How well does a coyote smell? About 10,000 to 100,000 times better than you or I." If you make the analogy to our vision, what you and I can see at one third of a mile, a coyote could see at more than 3,000 miles away." Their long nose and brain are built for smell. They have 200 million more olfactory receptors than we do. Much of their communication is done through smell. Such as marking their territory with keep out, I am friendly, I am looking for company,and I am the Alpa dog. Recently, the German Shepard a close cousin to the coyote located four young men murdered and buried 12.5 feet deep. Their sense of smell is simply amazing. We are fortunate when we have encounters. I do use so called scent elimination sprays. However, I believe it is at most just helpful. I have called coyotes within arms length using nothing, skunk essence, skunk gland, and the elimination spray. You decide what works best for you. Anything that gives you confidence has to be helpful.
