Can't help you here....I don't give baths to my ferrets. (unless they get into some really dirty or sticky).
Ferrets are clean animals and they can take care of them self. They really don't needs baths.
If your ferret has a odor...then you need to look at your ferret's environment.
Such as:
What type of food are your feeding
How often you clean the cage and litter box
How often you switch out the bedding (hammocks, sleep sacks, etc.)
Years ago, I purchased the dry shampoo for my horses. It was a waste of money.....I give the dry shampoo's thumbs down.
