Warning: This itty-bitty pup may be small, but his leviathan ability to melt hearts and induce spontaneous cooing sounds should not be underestimated.
Redditor "Weaknesses," who uploaded the tiny dog's photo on Monday, said he met the palm-sized pup while sightseeing in Mexico City. The mini pooch had apparently been "with a nice man" when he was spotted.
"So-tiny-and-cute-can't-handle-it-aaaaagghhhh," wrote Reddit user "tamarijp" in response to the priceless snap.
We couldn't have put it better.
While the authenticity of this photograph has yet to be verified, this isn't the first time that teacup-sized pups have squeezed our hearts with their cuteness.
Last year, Mini, a teensy-weensy puppy the size of an iPhone, was dubbed Britain's smallest dog by her owner. Also last year, a diminutive terrier in Poland made hearts melt after a video of her whirling about in excitement went viral.
