Description of puppy's sensitive sense of smell

The puppy's sense of smell is amazing. They have hundreds of millions of olfactory receptor cells, which can detect and identify trace odor molecules in the air. The dog's sense of smell has high sensitivity and adaptability, which enables it to detect smells that humans can't detect, including potential food, potential partners, potential threats and so on.

The olfactory sensitivity of puppies is hundreds or even thousands of times that of their primate relatives, such as humans. They can sense the emotional state of human beings through the sense of smell, and even detect some human diseases, such as diabetes and some cancers. The dog's sense of smell plays an irreplaceable role in searching for missing people or prey buried underground.

Moreover, the puppy's sense of smell is highly selective. They can distinguish different smells, even small changes in different smells. This sense of smell makes puppies show amazing abilities in many fields, such as search and rescue, drug detection, archaeology and so on.

Generally speaking, the puppy's sense of smell makes it a very talented animal, and its sense of smell has brought us great help both in daily life and in professional fields.
