Also, watch out, some PBGVs are allergic to some of the ointments used in treating ear infections. Recurring or stubborn yeast infections may be related to allergies. So if you have been through a treatment with little or no results, an allergy regimen is recommended. The irritation in the ear canal sets up a perfect place for yeast to grow. Once yeast is cleared up, it should be followed up with a cortisone drop, HB101 or Burocort.
Mites can reside very deep in the ear canals.
The coat should be harsh and rather thick, the texture similar to that of a goat. To prevent matting of the coat, dogs should brushed, followed by combing, once weekly. Small mats will be easily removed in the process of combing. Only neglected coats will mat severely. For help with mats, you might try something called The Stuff.
