    I guess this is why Jazz can track down a dead something from a looooooooooooonnnnnggg way off. And why she "reads" me all over when I've been out without her! That far away look in the eyes while she processes all that info. :rofl:

    So far science can't duplicate a dogs sense of smell.
    Some breeds are going to have a better sense of smell than others.


    Dogs' Dazzling Sense of Smell | NOVA | PBS

    https://www.pbs.org/wgbh/nova/nature/dogs-sense-of-smell.html
    Figure 2: In the rear of a dog's nose lies the olfactory region (yellowish-brown), with its scroll-like tissues bristling with smell receptors. Respiratory regions appear in pink. In us humans, the sense of smell is relegated to a small region on the roof of our nasal cavity, along the main airflow path.

    Figure 1: When a dog breathes in, the air separates into distinct paths, one (red) flowing into the olfactory area and the other (blue) passing through the pharynx (black) to the lungs.

    Put another way, dogs can detect some odors in parts per trillion. What does that mean in terms we might understand? Well, in her book Inside of a Dog, Alexandra Horowitz, a dog-cognition researcher at Barnard College, writes that while we might notice if our coffee has had a teaspoon of sugar added to it, a dog could detect a teaspoon of sugar in a million gallons of water, or two Olympic-sized pools worth. Another dog scientist likened their ability to catching a whiff of one rotten apple in two million barrels.

    Looking at this picture it makes you wonder how much damage the ‘gentle leader’ is doing to the snout?!

    I'm living with a Dutch Shepherd, (not mine, my housemates dog) and watching her go through nosework classes is stunning. She's obviously a natural, and being high drive makes her fast, and it's SO MUCH FUN, for all of us. She just got her NW1. Anyone considering your dobe (or any breed) for nosework should go for it - it's fun, if nothing else and so amazing to learn what they already know.

    I'm exposed to so many things on the job (including dogs and cats) so it's no wonder our two have to carefully sniff me when I get home. It's like they're saying "Now what have you been doing when you're away? :nono:" LOL
    I can't wait to run across a service monkey to see what they think of that scent. :D

    Are you serious about “service monkey”? Or was that a typo?
