loads of wax is a good indication of mites... hope it sorts it out ..if he continues scratching or shaking his head he may need a stronger drop such as canaural which is only available on prescription..sometimes mite cause the ear to become inflamed he may need the vet to take a closer look as it can be painful for your pet.
I only buy epiotic or similar to clean the ear any redness or such I visit the vet.
