In this dream I was petting a small dog when he bit my index finger of my left hand. For some reason I didn't think that he would dare to bite me, so I persisted to pet him, thinking that my finger was hurting for some other reason. However, then he bit me again on that finger and I looked at it, but instead of blood I saw brown pus come out of the bite marks. I know that dreams are often symbolic and I've read somewhere that seeing a dog in a dream is a metaphor for a friend - so could this mean that I will be hurt by a friend or something along those lines? If anyone can interpret this dream for me, I would be very grateful.
