Hey man, I feel for ya. Ive had a number of dogs and my self speayed more that I like to think about. I'm a zookeeper, and when I took care of skunke in a zoo 10 years ago I used a product called either Skunk Off or Sjunk Away, and it flat works. Took the smell right off my skin, clothes,and my dogs. I can't remember where we got it from but i'm sure a quick web serch might find it. Good luck.
