Consider yourself real lucky! You don't want to have a run-in with a full grown skunk, and especially if he's already tangled with a couple dogs. Here's a true story that'll usually bring a laugh or two .... enjoy!
Many years ago I raised some pretty good bird dogs ... Brittanies and Springers usually. Well there was a time when I had one of each in training, they were only 14 days apart in age and both were hard core 5 year old studs. I had to watch them pretty carefully when they were out together. Most times they would hunt like fools for me, each one a good backer for the other, but every now and then they'd lock up and fight till I could get in between them. Well, one summer afternoon, they jumped a skunk crossing my fairly large, fenced back yard, but instead of fighting each other, they took turns fighting that damned skunk while I swear the skunk would sit and rest in between dogs. Then they'd change dogs and go at it some more.
Well, my neighbor from across the fence would often want to come over when I would be working the dogs and 'help' me, and when he heard all that commotion that day he took a look over the fence and simply said "Hell no, I ain't gettin' into that mess"! Well, thanks friend.... says I. So, when I really need you it ain't happening.
I finally got both dogs off the damned skunk and back into their respective kennels .... all the time pulling on them and gagging worse than a new baby eating his first 'Smashed Peas' out of a jar. My buddy from next door ran to his place and right back out with some V8 juice .... about a Qt can if I remember correctly. Said he had heard it was better than tomato juice for de-skunking dogs, kids, dog handlers, etc.
Well, the wife wouldn't even let me on the porch, much less inside the house. Told me she didn't have any damned tomato juice and even if she did she'd have to throw it at me out in the yard. She actually said I stunk .... but I'm pretty sure she knew it was the skunk.
So there I am with one dog by the collar pouring that V8 juice all over him and him trying to lick it off as fast as I'm pouring it on, when all of a sudden that skunk jumped up and went to hissing and jumping around like he's been struck by lightning. I swear that skunk was challenging my Springer to another round instead of heading to the gap under the fence and then on to high country. The dog is raising more hell than any dog should be allowed, and me still gagging like a maggot, but by now I'm really heaving and stuff comin' up out of my gut that just caused more gagging.
Finally got both dogs cleaned up the best I could using the neighbor's V8 along with some kind of dish soap, and a touch of kerosene on a soaked rag IIRC. But, when I finally headed for the house, the wife was out on the porch telling me exactly why I was not coming up on that porch till I bathed down just like I had done those dogs. I did that, but finally had to commit to coming in the house butt naked and leave the cloths outside to air. And just to show my neighbor my appreciation, I hung those clothes on the fence directly between my house and his. Most of the smell wasn't too bad now since by now my nostrils were so burned out by the skunk smell I could barely smell anything. And when I did actually smell something, good or bad, the gagging would start all over again.
It was several days before those cloths were dried and aired out enough I could actually walk up to them, but even then I didn't want to touch them and decided the best thing to do would be to just through 'em in the garbage hole and burn 'em. I'm pretty sure if I had even thought of putting 'em in her washing machine/dryer, I'd been in real trouble.
And after all that I went through, I never once heard her tell those dogs that they stunk. That kind of hurt my feelings. And all during the next bird season, if one of those dogs got within a country mile of a skunk, he'd circle completely around the spot where he'd smelled the skunk and come all the way back to my heel until I told him to 'hunt that bird'. jj
he said there was no problem as like you mentioned the flame won’t get sucked into the pipe. I will say as I got more comfortable doing my own work I used the soapy water test.
