Why does my dog keep getting skin infections despite allergy meds?

Updated On September 23rd, 2025

Pet's info: Dog | Shih Tzu | Male | neutered | 20 lbs

Dog continues to get scabs that turn red when picked off. He also keeps having bacterial infections on his skin. He takes allergy meds everyday. No fleas. I take him to the vet and they will find bacteria and white blood cells. I bathe with sensitive soap...I also give him allergy sensitive food. why does he keep getting bacterial infections?

Poor Aspen. He is obviously very sensitive to some type of allergen which that be grass, dust, tree, chicken/beef, fleas (even if you aren't seeing any), and more. i would recommend to talk to your vet about apoquel or a course of steroids. Both of these are great for allergies. Apoquel is preferred as it is safer long term. Also I would recommend a prescription hypoallergenic diet for a minimum of 12 weeks to see if it helps his skin. When you do a food trial you cannot give him any treats or human food. You also need to make sure his hesrtworm prevention is hypoallergenic. I hope this helps! Allergies can be frustrating but it is important to figure out how to manage them as they cannot be cured.
