Dogs of All Sizes Look Like They're Sitting in Mugs. Collective "Aww" Heard Worldwide.

We know tiny teacup dogs exist and they're adorable, but what if every dog could fit into a mug? Through the optical illusion of photography, they can! The trick is simply to hold the cup in front of the lens with the dog off in the background. Over on Instagram, dogs of all sizes are being turned into mini versions of themselves, sitting in handheld cups under the hashtag #muttmuggin.

Fluffy little pups pop out of adorable mugs.

Serious and contemplative dogs sit in their modern, minimalist cups.

Even tough pooches have hard-edged mugs of their own.

No matter what type of dog, there's a superimposed mug waiting to "carry" them.

Even the lazy ones that don't want to get out of bed.
