The natural actives in Only Natural Pet flea & tick products are scientifically proven to kill or repel fleas, ticks & mosquitos. You can rest easy knowing your pet is protected all season long without the use of harmful chemicals.
I started my 3 dogs on their flea control program at the same time. One dog got the EasyDefense Flea & Tick Tag, while the other 2 dogs got a conventional brand. The ones on a conventional brand are still scratching. That's enough proof for me that this system works!
