Ah yes, the dog in tarot.
The dog is a symbol of loyalty, justice, intuition, protection, guidance, the hunt, and reliability. For most folks seeing a dog evokes feelings of childhood, happiness the a great urge to pet the animal. For the rest, a dog evokes a feeling great screaming fear.
Generally the dogs of the Rider-Waite deck are benign, loyal and helpful. While this may not be the case in all tarot decks, I’ll stick with the Rider-Waite for this.
