The dog in the dream is the guardian of the dreamer's own internal code of conduct, norms and morality, and can also be understood as the image formed in the dream when people's so-called "conscience" plays a role in the inner subconscious. On the other hand, it symbolizes friends, indicating loyal love, loyal friendship, or the power of friends.
Dreaming that a dog bites, the ominous sign is being ambushed or attacked.
I dreamed that my friend was bitten and bleeding by my dog, and my career dream was within reach! I know you have been working hard and haven't given up, so success is inevitable. You are lucky to meet new partners, or you will be appreciated for your recent work achievements. Some friends were attracted to contribute to a high-profile project.
