I really don't think that the black and tan Bull Terrier and the English Bulldog posted is from outcrossing with a rott in the 80's.
What about the b and t New Guinea dog?
There are also black and tan chihuahua,the color must come from rott crossings?

They were. As were boxers, dogues, am staffs, boerbols and god knows what else.
They can have white on the chest or not, either way is fine. The white is not supposed to be huge like a tuxedo pattern. As for the statement that Shauna made in that comment, I believe she is referring to the comparison of hyper type vs a great example of the breed who has the points. Given those as one's only options I agree, I would use the pointed dog as well over the boxer type that she is referring to. However, given a third option of a great Corso with out points or a hypertype dog, who has the structure, bone, type and temperament it is a no brainer
Considering the small gene pool, I would not be surprised if outside genetics were brought in to shore up the first dogs. I think there is some evidence of this, but I think it’s limited. I think the Rott and Neo would be an excellent choice to do this as both those breeds have their foundation in a common ancestor as the Corso. The Rott would bring solid working structure and the Neo would reinforce the mass. Am I freaked out? Nope. Adding a little here and there is the process in every recovery/recreation of a breed. They were doing the same thing, at the time, in Italy. I’ll talk about what I learned personally, under the second wave.
Realizing there is a little something, something in the wood pile can be very disturbing. Especially if we are new to the recently recovered breed process. But these are the facts and really they aren’t too bad. We just need to pay attention to those traits that are not Corso and breed away from them. If you throw a puppy with a rocker jaw, maybe you need to go find a line that was in the first or second wave to get a square jaw back. If you end up with a bunch of black and tan, parallel plains heads, maybe you need to go hunt up a balanced modern Corso to help with that. We are not in a place where we can pretend we are not just a couple steps up from reconstruction. We are not in a place other breeds are and won’t be for a hundred years. A good breeder will embrace the truth and work towards balance, breeding for solid Corso traits and away from other influences.
If you knew me or anything about the lines I have you would know how very far from that I am .
[video=youtube_share;nbyEBeWw-PI]http://youtu.be/nbyEBeWw-PI[/video]She is a Sicilian Cane Guzzo, and her "out crosses" are Sicilian based Maltese and Branchiero (which can throw Black and tan and always have, like other Alano types) types. She works all day long. She is small for most people here but hell, how effective is a large boney dog on a farm? She is a tightly line bred for(PIG) farm work.
