Now, that's a loyal pal.
In this very sad, yet heartwarming video, a sick-at-heart pooch is 'mourning' the death of a beloved but unlikely friend: A beaver named Beavis.
According to YouTube user "Jack Bdead" who uploaded the video, Beavis and Bella the dog had played and lived together "for quite a while" before Beavis died last year.
"Bella has been in mourning for hours," the YouTuber said.
"I love it when even animals show their love for other," wrote one YouTube user on Friday after watching the clip.
"Aww, it went from cute to sad and then touching. It's a wakeup call to cherish life," wrote another.
