Don't get near me: A dog that is afraid will often times show an aggressive attitude toward his opponent. A dog will show this behavior by putting his ears back and opening his mouth, he will slightly put his lips up so his opponentcan see his teeth, his head raised, his eyes fixed on the opponent ready to attack if it were necessary. This type of expression is usually accompanied with loud deep barks to tell his aggressor to leave or suffer the consequences.
