People are always around walking dogs, and playing with them in the park. You may see a dog white in your dreams, a dog with rabies, a dog wolf, a dog walking, or a dog eating dog, and each of these has its own particular meaning that can only be discovered and interpreted through dream interpretation.
If you have a dream about a dog eating dog then this means that you are embroiled in a fierce competition. Competition is what you are worried about right now and it is the main thing on your mind. This is what is most important to note. Be ready for anything to happen and be ready to face danger if necessary.
