As far as photos posted on Instagram go, they don't get much cuter than this. Tokyo, Japan-based mother Aya Sakai has been charting the adventures of her young son and his best friend, which just happens to be a French Bulldog, using the popular photo sharing app. Whether they're cuddling on the couch or watching tv on a cushion, the two just can't seem to get enough of each other. The relationship will remind you of the sweet 88-year-old grandmother and her cat, as well as Haru and Mina, those incredibly cute brothers growing up in Japan. Adorable beyond words!
