A good homemade ear wash solution for dogs requires 2 ounces of white vinegar, 1/2 teaspoon of boric acid, a few drops of povidone-iodine and a few drops of rubbing alcohol. The povidone-iodine can be removed from the solution if its smell is undesirable. After shaking the mixture, a dog owner should apply the solution by soaking a cotton ball, wiping the inner part of the dog's ear and cleaning with a wet washcloth.
Another homemade solution for cleaning a dog's ears involves mixing 1/3 cup of apple cider vinegar and 2/3 cup of lukewarm water, and then using a soft cloth or cotton ball to clean the visible area of the dog's inner ear. If the dog's ears are not excessively dirty, a pet owner may get rid of wax accumulation by putting a few drops of olive, mineral or almond oil on the visible region of the ear. Once the wax becomes loose, the dog should be allowed to shake its head, allowing the oil to spread.
To clean a dog's ears, a pet owner can also combine a bit of alcohol, 1/2 hydrogen peroxide and 1/2 white vinegar in a properly cleaned bottle with a nozzle. It is essential to consult a veterinarian if a dog avoids being touched on the ear or if a strange smell, redness or swelling occurs.
