My dog has fleas and allergies despite meds. How to stop itching?

Updated On September 23rd, 2025

Pet's info: Dog | Border Collie | Female | spayed | 5 years and 11 months old | 32 lbs

The yard to my apartment complex is covered in fleas. I can’t treat the yard and management refuses to. My dog is on a vet recommended topical drug but she has fleas regardless. She’s allergic and breaks out in hives and scratches relentlessly. How do I help her find relief?

Thanks for using Petco Pet Education Center, formerly Petcoach! I recommend that you try a product called Capstar which can help kill a lot of fleas at once. You can consider switching to another flea preventative product such as Bravecto or Frontline. In the meantime, your veterinarian can consider a medication such as prednisone or Apoquel to help with the itch for now. Good luck!
