A dog's nose is a little bit different. A dog's nose is, depending on the breed of dog, probably more sensitive than a cat's nose for sense. But in that case if you want to maybe qualify a dog's nose in terms of comparing it to a fingerprint for identifying a person as to its ability to perceive scent, then yeah that would be an identifiable thing for a dog too because not all breeds have the same ability for scent, say those cats. House cats have a pretty good sense of smell. Even the larger cats, lions, tigers, things like that, extraordinary sense of smell for those animals. Trivia, just one piece of trivia for tonight.
