I'm still using this product on all three dogs and our cat after two years. It's still working, yes, it does smell quite strong of citronella for a day or two and it does leave oil on their coats where applied, but it is so worth it not having to use toxic chemicals! We have moved to a small farm and the dogs are running in the woods. Still no ticks or fleas!
I wanted to try this since it was all natural. The smell is very strong plus it leaves oil in your dogs fur. I tried it most of the summer and now I am fighting fleas. I have tried everything and can't get rid of them. Will not use again.
