for marker baseline results by Dog DNA testing companies as of 2017. For this reason Dog DNA testing companies do not guarantee the 100% accuracy of their breed lineage results and will also show different marker results for the same pure-bred breed in different continents, countries, territories, regions, breed clubs, and canine pure-breed registries depending on the goals of their breeders.
