Head Shaking in Cats and Dogs

Head Shaking in Cats and Dogs

Common Causes

Causes are listed in order from most common to least common. In dogs and cats, ear problems are by far the most common cause of head shaking.

  • Ear infections are the most common cause of head shaking in both species. Infected ears frequently are painful, produce pus or excessive wax, and may emit a foul odor.
  • Allergic reactions to fleas, pollen, or food can cause itching in the ears, leading to head shaking.
  • Foreign objects lodged in the ear will cause head shaking. Plugs of wax and pieces of plant matter, such as foxtails, are the most common foreign bodies in ears. Foreign objects frequently are located deep in the ear, requiring special instrumentation to locate them.
  • Ear mites can cause marked head shaking.
  • Trauma to the outer portion of the ear can cause irritation and head shaking.
  • Polyps, growths, and tumors in the ear are rare causes of head shaking.

Recommended Course of Action

Most problems that cause head shaking are unlikely to improve without intervention. Carefully inspect both ears. If no obvious source of the problem can be found and corrected, schedule a veterinary examination.
