I couldn't tell you just by looking at the ear externally, a sample needs to be taken from the ear and the vet needs to look at this sample under the microscope, only this way the vet can know for sure if it is an ear mite infestation, yeast infection or bacterial infection and then treat the infection accordingly.

    The short answer to your question is that ear infections are most commonly caused by underlying allergies. Both yeast (Malassezia) and bacteria normally live on the skin and in the ear canals, but can cause infections in some cases. The following handout has an excellent description of ear infections in the first section. I hope it will give you a better idea about ear infections in dogs. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=632 I hope that was helpful! Thanks for using PetCoach.

    It's probably an ear infection, often it cannot be seen from the outside. Ear infections are very common in dogs, it is usually caused by either yeast or bacterial disease. the treatment is usually simple and straightforward, you will have to take Peppa to the vet and get the ears checked, then a prescription ear drops will be prescribed according to the infectious agent.

    An ear infection in a dog is usually either caused by bacteria or yeast in the ear that becomes overgrown and causes inflammation, debris and pain. It is usually in the outer ear but can cause damage to the eardrum and go into the middle and inner ear.
