You only need to clean your dog's ears once or twice a month. In fact, if your dog has healthy ears it's often best to forgo cleaning entirely. Overcleaning can remove the waxy protective barrier of the ear canal.
However, if your dog is prone to ear infections or has recurrent problems, then you might need to clean once or twice a week. Check with your veterinarian.
Here's the easiest method.
Supplies: Cotton balls and a gentle ear cleanser recommended by your vet.
1. Soak 2 cotton balls with the ear cleanser.
2. Gently fold your dog's ear flap back to expose the ear canal.
3. Place the soaked cotton ball into the visible part of the ear canal.
4. Repeat with the other ear.
5. Replace the ear flaps and gently massage the ears for one minute.
Now allow your dog to shake his head to expel the cotton balls. Wipe the insides of the ear flaps and you're done. Remember to praise your dog and give lots of treats during the process.
Finally, never use a cotton swab in your dog's ears – you can damage his ear drum if he moves suddenly. And if your dog resists having his or her ears cleaned, don't force it. It's perfectly fine to take him to the groomer or veterinarian to have them cleaned.
