I was staying on a polish kennel last weekend, and the owner showed me an old corso lady. las vegas line. She was 11 years old and had the size of a big amstaff. Her nose was quite long and the face didnt say corso in any way. More like a bullterrier kind of head. The breeder claimed, that many of the old dogs from kennel las vegas, was american bandogs. It did made sence when I saw the dog. I have heard that before, but this is the first time I se a corso, that could look like a bandogmix
