I have been using Enjay products for at least 15 years on my often skunked dogs.  My next door neighbour has a habit of putting all her scraps out for wildlife in the area.  I can see the skunks tails waving on her back porch. One summer both dogs were skunked 6-7 times.   The Enjay shampoo removes the skunk smell completely.  My house still smells - but the dogs don't!!    All of my neighbours have borrowed the shampoo from me - and I originally had the 4 Litre size and am now down to almost nothing with summer upcoming !!  We have already been skunked once last week and I was panicking that I would run out completely.
