For the 8 years we have been keeping goat we have only come across an ear problem once. The ear was clogged and there was brown gunk oozing out not forgetting that yucky smell that emitted from it. There was an infection in it obviously as the Goat scream bloody murder when its ear was inspected.
After cleaning the ear out with most of the gunk, using a cotton bud and some anticeptic cream we applied a few drops of a combination of equal parts of Extra Virgin Olive Oil, crushed Garlic (garlic is a natural antibiotic), a capsule of Vitamin E.
On the second day we checked the ear and repeated the same drop recipe after giving it a good clean with cotton buds. The ear seemed to be doing pretty well after the third treatment and we followed up with weekly drops of equal parts white vinegar and rubbing alcohol
From then on we used the same combination of equal parts of Extra Virgin Olive Oil, crushed Garlic and Vitamin E to treat for ear mites and infections of bacterial or fungal origin.
