I dont know it all but wont that mess there sence of smell up for a while?
Our dogs cant pass a skunk up. After they dispatch the skunk, they roll on it and play with it. After James goes in (cause im usually gagging and cant help him) and whips them all off of the skunk they will go find a hog. I don't know how the heck they can smell one after all of the skunk perfume they rolled in but they always do. They must have one heck of a nose is all i can say because all i can smell for the next few days is skunk!
So the answer to your question .... no it doesn't mess their sence of smell up. At least not our dogs.
