Internet - At first, this puppy wasn't too sure how to react to a little peck on the cheek from its owner Abby. What it decided to do next melted plenty of hearts on the internet.

The video posted by Reddit user abbynormalisrelative went viral, with over 140,000 upvotes and lots of delighted comments. Even though it's only a few seconds long, there's so much cuteness packed into it.

Abby's description set the stage: "Kissed my best friend to see what would happen". She's lying on the bed next to the tiny pooch and goes in for a little smooch. The fluff ball looks a bit confused at first, giving the camera a quick look while deciding what to do next.

But then it reacts in the most adorable way – with a little peck of its own!

Abby is overwhelmed by the love and almost can't believe what just happened. 

Reddit users are getting a warm fuzzy feeling inside too. They've been showing their appreciation for the video: 

• "Pup's like 'what just happened? Did I just get kissed?! Gotta kiss back!'"

• "That side glance before kissing you back killed me! Super cute pup!"

• "My heart can't take it! That was the sweetest reaction!"

Abby's dog is now a real internet star, as people play the charming clip on repeat.
