In Dogs — Follicular mange, caused by Dermodex foliculorum, var. 

 canis, attacks head, neck and limbs, invading hair follicles and 

 sebaceous glands; very difficult of cure. Sarcoptic mange, caused 

 by Sarcoptes squamiferus, attacks head, chest, belly, elbows, root of 

 tail and claws, and spreads to whole body. Readily cured. Isolate 

 to prevent spread to man or dogs. Apply muzzle and clip hair 

 over lesions. In sarcoptic mange, Peru balsam and sulphur oint- 

 ment (3i-5i)> or 1 ysiTt each, liquid tar and soft soap, and 8 parts
