My dog has flea bites. How do I treat them and prevent future fleas?

Updated On September 23rd, 2025

Hi! I have a 2 year Cavalier. I found some red spots on her hind legs and near her bug. They look like flea bites. She's currently not on any medication for them. What medicine would you recommend for her bites and for future use? She's 27 pounds.

You can use an oral preventive such as Bravecto, or a topical such as Frontline Plus or Advantage II. You can discuss options with your veterinarian. Whichever you decide on, use it for at least 3 consecutive months to break the flea life cycle. Year round use is recommended. Additionally, you will need to treat the environment. This includes vacuuming everywhere. Dispose of the bag or empty the canister outdoors immediately afterwards. Wash all bedding in the hottest water allowable by fabric and dry in the dryer. Use an area treatment, such as Indorex or Knockout ES, to prevent reinfestation.
