It's important to check your dog's ears regularly, ideally at least once a week. This helps to catch any signs of infection, wax buildup, or foreign objects early. During your check, look for any redness, swelling, or unusual odors, and ensure that the ears are clean and dry. If your dog has floppy ears, they may require more frequent checks due to reduced airflow. Additionally, some breeds are more prone to ear issues than others, so adjust the frequency based on your dog's specific needs. If you notice any concerning symptoms, consult your veterinarian for further advice.
