It's odd here... when I adopted Chip at 4 , they told me he always had ear problems... and came with all the washes etc. He never was in water , so it wasn't that ... no ear mites nor wax. In the 5 years I've had him, he's never had an issue ! Could it have been stress ?? Food ?? I've been stymied by this . Hey, I'm thrilled... but why did they have problems and I don't ??
