A skunk needs to be able to raise its tail to spray - it shouldn't be able to raise its tail in a live trap... If it isn't in a trap, DH kills with a head shot and then buries it right away. A skunk can spray more than once, I saw one spray my sisters dog twice. The second spray was definitely not as strong of a spray, but it did spray. Funny how when it isn't your dog it is cool to see the yellow mist spray the white dog.
My husky got sprayed one time, it soaked her right down to the skin. She had taken off and didn't come home for 2 days. I scrubbed her down 3 times and she still smelled skunky every time her fluffy under-coat got wet, until she shed it out 3 months later.
