I've heard the tomato juice thing doesn't really work. The hydrogen peroxide/dish detergent seems to work, but I don't know the exact recipe. When Quiet Man got sprayed last year, we just had to live with it overnight until we could get him to the groomer's the next morning, because we have no place to bathe him and it was too cold to do it outside. The groomer's did miracles on him, he came out smelling wonderful, but our house on the otherhand was totally skunked! He rubbed all over everything! His collar had to be thrown away, along w/ some pillows. EVERYTHING had to be washed...beds, sheets, stuffies, etc. And we had to clean our carpets, sofa, etc. The windows had to be kept open w/ fans running and air freshener for at least 2 weeks. Even when I went away when I opened my suitcase I could smell the skunk! It was such an awful experience, and we don't let him outside alone after dark anymore!
I'm sure someone on here can give you the recipe....good luck! Did he get skunked, or are you just being proactive?
