Question: As dogs get older, their senses, including sight, hearing and smelling, are diminished.
Answer: False. Only sight and hearing, the sense of smell normally stays with a dog for a lifetime.

Question: A dog’s nose print is as individual as a human’s fingerprint.
Answer: True. Noses have a pattern of ridges and dimples that, along with the outline of the nostril openings, make up a nose print believed to be as individual as a human’s fingerprint.
Question: A dog’s sense of smell has been tested at 1,000 times stronger than a human’s.
Answer: False. A dog’s sense of smell has been tested at 10,000 to 100,000 times stronger than a human’s, an order of magnitude equivalent to one second in 317 centuries. Or is the equivalent of smelling one bad apple in two billion barrels.
Question: Dogs react in different ways to different herbal smells.
Answer: True. In tests, for example, it has been found that dogs relax when the aroma of lavender is fed into their environment. Chamomile also makes dogs calmer. Rosemary and peppermint, on the other hand, makes dogs more excited.
Question: Dogs can smell fear in humans.
Answer: True. Fear does smell in humans, as well as in dogs and other animals. When alarmed or fearful our perspiration gives off odors, as well our pheromones and hormones—all easy for a dog to detect.
Question: There is a theory that says that Man lost his sense of smell because the dog as part of his tribe, did the smelling for him, hence the two species co-evolved.
Answer: True. There is such a theory and it makes sense to us. But it hasn’t been proven yet, but because proto-dog have been around since at least 15,000 years ago, there could be validity to this co-evolution premise.
