Yes, seeing fleas despite using a Bayer Seresto Flea and Tick Collar for Dogs Large Gray can occur for several reasons. The Seresto collar may not be fitted properly, reducing its effectiveness, or your pet might have an unusually high flea exposure that the collar alone cannot fully manage. Additionally, it may take some time for the collar to eliminate all fleas, especially if your home or yard is infested, necessitating additional environmental treatments.
