I checked the Novartis site to read about Sentinal Flavor Tabs and there's nothing there that indicates it also takes care of ticks. Because we live in an area where there are plenty of ticks, we use K9 Advantix which takes care of fleas, ticks and mosquitoes and Interceptor which we use to prevent heartworm; it also removes/controls roundworm, whipworm, and hookworm infection. It would be great to use only one product, but I'd be concerned about the tick situation.
I think I may call a local vet to where we live now and see if I can pick some revolution up.
