Have been used from April to October and haven't found any bitten spots on my dog! Strongly recommend :)

Very pleased. It was recommended by a fellow dog rescuer. All itching and signs of fleas disappeared within a day!

I have been using Seresto for over a year. I would recommend to family and friends.

We love this product as it is fast acting and since we live in Florida, our two dogs are exposed to all types of little critters. Although the product states it last for 7-8 months, we get them every six months as by then the protection is staring to fade and we don’t want to take chances.

Works 8+ months. My dogs have never had a flea because of this collar and it works. No odor and adjustable lengths.
