Tuna the chiweenie won't win any beauty pageants, but the quirky-looking dog will melt your heart. Just ask the pooch's 46,000 Instagram fans, who happily heart photos of Tuna showing off his adorably crooked grin by the thousands.

Tuna's best human pal, Courtney Dasher, serves up a daily Tuna special on her Instagram account, tunameltsmyheart. "My hope is that he brings you A TON of joy," Dasher wrote under one image, "and fits of laughter with each post."

Let's hope newfound fame doesn't go to Tuna's head and he ends up signing an endorsement deal with Invisalign.

Can't get enough of Tuna's cuteness? Watch him try on shoes in the video below and prepare your face for a big smile.
