I asked this question recently and was surprised how some dog owners deal with the problem.
For example: you are talking about the dog's Fur Coat getting sprayed... which wouldn't be such a problem if the dog was wearing a Rain Coat.
Clearly your dog has no problem with the smell of a skunk if it continually gets sprayed. You won't change the dog and I guess you won't be able to change its coat either, unless you remove the cause of the problem. Many dogs enjoy rolling in rotten or putrid smells. If your dog is doing this then there is a chance that another dog is threatening it or bullying it in some way. You will need to stand at a distance and observe what it does.
Of course skunks only spray dogs etc. when they are attacked or feel threatened... it is a defensive reaction. Perhaps you have taught the dog to do this and in reality the only answer is to Change that Behaviour. Good Luck.
