There are conflicting reports over the origin of the Nebolish Mastiff. Some sources state:
With over 80 mastiff types, the Nebolish is one of the rarest. It was developed in late 1960s in the Northwest and Canada. The breed was developed to increase the agility, health and life expectancy of the mastiff by crossing Old English, Bull, Dogue de Bordeaux, mastiffs, and it is suspected that the Great Dane, Boxer and Saint Bernard maybe in the bloodline. There has never been an exact breakdown of the breeding program; to keep the line pure the exact breedings that evolved to the Nebolish we know today has never been disclosed. The Nebolish ancestry can be traced back to Aristotle and Alexander the Great, who received these large dogs for soldiers* protection from lions. The Noble Loyal Healthy Mastiff is not a new breed, but a breed which was lost in history and now rediscovered in the Nebolish Mastiff.
Others say it was developed in Canada in the 1960s, by crossing the Neapolitan Mastiff, Dogue de Bordeaux, English Mastiff, Boxer, Bullterrier, Bullmastiff, Deutsche Dogge, and the Saint Bernard.
While others claim the Nebolish Mastiff is simply a cross between the German Boxer and the French Bullmastiff.
Others report the Nebolish Mastiff is a breed still in the stages of development and some even claim it to be a mix. Photos posted of Charlie (long coat - see below and Photos Page 1) could be the Saint Bernard in the lines coming out, but this is unclear.
The CKC (Continental Kennel Club) recognizes the English Mastiff and Neapolitan Mastiff cross as a Nebolish Mastiff.
To date, we have only come across one breeder of the Nebolish Mastiff.
That was the best info I could find. No matter what it would be a very very young limited "breed" and I think I would fall on the side that at this point it's really just a mix. I also could only find one breeder offering these as an actual breed and it was jade ranch also known as Whiteface Ranch
