My dog's on Advantage, vet found no fleas. Could there be flea eggs?

Updated On September 23rd, 2025

My dog has been on Advantage for two years. I asked my vet if my dog had fleas and the vet found no evidence after a thorough investigation and flea comb through. Is there any indication that there could be fleas or flea eggs if my vet said no?

You can also check for little black specks on his fir closest to his skin called flea dirt. Likely though if you apply flea prevention and the doctor found no evidence he should be ok but if you find these little black specks of dirt, a way to conform if it is indeed flea dirt is take a paper towel, wet it, and smear the dirt specks around. Normal dirt will not look any different after doing this however flea dirt will have a reddish color to it
