You will not get the smell out 100% for months. But then again, your dog is a short haired dog. When Zoee got it it took forever. Although, we did not realize it was in her ear for a week. YUCK! But she has two thick coats so for about 6 months after, she smelled any time she got wet. I bathed her tons of times. Several using the recipe Phred posted above and several times with other things I heard worked.
Poor thing was not allowed to sleep on the bed with us that whole time.

Also, Chippers may not be as bad since he wasn't directly sprayed. Good luck, and you will actually get used to the smell.......a little.
