[quote=johan]Why pay a lot for a mutt, when there are breeds like the Dogo Canario, Cane Corso... that have similar origins ?[/quote] No doubt the AmBullNeo has a lot going on, and could potentially be no better than a mutt. I won't make any judgement on whether it is or not, but it appears the breeders are at least breeding for utilitarian purposes. The Cane Corso is largely a designer dog, and the Presa is a far cry from what it used to be. The Presa basically satisfies the desires of the buyer who can't decide betwee an AmStaff and a Rottweiler.
