Ear tumors in dogs are abnormal growths that can develop in any part of the ear canal. However, in dogs, tumors of the ear canal are more common in the outer than in the middle ear or inner ear. Ear tumors in dogs can be benign tumors or malignant tumors. Generally speaking, benign tumors in the ears are more common than malignant ones. The most common clinical signs in pets with ear canal tumors include an inflamed, itchy, and painful ear, persistent smelly discharge (that can be waxy, pus-filled, or bloody), head shaking, and ear scratching.
