Your own values and intentions will enable you to go forward in the world and succeed. If the dog is vicious and/or growling, then it signifies some inner conflict within yourself. It may indicate betrayal and untrustworthiness. If the dog is dead or dying, then it indicates a loss of a good friend. Alternatively, it represents a deterioration of your instincts.
That makes for some cheerful reading.
