I've been emailing mr mason a bit, he says in 16 years of crossing cats and dogos he's never had one that didn't catch. I put my name in the hat for a cross, figure if a mans been doing it that long successfully there's no sense in trying to recreate the wheel. I think if you're crossing a dogo with another BD (pit, American, or whatever) you're just breeding down. If you want a smaller cd than a dogo I'd just rescue a pit from the pound.
I agree with you 100% on the breeding down thing!
