If you're a dog owner who loves your dog but hates being licked, you need to toughen up and just let your pup lick all they want -- because it's good for them. A vet tech named Gabby, who posts videos of her dog Winston on TikTok, explains that dogs not only lick their owners as a natural way to express affection, but they also do it because it "releases endorphins" that can help soothe a dog to sleep. She said it makes the dog feel safe and secure.
