Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

    Very greasy

    By Debbie59 on Nov 23, 2019

    I put it on my dog as normal, and the next day his application site had spread and it was a greasy mess, I hoped it would dry and go away but it's been over a week now and it's still that way. Now I have to take him in to get re-groomed. As for fleas , I treat my dog to keep them off. So he has none. So don't know at this point if it works.
