Yep!

Like the others have said=Aint no way tell when they are gonna spray only that they can! Have kilt more than my fair share and only had a couple that didnt :-[
Only exception I've seen is the Doberman I had for a farm dog many years ago. The first skunk that I know he got spayed him BAD, the dozen or so after that got drug in the yard deader than a door-nail and stunk the whole barnyard up but that dog didn't stink at all.....Still wondering how he pulled it off!
