I could have used this several times (a) a few years back, I couldn't stop a skunk from using our back porch as natures path, every friggin night. So I shot him, right outside my office which is another room connected to our bedroom with a backdoor to the back porch. I shot him in the head as recommended but that didnt stop the ungodly 30 foot spray he unleashed in my yard for a good solid 2 minutes. (b) the dog loves skunks, her last spraying was a couple of months ago.
