"This flea control will work for 3-4 weeks and is not water resistant/proof. Is your dog very active? Does your dog like water? Will your dog be groomed before the next application? If so, you may want to consider something else. This stuff will definitely do the job and is cheaper than Advantage or Frontline. But remember, you usually get what you pay for. Personally, I had to switch because my dog loves water."
