For the past 3 weeks he has been covered in fleas. I have to bath him in dawn every day but he still has fleas.
Even though the Seresto Dog Flea and Tick Collar continues to work for 8 months, it is not a complete repellent during that time. Fleas and ticks will still need to bite to consume the active ingredient, so it can take several hours for them to die. Be sure that you are still checking outdoors and treating as needed so that the dog is not bringing fleas and ticks indoors. You can also use an additional repellent on the animal if needed for long walks outdoors or in areas that you cannot treat. We have more tips in our Flea Treatment Guide as well. Seresto Dog Flea and Tick Collar will help ward off fleas and ticks, but it may not keep a flea from hitch hiking onto the pet in an area that may not have been treated. Be sure you are also treating the areas the pet frequents.
