I have been using frontline for about 6 years- we live in a heavily wooded area and I have to say this stuff absolutely works.

We’ve been using frontline flea and tick prevention for years on our dogs. It’s always done the job especially living in New York where ticks are sprouting up like wild fire. Comes in plastic applicators containing the liquid preventative. Super easy application, we apply each month per instructions. Never had an issue with any skin irrigation on our dogs. A little on the pricey side, but gives us the peace of mind of tick coverage for our dogs so that’s priceless.

The best flea repellant on my dog! I've been using it for many years. It's the only product that gets rid of eggs, and adult fleas.
