The focus series looked at cats last week. Dogs insisted it’s their turn this week.

Here are some fun facts about the puppy and other dogs as well. Leta’s nose print is unique to her. Just like your thumbprint is to you. No two dogs have the same one. What her nose does share with most other dogs are some 150 million olfactory receptors. Humans have around 6 million. That’s why their sniffing ability far exceeds ours. Some dogs have a lot more. The blood hound is top dog with around 300 million. They can follow tracks several days old and can stay on a scent trail for over 100 miles. Their sense of smell is so well documented that it can be admitted as evidence in a court of law. “Sniff, sniff. Woof, woof, woof!” Translated: Number three in the lineup robbed the bank.

While we are dealing with a dog’s sense of smell, here’s a fact I didn’t know. They have a back up system for ‘smelling’ pheromones (chemicals) that contain a great deal of information. It’s called Jacobsons Organ and is found on the roof of their mouth. It has a direct line to the brain where the information on the pheromones is translated: Valuable information to Bowser: Such as whether Fifi is ready to breed. Information on health and mood can also be transmitted. Yours, as well as another dog’s.
Pee, poop, and even feet carry pheromones which are created by scent glands. Because pheromones are volatile, they are released to the air and can travel long distances. That’s why Bowser might get excited if Fifi is in heat, even if she lives three miles away. Given an opportunity, he will go roaming and show up on her doorstep. I found the information about feet interesting as well. You’ve likely seen a dog kicking backwards after it has done its business. I’d always thought it was making a half hearted attempt to cover its poop. Actually it’s using the scent glands on its feet to mark its territory. It’s kind of a “I pooped here,” message. The pheromone is the sentence; the poop the exclamation point.
Scent glands near the anus provide all kinds of information, which is why dogs are always sniffing each other’s butts. Each dog has its own unique pheromones that travel to the sniffing dog’s Jacobsons Organ and then their brain where they are stored and interpreted for immediate and future use. A dog can actually recognize a dog it has sniffed years before. And remember its mood. “When I was a puppy, you were grouchy and bit me. Now you are old and I’m twice as big. Guess what?”




























In my next post on UT-OH, I relate how listening to the Lone Ranger on our family radio almost led to my head being smashed by a train. Our next focus post will be on Hoofing It with Ungulates.
