Do you dare to come closer, when you're already crawling at my feet with the hope for some treats? I have a surprise for you, my little puppy! You will now sniff my sweaty workout shoes intensively! Afterwards you'll move over to my stinky, sweaty socks and - last but not least - you will have to sniff or maybe lick my trained feet! You will keep that scent in mind to learn to detect your mistress from a one-mile-distance like a really good tracker!!!
