Sorry to recommend things you already tried. I did not know you had tried Apoquel and are using flea control.
I have not seen Animax or Panalog cream for awhile, only the ointments.
To stop hotspots, you have to identify and treat the underlying condition, which is usually an allergic reaction that leads to a secondary bacterial and sometimes yeast skin infection. Most of the time hotspots are not caused by food allergy but by something in the environment.
You can see a dermatologist for allergy testing, or have your veterinarian do allergy testing to find out what she is reacting to. If those things can be avoided, the hot spots should stop. If they can't be avoided, then hyposensitization (injections) can be tried.
These supplements have helped other allergic dogs in my experience, but unfortunately all allergic dogs are different so no one will help all allergic dogs:
Fish oil, evening primrose oil. Probiotics to boost the immune system. Quercetin. Nettles. Antioxidants. Oatmeal shampoos.
Sometimes hotspots and skin problems reflect underlying internal disease, so blood tests to check for things like liver disease should be done if that has not already been done.
Allergies are so frustrating to treat, because there is no cure yet. Every case is different so what helps one dog does not work for the next one. If you have already tried all these things, seeing a specialist, a veterinary dermatologist would be my next step if Zoey were my own dog.
Let me know how she is doing.
