Skunked On Sunday




Mountain got skunked pretty good on Sunday, and Pearl caught the edge of it too, as she was right there at the hole.

Mountain came out OK, and was a bit dazed for a few minutes, walking around with her tail down, but she was back to her old self within a half hour. She had no burning of the eyes or blisters on her face (skunk spray is almost pure sulphuric acid), and was hunting again in short order.

The bad news, of course, is that the skunk stink lasts and lasts and last.

Skunk spray is a mixture of thioacetates and thiols (the stuff that stinks), mercaptans, and almost pure sulphuric acid. Bonded sulfur and hydrogen atoms in thiols attach to the same nose receptors that sniff out hydrogen sulfide ("swamp gas"). Human noses are highly sensitive to thiols and can detect the smell at just 10 parts per billion.

Skunk spray also contains compounds called thioacetates, which slowly break down into thiols. When a skunk sprays a terrier, thioacetates in the spray are absorbed into the skin of the terrier, and these thiocetates slowly break down into new thiols, resulting in the skunk odor reappearing on the dog a day or two or three after it has been well-washed in "Skunk Off".

Water seems to speed the process of thioacetates breaking down into thiols -- one reason that dogs smell skunky after they get wet. Getting a dog wet repeatedly over several days will not "drain off" all the thioacetates, however -- some part of the release is purely time-sensitive.

No matter what you do, it will take about a month or even 6 weeks before skunk odor completely disappears off a well-dosed dog. The best you can do is to invest in a lot of "Skunk Off" or make up your own using a box of baking soda, a quart of hydrogen peroxide (dilute 3%), and a squirt of hand soap.
