I have a 5 year old female german shepard/lab mix. She might have a yeast infection in her ears. There's dark waxy buildup in her ear canals & she rubs& itches constantly. Is there an OTC med or any home remedies? Or should I take her in?

1/2 apple cider vinegar 1/2 rubbing alcohol. 70% not the 90% rubbing alcohol. The apple cider vinegar is an antibiotic and a light acid so it works on yeast and bacteria. The rubbing alcohol is drying so it takes care of the moisture that is letting the yeast or bacteria thrive. If your dog has any hair inside the ear you can clean it out every couple of weeks or at least once a month to prevent ear infection and yeast infections.

The doctor supplied a vinegar kind of mix for my pup but honestly I'd take her in incase it spread you don't want her to loose her hearing.

it's not ear mites either, btw. lol
