If it does not seem to be working then I suggest you get him a different product. I like the oral pills either Bravecto or Nexgard. You can get these products at one of VETCO's clinics inside Petco stores. Take Jackson with you to the clinic. There is no exam fee. It would only be the cost of the product. Here is a link to the clinics in your area.

You should also treat your house for fleas:
