Dog licks because its the only way to express itself with people their own breed . He does it in the morning and as a greeting . he does it for quite some time and is very determined with it. Interesting subject and there’s many theories. Of course, the answer I’m providing doesn’t specifically answer this because Dog Licking Human Faces is universal to all dogs – no matter what breed or Sex. Dogs lick for a lot of reasons. Licking is a submissive social signal, first of all, allowing dogs to show deference to dominant “pack members.” Puppies lick to solicit solid food from their mothers when they’re weaned, so a young dog may lick to request its dinner. Some dogs lick as a substitute for puppy mouthing behavior. They’ve been trained not to put their teeth on people, so they lick to occupy their mouths. Licking may be a sign of affection, your dog’s way of showing you that he’s enjoying spending time cuddled on the couch with you. Or, he may just like the taste of your soap!
Though it’s usually harmless, licking can be a problem if carried to an extreme. All dog lovers have seen how a dog greets either its owner or another dog by wagging its tail, pulling its lips back in a grin or licking the face of the welcome friend.”
The licking of the face is an intriguing gesture, coming directly from the instinct of the wolf. When the mother wolf has returned from the hunt, her pups will lick her face to stimulate the mother to regurgitate food for them. In this way, they are weaned from milk to solids. Little do most dog owners know that when their dog gives them a kiss on their return home, it is actually asking them to regurgitate some food!”
I know that face licking is usually more vigorous than other licking purposes, but is there anything a dog will not lick? In addition to their own parts and our faces, I have seen them lick toys, walls, carpet, rocks, and dirt. With this in mind, I think we can lower our requirement for a reason why they lick our faces. I would say a combination of cleaning instinct (they do the same thing to puppies, sometimes for a very long time), a standard greeting, exploratory purposes (mouth and toungue are their primary method of manipulation, and a nice salty human face should leave us asking why a dog wouldn’t want to lick people. Dogs like salt, as do most animals, and perhaps this is why they lick your face. I know that my dogs will lick my bare arms and legs in the summer.
The other reason could have to do with regurgitating food as posted by someone else, but I’m not sure on it.
