An ear infection is the most frequent issue that causes excessive head-shaking in dogs. These infections can occur in the outer, middle, or inner ear canal.
This health problem is uncommon in adult dogs and is more often seen in puppies, especially if they come from crowded living conditions.
Dogs can have allergic reactions to something in their food or environment. This can cause itchy skin in their ears, which may be the reason why your dog is shaking its head so often.
