2 1 8 The Management and Diseases of the Dog. 



LICE. 



These insects, though not giving rise to the same amount 

 . of irritability as the former, are, nevertheless, troublesome, 

 and perhaps more annoying from the fact that they are 

 usually an indication of uncleanliness. They are generally 

 found in greater abundance about the back and posterior 

 parts. They are hatched from eggs or nits attached to 

 the hair. The dog-louse produces no irritation on the 

 human skin. 



Treatment.— The white precipitate powder, brushed into 

 the coat, or the ointment rubbed in the skin, and removed 

 in the course of five or six hours, forms the most effectual 

 treatment for their destruction and removal. 



TICKS. 



The dog-tick {Ixodes ricinus) is uncommon compared 

 with the two preceding parasites. The creature causes 

 considerable irritation to its host, and, from feeding on the 

 blood by suction, gives rise, where they exist in any num- 

 ber, to debility. 



Treatment. — Forcible removal, and dressing with mer- 

 curial preparations. ,
