From Dorland's Illustrated Medical Dictionary, 27th Edition: Otitis: "inflammation of the ear, which may be marked by pain, fever, abnormalities of hearing, hearing loss, tinnitus (ringing in the ears) and vertigo." Vertigo: "an illusion of movement; a sensation as if the external world were revolving around the patient, or as if he himself were revolving in space. . . Vertigo may result from diseases of the inner ear . . ." Ataxic (a.k.a. atactic): "lacking coordination" My vet also said that Frontline was good for ear mites, as well as a bunch of other insects. Ear mites are almost as difficult to get rid of as fleas are!! Good luck. Tony [Posted in FML issue 2570]
