Thread: Dog ear infections

The brown, smelly, waxy gunk is either a fungal (yeast) infection or bacterial infection. Symptoms are similar, but the fix is different. Sometimes the bacterial infection originates from ear mite infestation. The only way to know for sure is to look at it under a microscope.

So you really need to find a vet who is prepared to do the right investigation and determine the cause conclusively.

The puss however, is a different matter and typically a sign of foreign body.
