Well I read a lot about the molloser breed and have found multiple sites saying this breed is unsurpassed as the hands down best hunter ever blah blah blah...so this may be true butttt since there is a couple kinds of these breeds which this is stated i wanted to know from someone who may know or think they know which it actually is...I've seen and watched videos of...Argentine Mastiff, Alano Espanol, Cane Corso,. there's obv. many more but these are the ones I've heard are extremely good i know about the American bulldog but what Ive read it isn't close to these other breeds. I'm going to say the Argentine mastiff because it is my favorite dog breed, but that's opinionated, which is why I'm here ha...and i mean the TRUE breed, not a pure bread dog that was based on looks i mean the TRUE pure bread dog that his single purpose is the hunt not the shows and second use is hunt.
