I voted not to shave.

Where did he get sprayed? What part of his body? Could there be areas you have not cleaned that have skunkness in them? Like we had with Zoee's ear.
I'm baffled that none of the things you've bathed him with have worked. Zoee has a double coat and I was able to minimize the smell to make her bearable to be around at least. Either that or I just got used to the smell. You are probably super sensitive right now with smells, being pregnant, huh?
I just went back and looked at the other thread. When you bathe him are you letting it set on him for a while? I believe someone else suggested that as well.
Have you taken him to the groomers for them to try? We did that with Zoee too and they used Skunk Off. And they even told me it will not remove the odor completely. I wonder if a hair cut would help. Not shaved, just cut?
Gosh, I don't know!! I just would be heartbroken if I had to shave Zoee. Then again, I'm not living with Boone. And remember - it's hair, it will grow back.
I wish you the best of luck in finding a cure for the stinky dog.
