A dog appearing in your dream often signifies qualities like intuition, loyalty, and protection. It points to your strong moral compass guiding you towards success. The dream dog could also stand for someone in your life who embodies these traits. On another note, a menacing dog suggests internal discord or mistrust in your life. If the dog is lifeless or perishing, it could indicate the end of a valued friendship or a weakening of your natural instincts. If you dream of a dog biting your leg, it symbolizes a lack of balance in your life or a reluctance to engage with new scenarios. A bite on the hand could signify betrayal, while witnessing someone else get bitten may symbolize an act of disloyalty by that individual.
