How To Clean Your Dog's Ears
Avoid Hydrogen Peroxide

Hydrogen peroxide is an antiseptic that cleanses and disinfects. It has a wide variety of uses, and some individuals believe it's a good product to mix with water and use on their dog's ears. This is false. While it does have many good properties and uses, it can damage your dog's ears, as they are quite sensitive. Hydrogen peroxide isn't gentle enough to use in such an important, delicate area. It can irritate the ears and lead to serious damage. It's especially dangerous to use if the dog has minor wounds or an infection in their ears. It can exacerbate the problem and be painful. Having their ears cleaned is already a stressful event for pups, and if they associate it with something painful, it will make cleaning more difficult in the future. Stick with veterinarian-approved products and avoid hydrogen peroxide.
