well from hear say and hear say alone, I believe presa's are the foundation of this "new" breed. If any of the info I gained is remotely true then I would stay away from this dog. It doesnt have a standard because its too new also the word on the guy is when he was breeding "pure" presas and "pure" DDB's and "pure"neos all the dogs where coming out looking like the next breed and none of the parents were health tested. So that draws TRIPLE red flags for me and should for anyone else!
