American Bully Dog's Rare 'Marbled' Eyes Are Almost Too Stunning To Be Real

Did you know most dogs have brown eyes? It's true, and those puppy dog eyes sure have a way of making us fall in love. This fact is also why spotting other eye colors in dogs can be so striking, like the dog breeds with beautiful blue eyes, like a husky, for example. Now, you can see both unique colors and shapes in one with this viral TikTok video in which one American bully's marbled eyes are almost too stunning to believe.

Enzo's eyes are unbelievably unique. So much so that one previous viewer assumed their marble effect was the result of some sort of filter or ring light reflection. Enzo's mom made sure to highlight the absence of ring lights in the minute-and-a-half outdoor clip before showing off her hazel eyes, for reference. Then, the big reveal: Enzo's marbled brown and icy blue irises.

Many viewers took turns sharing what Enzo's eyes reminded them of. While some noted the peppermint-candy like pattern of his eye colors, one harkened back to classic "marbles back in the 70s." The main thought that echoed throughout the comments was that one could easily "stare at his eyes all day." We totally agree!

Enzo's gorgeous eyes are sure to brighten your day. Though they might seem unreal, they're actually the result of a very real condition called heterochromia. It's when someone's eyes are different colors, and it can occur in both humans and dogs (though it's more common in canines due to selective breeding). So how exactly does heterochromia occur, and does it affect a dog's vision?

Congenital heterochromia, like what Enzo has, is a genetic mutation caused by a lack of melanin in all or a certain part of the eye, and it has three types. You may have spotted pups with one blue and one brown eye. That's an example of "complete heterochromia," or when each iris is a different color. Then there's sectoral heterochromia, which means just a part of a pup's iris is blue. Finally, though, is what Enzo has: central heterochromia. It creates that sort of marbled view of multiple colors in the iris.

Now, if you're wondering about dog eyesight when it comes to heterochromia, there's good news. Though a common belief ties two different eye colors to blindness, this condition doesn't seem to affect a dog's vision, especially if it's congenital (something you're born with). Also, outside of Dalmatians with heterochromia noted for having a higher risk of deafness, the condition isn't known to cause any related health problems in other dogs.
