  • Less stress. With up to 8 months protection against fleas and 4 months control of ticks, you don’t have to worry about monthly treatments for fleas and ticks any more.

^The Seresto® dog collar controls fleas for up to 8 months and ticks (paralysis ticks, brown dog tick and bush tick) for 4 months. Some limitations apply – please see Product Label for full details.1,2 Brown dog tick control is not affected by bathing, swimming or shampooing.1,2 Always use a soap-free shampoo. The effect of shampooing or exposure to water on the efficacy of the collar against paralysis tick and bush tick has not been established. Shampooing or frequent exposure to water (e.g. swimming, bathing) can accelerate the depletion of imidacloprid and may reduce the period of efficacy against fleas.1,2 References: 1.
