No, please do not instill anything into your dog's ears without your veterinarian's advice. Your dog also needs an ear exam to determine whether the ear drums are intact before any medicine is instilled into the ear/ If the ear drums are not intact, any medication getting into the inner ear can cause serious inner ear problems such as balance issues, etc. Please visit a veterinarian with your dog and bring the results of the sensitivity report with you. Your vet will then be able to examine your dog's ears and decide which route of medication is suitable. Never instill H2O2 into a dog's ears.

    No, not at all! This is terrible. Would you put apple cider vinegar and hydrogen peroxide in your ear? You also don't know if the ear drum is intact, and this can cause serious problems if it's not. Good on you for asking a professional before trying it. Take Peques into the vet in the morning to have his ear infection treated properly. I hope this helps!
