My dog has fleas again in 9 days. Can I reapply topical treatment?

Dogs are not supposed to get wet for at least 24 hours after application of a topical flea medication, and more than likely it was washed off during the bath. You can reapply the flea treatment, and I would give them Capstar given you have seen fleas. It's a one time pill that starts killing fleas within 30 minutes, and it's safe to be given at the same time as the spot on treatment. Just as a note, I would not recommend using Frontline. In my experience (and from the experience of many colleagues), there is a resistance to Frontline, and you may not get the best results from it. I recommend using Advantage or Revolution instead. You will also have to disinfect the environment. Wash their bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home.

In severe outbreaks, 2 weeks between different drugs is ok. You will also need to use a household flea treatment in order to break the cycle, only 5% of the flea population are adults and actually present on pets, tge remaining 95% are eggs/large and will continue to hatch, develop and reinvest your pets. All in contact animals should be treated together and also given a tapeworm treatment because tapeworms are also transmitted by fleas

Hello, you can retreat him now and keep him off the water for atleast 5 days. You’ll need to continue to treat your house and deep clean for atleast a month. Other oral preventatives you can try are nexguard. Hope this helps and best of luck

It is safe to reapply the Frontline now, but in my experience, it doesn't have great flea protection. You may have better luck with Advantage products or a Seresto collar. The best flea protection is the prescription oral flea preventatives, like Bravecto or Nexgard.

Hi there. If Frontline is not working for your dog (which is sadly very common, in my experience), I would recommend using a different medication rather than reapplying a second dose. I normally recommend Nexgard, Bravecto, Simparica, or Credelio for fleas and ticks - all of these medications are safe and effective, and would be fine to give even if you applied Frontline 10 days ago.

A [flea](https://www.petcoach.co/article/fleas-life-cycle-anatomy-disease-transmission) infestation on your pet or in your home can be [difficult and frustrating](https://www.petcoach.co/article/why-are-fleas-so-hard-to-kill) to deal with. Yes, if after two weeks the [flea preventive you applied isn't working](https://www.petcoach.co/article/6-reasons-your-flea-prevention-isnt-working), you can reapply flea treatment early, or switch to another brand. I recommend using Advantix or a chewable prescription product from your vet, like Bravecto, Nexgard, Simparica, or Credelio. This recommendation is unrelated to Petco or PetCoach. If you are seeing fleas on Mia now, you can give her Capstar ([Nitenpyram](https://www.petcoach.co/pet-medication/nitenpyram)). It's a one time pill that starts killing adult fleas in 30 minutes and is safe to use with a topical treatment. Use a monthly preventive on all pets for at least 3 consecutive months to break the flea life cycle. Year round use is preferred. You will also have to [treat the environment](https://www.petcoach.co/article/5-tips-to-get-rid-of-fleas). Wash all bedding in hot soapy water, and vacuum the furniture and carpet surfaces. Discard of the bag or empty the canister outdoors immediately afterwards. Use a spray, such as Indoorex or Knockout ES, in the house and to prevent reinfestation.

Hi and thank you for your question on Petco Pet Education Center, formerly Petcoach! Generally speaking, it is advised to administer one type of topical flea/tick preventative at one time. Administering more than one topical type in a 30 day period may be an overload to her system. The Fipronil is liking absorbed already, so I would not advise you apply the Vectra. Instead, you may ask your veterinarian about a administering capstar or another fast acting oral flea treatment medication. Next month, you may apply the Vectra. Hopefully that will do the trick.
