Amazing doggie noses!

What's that I smell?
You met a poodle? Mom!!!
Most people communicate through hearing, seeing, and smelling, in that order. Dogs do it the other way around; smelling, seeing, and hearing. A dog's brain is one tenth the size of a human brain, but the part that controls smell is 40 times larger than a human's. 

The average dog's sense of smell is about 1,000 times better than a human's. We have around five million scent-detecting cells, and depending on the breed, dogs have between 125 million and 300 million. The average dog has somewhere around 220 million. 

So, what does that really mean? Well, a dog can smell what someone ate, where they have been, what they touched, and what mood they are in. Dogs can smell if someone is pregnant, or of someone has cancer. Trained dogs can identify lung cancer through smelling a person's breath.

When a dog smells a tree, someone's foot, or a chair, they get an entire story. I might smell pasta, and the dog can smell each individual ingredient. Isn't it amazing?

Some dogs are trained to smell dead bodies under water. They can smell where termites are hiding, or natural gas buried under 40 feet of dirt. 

The Bloodhound is usually pointed out as the dog with the best sense of smell, but it might actually be the Beagle.

  1. It is amazing but Mom says that does don't find smells offensive like humans do, not sure why that is. Sometime it would be fun to trade noses with Mom for a day but I would probably be lost and she would be overwhelmed! Dogs and smell is so interesting!

    1. I often wonder what my dogs smell when they sniff stuff. (I sometimes think the ickier the smell to a human, the more interesting to a dog, LOL!) It would be fascinating to be able to experience the world through the other's senses, but I don't think I could do it for a day. I'd settle for a few minutes. ;-)
