I was watching a nature show with them the other day thinking that those marking would be beautiful on a dog breed. Off the top of my head a dutch shepherd, they have a brindle coat and prick ears. But they are not a dog for most people, very high drive dogs. I don't know of any breeds that have that splotchy calico coat. But more important you should never pick a breed solely on looks. Personality is so much more important.
The closest I saw with a quick search is a 'calico' lab, but he is suspected of being a chimera. Very pretty dog though.
I don't know any specific breed that looks like these.
the closest you get are probably shorthaired Merle dogs (like some catahoula for example).
generally I'd suggest rather searching one that fits you in temperament than one that you just like by looks.
I love the way a Dogo Argentino looks for example... but I'd still not get one since it doesn fit my lifestyle.
Sorry if this sounds mean but getting a dog because it looks pretty/like a wild animal is a bad idea. Even if you find a dog that looks like that, it might completely clash with your lifestyle. There are many beautiful or exotic looking dogs that get purchased because of "looking cool" and then their owners quickly discover the only thing they like about the animal is the appearance. Then the dog ends up in a shelter.
