Facial expression in the dog Some dogs express their feelings on their faces where we find that there are dogs smiling, and this indicates enjoyment to spend a wonderful time. As for the fearful dogs, we notice that their ears are back and asleep with the dog's eyes withering away clearly and its inability to look at its owners or focus on something specific, The dog is also in complete contraction in fear and may urinate on himself or run away if given the opportunity to do so.
