This is the main point of difference between the two species.

Wolves have the habit of greeting their fellow beings with excessive licking on the face. Dogs too, exhibit similar actions. They also greet their co-fellows by licking their faces. In spite of similar traits, the difference between both the animals cannot be overlooked. Wolves are completely non friendly with humans and dogs are a man’s best friend.

These actions are positive signs of friendliness seen in a dog. The dog is completely harmless if they show such symptoms. Dogs have instincts, which are unmatched and unparalleled.

Science has revealed their ways of expression and conducted many tests to understand the behavior of dogs. Though their ancestors belonged to the species of wolves, they separated due to their instincts. They were more superior in terms of wolves as far as their association with humans was concerned. Thus dogs became very friendly with humans because they related better with humans. The dog’s behavior with humans was more secure than other animals. Wolves became dangerous for human and hence man too is loving and caring towards them. They want to maintain a distance with wolves because wolves are ferocious and harmful unlike dogs.

These are the primary reasons of the love for humans, which dogs have in them instinctively. Even humans have reciprocated their love for the dogs in very friendly and secured way. We can conclude very safely that dogs are our best friends. They only want love and affection in return and emote in a similar manner.
