A dog will shake its head under normal conditions for a few reason, such as when the dog has just gotten out of the water or to shake seeds or burrs from its ear. Even a dog hair can irritate the dog enough to make it shake its head. When your dog shakes it head, it is important to check for any foreign objects, allergic reaction and bites in its mouth, throat and ears if you can.
Alongside the shaking, the dog may exhibit poor balance and may tilt its head and experience loss of co-ordination. The animal may also roll its eyes or upwards or side-to-side and while this is distressing for both the dog and its owner, the best way to help the dog is to calm it and reassure the animal.
