Bears are thought to have the best sense of smell of any animal on earth. For example, the average dog's sense of smell is 100 times better than a humans. A blood hound's is 300 times better. A bear's sense of smell is 7 times better than a blood hound's or 2,100 times better than a human.
A bear's sense of smell is so acute that they can detect animal carcases upwind and from a distance of 20 miles away.
