I've seen this breed / breeder in the past and written them off. Let's get this out of the way up front: This brings to mind two words: "Bad" and "Breeder." My aversion to the long cropped, rapidly wiggling tail on the Cane Corso and the Boerboel, and my strong attraction to nice short cropped ears, however, got me to look at this breed again.
This is a North American Mastiff, a breed that was produced by supposedly mixing seven Mastiff breeds. Just which seven seems to be a proprietary piece of information.
Males are supposed to be like 120 - 180 lbs. No mention is made of height, unfortunately, but one could make guesses.
Major misgivings:
They place, seemingly, ultimate importance on color. Maybe that's not completely fair. They had to get the breed to produce true to type structurally, and in one video I just watched from them, they say they had to nail the structure first (before focusing on color

)
The price! Get this: We're talking from $3,000 to $10,000!! That said, I was told they are selling two unpapered (why?) solid color pups for $2500. So, solid color pups are less valuable to this breeder. Solid color is actually what I would want!
They have all the dogs tied out to trees. Now, I don't automatically and necessarily mind that – unlike a lot of people; but it does impart a sort of dirty, careless, unprofessional feel to the operation. Where else do they cut corners? Inbreeding perhaps??
No health testing to my knowledge. No talk of it at all.
In one video, the dog takes a dump and she keeps the camera on it the whole time. The dump is soft-serve. I would feel obligated as a breeder to him and haw and explain why the stool is so loose. I currently have a dog that has chronically loose stools and I do not want it again!
Some of these dogs' structure is not good to my eye – a big old hump of a hip/croup area. Their movement in some cases gives me pause. This was most noticeable to me in a video of some pups. One in particular, I actually question if it's got a real problem.
The tail, although I call out as a positive, seems too lightweight somehow – the half of it toward the tip seems to wag around kind of whispy and curls. I'd prefer a tail that seems more solid and hard. Yes, you can gather that the tail of a dog matters a lot to me. It communicates to bad guys.
One of the dogs is very cowhocked. This is called out as a fault in the breed standard, but it sure appears on this dog and is proudly displayed in videos, and I think it's one of their breeding females.
Positives:
Again, nice cropped ears and a full tail to keep it from being stupid wiggly.
Great size for what I want – I'd be almost certain to get a dog of about 130 - 150 lbs. That's nice and big. I figure if I don't have a dog that actually possesses good protection capability like a working Doberman, then I want size! With the Corso, I'd probably get a dog of at least 110-115 lbs., and maybe up to 130. With a Boerboel, I would be worried about getting a dog that is too heavy. I don't want a 165 - 190 to 200 lb. dog!
Intimidating, strong looks.
Supposedly a good guardian and good with kids. In the videos I've seen, I have actually been very pleasantly surprised with these dogs' alertness. I would not expect this alertness from a lot of the Mastiff breeds.
The pups and dogs that I've seen look active and playful.
The breeder is a closer drive to my house than Oji's was.
