That dog was bread from this kennel, www.petersonpitbull.com/ I had his mother and a friend had the father and they both came strait from the kennel from there main dog Sherman Tank who is no longer around.
Xcrispi they do have some Mastiff traits so I am not surprised that they look similar. He is about 90LB and is kind to all other animals, but is a good guard dog, but not vicious for no reason.
I have bread rott's, pits and bull dogs, and I have had a nice Mastiff.
I like the mastiffs, but they get so dang big that they need allot of room to really thrive IMO. I have had 10 dogs for strictly breeding and with litters around the clock it was really allot of work.
As far as pics, my disability is related to my vision so pics don't do me too much good, but my wify can always describe them to me and she loves dogs, we have probably over a hundred pics on file of the dogs we have bread.
Well adieu for now.
