I have two dogs and three cats and always had a problem with fleas, especially during the summer months. These flea and tick collars are amazing. Doesn't seem to matter where they wonder, all of my pets have been flea-less since using. And it does last for at least 8 months. Best flea prevention I have ever purchased.
Best product out there. Never really cared for collars but after trying the popular drops with no success, I was recommended to try this product. After a couple of days the dogs quit scratching. Amazing product
Our three dogs went to the vet for vaccinations and came home with fleas. Frontline Plus proved to be inadequate for the job, but the Seresto collars, along with spraying have taken care of it.... I think.
