My dog has flea drops, but I found a live flea. Is this normal?

Updated On September 23rd, 2025

Hey again so I applied the drops to my pet a week ago but my dog picked up a live flea outside. Is this normal? I vacuumed the whole carpet and went over him with a flea comb multiple times and found nothing.Is it normal to see a single flea from time to time as in the two years of having him this is the first time. Should I expect an infestation or more to come in from outside? Or will the fleas die after biting and I do not have to worry? Sorry my OCD is going crazy bc I have never seen a flea

It might be a flea that jumped on him after the application, this can happen but if you find more than one and they are alive then the product you are using is likely not working and you need to change it to something else such as Bravecto, Advantage or Revolution.
