Dogs that are afflicted with ear mites will typically scratch at the ears excessively and shake their heads, even pulling out their own hair as they scratch. Some dogs will shake their heads so much that an hematoma of the ear will form (with blood pooling in the ear due to breakage of a blood vessel). Also a concern is when dogs will scratch at their ears to the point that damage is done to the ear canals or ear drums.
