Why does my dog lick me so much?

It’s a sign of affection

Dogs lick as a greeting or to comfort you. Dogs get licked as puppies by their mother to clean them so they associate licking with showing affection and care. A dog loves licking as it releases endorphins and creates a network of positive reinforcement between it and its pet parent.

They like the taste

This may sound odd but you just might taste good to your dog. According to the Kennel Club, a dog’s sense of taste may be particularly attuned to want to taste our sweat for its salty and acidic qualities. A dog’s sense of smell might also catch the odor of something you recently ate when licking your face.

They want attention

Just as licking may be a dog’s way of showing affection, an attention-seeking dog might lick you to get you to cuddle up to it or pet it. A dog feels emotions similar to humans and often seeks the attention, love and care of its owner.

It is anxious

Although it is a rare phenomenon, dogs can get obsessive-compulsive disorder and excessive licking may be a sign of it. You can try to curb your dog’s behavior and get it to stop obsessively licking you by allowing it to expend energy on positive activities such as taking a walk or doing its dog training exercises.

If your dog is partial to behavioral issues or extreme separation anxiety and also tends to lick when anxious, it might be worthwhile to speak to a vet or a behaviorist on the subject.
