Dogs Lick you to know about you

I was at my friend’s place who got a pet dog, whom he loved very much and they both lived like a family. He was very stressed, and we both were discussing the issues when suddenly his dog came and started licking him.

A few minutes later, the dog went and took a ball to play in front of him to make him happy. My friend told me that the dog had known about his owner’s depression and trying to please him.

This left me all surprised that what makes dogs sensible enough to feel it. So I searched for it and found some interesting facts about this.

Another reason for dog licking you superfluously can be that he wants to gather information about you. They want to explore the human world and its strengths and weaknesses.

Dogs usually sniff or lick moist areas of the body, such as hands and feet. This informs them about our health conditions even before we get to know about it.

Dogs have special receptors in their nose and mouth that enables them to interpret the scented molecules in human sweat. As mentioned above, they have 300 million olfactory receptors that are 40 times stronger than that of humans. So that makes them smell the feelings inside us.

Dogs Lick you for cleaning

“The objective of cleaning is not just to clean, but to feel happiness living within that environment.” Marie Kondo

Cleaning is essential for our health. Hygiene plays a significant role in good health, and it affects both animals and humans. There are many animals, brought up in a filthy environment, especially dogs and cats that roam aimlessly.

On the other hand, some cats and dogs are adopted as pets and live in a healthy, clean environment. This creates a sense of responsibility among the pets that helps them take care of them as well as their owners.

Dogs, living in a friendly environment, are very honest to their owners. They are like friends to their owners and look before them just like their owners looked for them on their time.

So when they see even a small dust particle or any food scraps or particles on your skin, they start licking on that part and clean it according to their senses. This is another form of affection they have for their owners by looking after them and keeping an eye on the little things.

But they don’t know that what they are trying to do is actually creating a mess for us! Although they do this out of care, but that saliva they are using for licking, itself has many germs in it. It may clean the dirt on you externally but will harm you internally in the form of bacteria.

Your Dog Might Lick you for Healing

Healing the wounds with saliva? It sounds too creepy to hear that Dog saliva is a healer for wounds. According to scientific research, even human saliva has many antibacterial and antimicrobial properties. Modern medicine has approved the saliva as an active healing agent.

A few days ago, while I was standing outside my house enjoying the weather, a boy was playing outside his home along with his family sitting near. Suddenly he slipped and fell down. There was a wound on his foot, and it started to bleed. Their family dog ran there and started licking that place of injury.

The parents, standing with him, got scared of this and shooed that dog away. However, his grandmother asked his parents to let the dog lick that wound as it will heal it faster. That left me all amazed and thinking about what is the real story behind this concept.

We have a lot of evidence from the historical traditions that dog saliva has healing properties. The city of Hardai was named as Cynopolis because they used to offer dogs in healing practices. They believed that dog licks might cure the diseases, especially those areas of the body with sores or lesions.

There are still many believers in this concept. There’s a french saying “Langue de Chien, langue de médecin,” that means, “A dog’s tongue is a doctor’s tongue.”

All the dirt on the wound will get stick to the saliva that will clean the area of the injury from all dirt and debris. Scientists have found that dog saliva has some proteins called histatins that can cure infections. Some histatins have cells called epithelium that help to close a wound quickly.

However, nowadays, advanced research has found that these concepts are baseless and are more harmful than healthy. Your dog may clean the wound area from dirt by licking and bleeding may stop, but it will transfer all the bacteria to you through that wound. Today, it is not believed to be a healthy practice!

Dogs Lick to Get Your Attention

Attention seeking is always followed by love and affection, and every one has its way of seeking love and care. Those who ask for your attention have special expectations and look for you every time they need you.

As we have mentioned above, that pet dogs live in a friendly environment. So they, just like humans, demand special care and attentiveness from their owners.

If you have been giving them a significant time of your life, daily, and for once if you get busy in your routine, they will think of every possible way to grab your attention. As a result, they may start licking you for that.

Dogs usually show such behavior when they get a positive response from the other side. That response may be in the form of touches of laughter, petting, smiles, etc. or you agree to play with them. Sometimes it’s just that your dog has got bored and that is why he is looking for your attention.

Attention may not be because your dog needs some time from you; there may be some sort of emergency that he is trying to indicate with such actions.

You may stop this quench for your attention by endowing a part of your routine for your dog or else they will continue licking you until they get the mission accomplished!
