For at-home ear cleaning, all you’ll need is a dog ear cleaning solution and a clean cloth or cotton pad. PetLab Co.’s Clear Ears Therapy is a gentle, science-backed ear wash that is suitable for dogs and puppies who are 12 weeks and older. Never use cotton swabs to clean your dog’s ears. These can push wax and dirt further into your dog’s ear canal or cause damage if you’re not careful. If your dog’s ears are red and irritated or your dog is showing signs of ear discomfort, talk to your veterinarian before using an over-the-counter dog ear cleaner.
