The contact of mangy dogs with healthy animals must be prevented, and covers, blankets, bedding, etc., which have been used by the affected animals must be sub- jected to a thorough cleansing by washing with hot solutions of soda and a high degree of heat.

It has a broad, scissor- like masticatory apparatus, a mobile anterior trunk, and three jointed maxillary feet.
