When talking about black and %of white it really depends. I'm not a elpresa follower. I go by fci standards. An black more than a white blaze white on toes or chest is wrong to me. I used to go by presa standards but learned quicly breeders that bred to that standard dogs have no type. There should be uniformity in any breed like rotties an such. I started noticing that every dog on elpresa looked different like a bunch of different breeds. An they brag about working but those guys never come out an work. So I've came to believe black too much white an no type = impure. Remember just because it looks like it an bites likes. Dosent make them pure. Take a look at some of curtos dogs. An tell me you don't see the neo influence. Impure
