  • Sensitivity to touch, often resulting in pain

Otitis Externa,  infection of the external ear canal and Otitis Media, infection of the middle ear, are usually caused by bacteria or yeast. Other possibilities include accumulation of wax, matted hair, debris or a foreign object lodged in the ear canal. If your dog has an ear infection, he/she will be in considerable discomfort. 
Antibiotics are used for bacterial infections while antifungals are administered for yeast. Ear infections can also point to other problems such as allergies, hormonal abnormalities or hereditary diseases. 

Hematoma means the ear flap (pinna) is full of blood. This can be caused by vigorous head shaking, scratching or trauma to the ear area that damages the blood vessels. This is often set off by infection, mites, fleas or debris.

Ear Mites are common parasites that are highly contagious, often contracted from pet to pet. Excessive itching is the most common sign. Look for dark, crumbly debris that look like coffee grinds.

Deafness is difficult to diagnose. Usually brought on by age. Can also be caused by trauma, loud noise or infection, can also be hereditary or congenital.
