"This is our little guy at 8 weeks old. His name is Dooley. He is Neapolitan Mastiff and Boxer and is the best of both of the breeds. We think he will look more like a giant Boxer and therfore call him a Neo-Boxer. He doesn't do very much at this stage in his life except sleep, eat, and you can guess the other. He does enjoy pouncing around with my two year old son. Only in short intervals though, and then it is back to napping on his favorite bean bag. He really is a great puppy and an excellent addition to the family."
The Neapolitan Boxer is not a purebred dog. It is a cross between the Boxer 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.
