Fortune-telling of smelly dog _ What does smelly dog mean?

Why do dogs smell very strong and smelly when they don't take a bath for two days?

Dogs are animals, and body odor is a basic skill for them to survive in nature. The spread of body odor is a warning to violate their sphere of influence, a way of self-protection and an expression of courtship of the opposite sex. The dog's skin has no sweat glands, and the smell is generally emitted by the sex organs and anus, and the body odor is relatively large. Need to consider whether it is estrus or illness.
