This is puppy love at its best.

In the video above, watch how an adorable golden retriever puppy reacts when its older dog friend starts whimpering in its sleep.

"I caught my new puppy comforting my older dog during a bad dream," the dogs' owner wrote in a caption accompanying the clip. "They are quickly becoming new friends."

The video, originally uploaded in March, went viral this week after being posted on Reddit. It has been viewed more than 1.2 million times so far.
