I thought they were good and killed fleas for 8 months, they are scratching and itching constantly and have fleas.
The Seresto Dog Flea and Tick Collar will not repel fleas but kills fleas when they get on the dog. Are you treating areas the dogs rest inside the home or visit in the lawn for fleas? If not, this is an important step for flea control as without treating those areas, fleas will continue to thrive and bother your pet.
Please take a moment to read over our flea guide to learn more.
