Dog dander is the dry, flaky skin that falls from your dog. If you have an allergy to dog dander, reducing it in your environment is essential. While there is no way to prevent dog dander, there are steps you can take to reduce the dander on both your dog and in your home.

Step 1

Begin by looking at your dog’s diet. Excessive dry skin or itching will increase the amount of dander. The itching is often a symptom of an underlying issue or allergy. Consult your veterinarian to rule out any possible allergies and treat as needed. Discuss the food you are feeding your dog and if it has enough essential fatty acids such as omega-3 and omega-6. These fatty acids contribute to healthy skin and coats. Make sure your dog always has access to fresh water.

Step 2

Brush your dog outside daily. Regular brushing will help remove dead skin and hair from your dog. Doing this outside keeps the dander from becoming airborne in your home. Talk with your veterinarian about how often you can wash your dog. Bathe him with a shampoo designed to reduce dander as often as your veterinarian advises. Harvard Health Publications recommends wiping your dog down in between bath times with fragrance-free, hypoallergenic baby wipes to remove dander on the hair.

Step 3

Address the dander in your home. Regular vacuuming with a HEPA filter vacuum helps remove dander particles from your carpet and furniture. Wash throw rugs, dog bedding and any other surface he frequents on a weekly basis. Mop hard surface floors weekly as well as wipe down all surfaces. Replace your furnace filter regularly. Consider running a HEPA air purifier on a regular basis to remove airborne dander.


  • Do not add fatty acid supplements or adjust your dog's diet without first talking with your veterinarian.


  • Discuss dander issues with your veterinarian and rule out any possible underlying medical conditions that may be contributing to increased dander.
