are caused the vast majority of the time by the ear retaining environmental moisture favorable for bacterial and yeast growth. My prior Lab readily got swimmer's ear. My current two have experienced no such problems. All 3 have commonly been given 2 trips a week to the pond for swimming. All 3 have been fed Propet Performance dry dog food formula, and all 3 have never refused eating it under normal health conditions. Neither has it caused allergies, or other symptoms of poor health. In fact all 3 have thrived on it. Note I have no economic interests in Pet Carnation Inc who makes the food.

Except for extremely rare cases diet is not a cause for ear infections. Also once the ear has been infected severely, it will become so again. The 1:3 parts of white vinegar to distilled water or even alcohol seems to be a good preventative.
