Sniffing Around
For certain things, the dog’s noses are excellent. People have five million olfactory receptors, but for dogs, they have 220 million. How crazy is that? They can smell better than we can at least a thousand times. When they sniff, they feel danger, or they are tracking the prey. They would then remain quiet when they do so. Dogs smell the distinction between dogs and people. Yeah, of course, even identical twins can be told apart!
