Tao, a 10-year-old blind golden retriever just got a new friend. Another puppy! And not just any puppy, but a puppy named Oko who helps him get through the difficulties he's facing due to his blindness. Tao has been on Instagram for a while and has more than 14 thousand followers, but suddenly, a few months back, a new dog, Oko, started appearing in almost all of his pictures - out on walks with him, sleeping with him, eating with him, and generally looking like he's helping him navigate life more easily, and we think it's one of the most adorable things in the world.
