The tastes and odors in that dog treat were really messing with Max's nose and tongue. He looked up at her wagging his tail, wondering if she would give him more.
"No more of those right now, Maxy," she said. "But we might need to see you put that nose of yours to work on something else... and maybe some other part of your body as well," she winked to the audience. The Madame snapped her fingers and effortlessly duplicated a fire hydrant from the middle of town on the other end of her stage. The original hydrant was still where it was, for everyone's safety, but this one was identical, in more ways than one. The audience burst out into a cacophony of guffaws.
Max suddenly caught whiff of a bunch of other dogs, and he whipped his head around to look at that corner of the stage. He knew exactly what dogs were known for doing on those, what Madame was trying to indicate to him and to her audience. That didn't stop him from snooping over to take stock of all those scents that were on it. Every dog that had peed on the original hydrant was detectable on this one. Max was impressed that he'd be able to identify his fellow canines so easily almost wherever they'd been from now on. Heh, "fellow canines." Just think of that! Other people's pets were his equals now. He felt his penis stiffen and then warm up as it was encased by his own skin and tucked away. His balls warmed up too, with the familiar coziness of fur growth. Looking back, he did a double take at what he saw: it was a furry, cream-colored dog sheath, hanging off his belly like a travel pack. He wasn't just going to be peeing on stuff to leave messages from his friends from now on, he was was going to be doing it through the same sort of release valve they used!
Max circled his hydrant enthusiastically, ready to leave his first mark and not bothered by the whole audience watching him. He lifted his leg high like he'd seen his neighbors' furry friends do countless times, and visibly calmed down a little. The audience laughed at the sight. Max enjoyed the personally identifiable smells in the warm trickle that was exiting his sheath. The name "Max" was suddenly a bit less important to him--it was a useful sequence of sounds for humans to use, of course, but it wasn't who he really was deep down inside the way this was. Max understood what he SMELLED like, now--what he'd smell like to any other dogs who might stumble upon his markings after he'd left the scene. He strutted away with his head held high, still relishing the scent of his mark in his nostrils.
