“This is Otis at 2 years old. His mother is a registered Neapolitan Mastiff; his father a registered Dogue De Bordeaux (French Mastiff). He is a very easygoing dog that loves people, other dogs and cats. He doesn't like traveling too much and he gets occasional ear infections due to his droopy ears, but he is such a character, especially when he wants to play. He runs around with our other 3 dogs—a Lab / Malamute, Chihuahua and Shih Tzu / Chihuahua."

  • Neodeau Mastiff

The Ultimate Mastiff is not a purebred dog. It is a cross between the Dogue de Bordeaux and the Neapolitan Mastiff. The best way to determine the temperament of a mixed breed is to look up all breeds in the cross and know you can get any combination of any of the characteristics found in either breed. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generation crosses.

Ultimate Mastiffs, Rogue and Zeus—"This is Rogue and her brother Zeus. They are 3/4 Dogue and 1/4 Neo. Rogue has just had her first litter of pups to our pure Dogue "Rock" and her litter has come out with some stunning and rare colours including 3 traditional reds, 2 liver/chocolate and 2 lilac/isabella pups.
