My dog has fleas again after treatment. Is it safe to re-treat?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 18 lbs

Hi My 7 kilo, 13yr old Jack Russell X was given advocate 3 weeks ago but in the last week he is riddled with live fleas again. Have treated all house too. Should I use Advocate again at 28 days or Advantage 11. He had a terrible reaction to Bravecto last yr so nervous of ingestied and spot ons since. He swam a lot over last 3 weeks so may have weakened it? Used Indorex and hoover/boil wash everything - but still keep finding live ones in his fur. Am at wits end as can’t re-treat him yet?

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
