Last Summer had the worst problem with fleas we had ever had. Frontline Plus did nothing. Bought these collars and within 2 days all fleas were gone off of all 3 dogs and 4 cats. Will never use anything else. And it lasted for months!

Great!

I have used the Seresto collar for my small dog and it worked beautifully. We live in a very wooded area full of flea and ticks. I actually found a tick that she picked up during a walk but it was dead before he could bite her. It lasts longer then 8 months, for us it worked for 10 months. You can't beat the price for even 8 months of protection. Our girl is allergic to fleas and costs big money in vet bills and shots but this collar is 100% effective for us.

I have been using this product for the past 16 months and they actually work. I buy the large for my boston terrier and my dobie and the small for my Pekingese. Highly recommend this product
