5- Fifth Reason
They LOVE you, and that is how dogs mostly express their love! They cannot say “Thank you” or “I am sorry” or “I Love You” so it is kind of understandable! So never get upset to your dogs if they want to lick you. Have you ever thought that for your dog, you are the only thing they have in this world? You are their owner, God, mother, father and so on. Try to treat them nicely, and allow them to express their feelings!
