When your dog licks your face excessively while you're crying, it's likely due to a combination of reasons, and the exact motivation can vary from one dog to another. Here are some possible explanations for this behavior:
Comfort and Bonding: Dogs are sensitive animals and can pick up on your emotions. When they see you in distress or crying, they might interpret your behavior as a sign that something is wrong, and they instinctively try to comfort you. Licking is a natural behavior for dogs to show affection and bond with their owners.
Social Grooming: In the animal world, grooming is a form of social bonding. Mother dogs lick their puppies to clean them and show affection. When your dog licks you, it's possible they are trying to engage in this social grooming behavior as a way to reinforce the bond between you.
Salt Attraction: Tears can contain small amounts of salt, and some dogs may be attracted to the taste. While this might play a role in their licking behavior, it's not necessarily the primary reason.
Attention-Seeking: Dogs learn that licking can get them attention and reaction from their owners. If your dog has received positive reinforcement or attention in the past when licking your face, they might repeat the behavior when they notice you are upset to seek comfort and attention.
It's important to note that excessive licking can sometimes be an issue, especially if it becomes obsessive or bothersome. If you find your dog's behavior becomes too much to handle, you can gently redirect their attention to a toy or a different activity. If the excessive licking persists or becomes a concern, it's a good idea to consult with a veterinarian or a professional dog trainer to address the behavior properly.
Ultimately, dogs are empathetic animals, and their behavior when you're upset is a sign of their love and concern for you, regardless of whether there's a slight taste attraction to your tears.
