A part of you that is faithful, protective, a good friend, and that is loyal. Alpha behaviour. Is someone trying to overpower you? Are you having trouble with your canine teeth? Has something happened around that area of the mouth? Is there something you need to verbalize? Does someone around you have vicious tendencies that you need to watch out for? Dogs come in dreams as helpers so you can balance a situation. If it bites you, look at what area you are injured as this has significance.
