Is your dog showing signs of Otitis... an inflammation or infection of the ear?
Normally, your dog’s ear should not be painful to touch, and clean and dry with no signs of discharge. Some dogs may produce a little bit of excessive wax, which would be a brown, oily substance in the outer canal and ear flap. An infected ear will usually produce an abnormal ear discharge, which may or may not be observably present on the outer ear. The discharge can appear in a range of colors from dark brown to green to white. The color of this discharge can be very helpful in determining the cause of the otitis.
