I take several dogs hiking every day and one of my favorite spots to park & hike has been soiled by a deer carcass. A deer (hit by a car?) died and it's carcass laid in a roadside, gravel trailhead for a few days. The state picked up the carcass finally but of course there is a spot with blood, ick and the smell of death. I'm in a very dry area so there's not much rain and the female dogs want to rub themselves in the mess. Using a leash is very painful with three dog especially since this group has been hiking off leash for years.

Is there something I can put on the spot to keep the dogs away? Vinegar? Hydrogen peroxide? There must be something worth trying. The spot is gravel & dirt with a noticeable amount of dried blood and who-knows-what.
