Despite your best efforts to remain loyal to your friends and companions, you are being spurned for your fidelity. Has one of your friends recently insulted you or hurt your feelings. One reason that you might be dreaming of a dog biting you is because you feel hurt by that and want to express a reaction.
A dog also symbolizes in the dream world, the idea that your strong beliefs and ideas will be rewarded. You have stayed the course in your life and never turned your back on what you wanted to fight for and as a result you will be rewarded for that. To dream of being bitten by the dog would suggest that you may have indeed turned your back on yourself without realizing it. It may also suggest that you dedicated yourself to a fruitless cause and because of that, you are being punished. You will never reach your goals in life because you cannot control yourself or your beliefs. Try to find a better path or you will find yourself sinking lower and lower in life.
If you dream that a dog bites your leg, this suggests that in some way you have fallen off balance in your life. This interpretation could be referring to a literal physical equilibrium that you have lost or it could be referring to the fact that you have taken on some new path in life that is leading you down to an area that you do not feel comfortable with. You are being led down a path which you don’t necessarily agree with. A dream like this suggests that it may have been your intention recently to participate in a new activity to change your life around, but now you are having problems dealing with that change. It is up to you to decide whether you want to continue down that path, or whether what you are losing now is more important then what you will eventually gain for your future work. Sometimes it is a good idea to push through adversity and what is working against you in order to achieve your goals, but sometimes it can be more detrimental than it is good. You decide what you want to do.
