Why are my dogs still itching a week after flea treatment, no fleas?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Female | 2 years and 8 months old | 52 lbs

My dogs had fleas, we treated them with a flea bath as well as some topical treatments. We also cleaned the house and bedding and put down flea dust. Both dogs are still very itchy week later. I have no physically seen any more fleas however I do not know why they are still itching.

I would recommend bringing Aries to the veterinarian to get medication to help with the itch. For the fleas I would either get Bravecto, SImparica or Nexguard. You can even use a Seresto collar. These flea preventions work great. You need to treat every animal in your home for at least 3 months. You can also get Capstar. Capstar only lasts for 24 hours so you have to do this in addition to flea prevention. This pill kills adult fleas only. For baths (if you wanted to give them) you can use dawn. I would leave dawn on for 10-15 minutes prior to rinsing it off. If by cleaning and vacuuming multiple times a week and all of this does not help you may need an exterminator.
