Hi Dog Obsessed. Go on line and go to Sentinelpet.com When you’re there check on Sentinel Spectrum. On the left hand side of the page you’ll see a list of all the things it deals with. Click on each item one at a time and read up on them. The first one will be Heartworms, of course. Second one on the list is fleas and then so on and so on about the different worms. Let me know if you need more information.
