Hi there and thanks for your question! If you are using a product that is OTC, it may be because the product is not working well. A lot of OTC products do not work as well as Rx products you get from your vet. I would advise you talk to your veterinarian about getting Toby on a Rx flea and tick medication. There are lots to choose from! Best of luck and I hope the fleas leave soon.
