anti-dog potion

We moved around the perimeter while I hexed the other two cameras into useless junk, but just as I'd taken down camera number three, Susan gripped my arm and pointed. The foot patrol was moving by on their sweep.
The dog will get our scent," Susan said.
Martin drew a short pistol from beneath his jacket, and screwed a silencer to its end.
"No," I half growled. I fished in the pocket of my duster and found the second potion I'd made while preparing for the trip. It was in a delicate, round globe of glass about as thick as a piece of paper. I flipped the globe toward the path of the oncoming dog and heard it break with a little crackle.
The two patrolmen and the dog went by the area where I'd left my surprise, and the dog snuffled the new scent with thorough interest. At a jerk of the lead, the dog hurried to catch up to the guards, and all three of them went by without so much as glancing at us.
"Dog'll have his senses of smell and hearing back in the morning," I murmured. "These guys are just doing a job. We aren't going to kill them for that."
