In this way they stimulate them to breathe and how they are born when they are born, so it is very important for the survival of puppies. In the wild and in domestic dogs you will find that you will still have that instinct. The more subordinate members of a package will be the more dominant members and that is important in maintaining the package hierarchy.
Dogs also lick because they are the owners of a salty skin and out of habit. Usually it is a sign of affection among domestic dogs.
Licking releases pleasant endorphins that give you a feeling of comfort and pleasure. If licking your dog is purely a sign of affection, this is to ignore licking. Licking never gets attention. If you can, you immediately get up and walk to another room. You want to teach your dog that licking means that the person will leave the room. When you pet your dog, when he starts, the petting stops and you walk away. The licking stops with repetition.
If a dog licks itself chronically, it may be that he is bored, anxious, has skin problems such as allergies, or can have pain in his body. You must ensure that your dog gets enough stimulation and exclude any infections or allergies by visiting your veterinarian.
