If you've ever wondered why your dog licks you before bed, you've come to the right place because we — with the help of a TikTok-using vet technician — have all the answers you're looking for!

So, without further ado, read on to learn more about your furry friend's bedtime licking habits. Plus, stick around to hear what the internet has to say about this adorable trait.

In the viral video — which has amassed 1.6 million views— the creator, Gabby (@winston_thebeagle) showed her lovable beagle pup, Winston, licking her hand before bed.

Gabby wrote in a text overlay, "It may be bothersome to some people to be liked by your furry one before you go to sleep ... but next time you get annoyed, remember: This releases endorphins that soothe your pup to sleep and gives them a sense of security and reminder of puppyhood (of them being groomed by their mothers) and is their natural way of expressing their affection toward you and thanking you for another day of love and care."

The video brought many dog owners to tears: "I just started crying," one person commented alongside numerous heart and face holding back tears emojis. Another wrote, "Well, I'm crying now."

One person revealed that the video made them cry because they told their dog to stop licking them. Well, let's hope that from now on, their fur baby gets to give all the licks they want now for the rest of their life!

As for why the video became so popular? Gabby believes it's because "people love dogs and are always looking for a better understanding of their dogs."

However, she also highlighted that not all licking relates to affection: "Incessant licking or doing it for long periods of time may be indicative of something else, but if your dog wants to give you an occasional lick on your hand, then we should oblige as pet owners."

We don't know about you, but we're running to give our dogs the biggest hug right now!
