I used Sentinal for many years, alone, with excellent results. But, I treat my yard also, so I have never had a flea issue....never seen a tick around here....I worry about all the toxic drugs we have to give our babies to prevent heartworms, then fleas, then ticks, worms, then there are the vaccines.....I think I would feel more comfortable using Revolution, which is one drug that kills fleas, ticks, ear mites, and heartworms, without having to combine multiple other drugs. Personally, I alternate Revolution and Canimax,,,,this gives me a very broad spectrum of parasite preventative, they are given individually, not doubled up, and they are rotated in order to prevent the dogs from getting an "immunity" or tolerance to either drug. This has worked super for me and my group, I have never had an issue with any of the fleas, ticks, earmites, or worms, including tape worms....and I always put the Revolution around a 1.5 inch area on the shoulder blade area, so it does not go on the same exact spot every time....that helps me think it wont be irritating the same exact spot every month, which may not even be an issue.....just is more acceptable to me. |
