I have never faced this type of situation. But sometimes It happened i heard about it. Oh yeah, the smell of a skunk is so much nasty and unbearable that it's simply not possible to be with it and especially when it comes from your pet, nature has come up with such protection for skunks :) Your method with hydrogen peroxide, I think, will be the optimal solution and we will manage to remove this smell.
I will remember your tips. Thanks for writing here. i Enjoyed it very useful post. You did well content. Hopefully your dog will be fine.
