Seresto provides up to 8 months flea protection and 4 months tick protection for dogs in a waterresistant^, odourless innovative collar format.
The active ingredients in Seresto are specially formulated for steady dose adjusted release that spreads over your dog, remaining in the fatty layer of the skin and coat, where they are effective against fleas and ticks.
