Sporting Dogs: Their Points and Management in Health and Disease

by Frank Townend Barton

DEAFNESS

Deafness may be "complete" or only "partial," and confined to one, or affecting both ears.

In some dogs it is congenital, i.e., present from birth; in others acquired.

Severe canker will cause deafness, so will a blow over the ear.

Morbid growths in the passage, and accumulation of waxy material, etc., will likewise produce "partial" or "complete" loss of hearing.

Treatment must be directed to the removal—whenever possible—of the cause.

MORBID GROWTHS IN THE EAR-PASSAGE

Occasionally the middle ear is the seat of various morbid growths, either of a wart-like character, or as small-stalked tumours, causing complete or partial deafness, in accordance with the occluding area involved.

Surgical treatment is necessary, excepting in the case of a single-stalked growth (polypus), around which a thin piece of twine or wire can be fixed. It will then slough off.
