Dog's ears are prone to problems, so it is important to check them regularly. Here are some things to look for.
Redness or swelling inside or around the ear canal is a sign of infection.
A clear or cloudy discharge from the ear canal is also a sign of infection.
A bad odor coming from the ear canal is another sign of infection.
If your dog is scratching their ears excessively, it could be a sign of an itch or infection.
Head shaking can also be a sign of an ear problem.
If your dog is showing signs of pain in their ears, such as whining or yelping, it is important to see a veterinarian right away.
