curl under or turn to one side; in one case observed the claw was flattened 

 like the nail of a man. 



Treatment. — Fomentations and poultices, painting the affected toes 

 with tincture of iodine. It generally is best to repeat this application 

 two or three times. If the claw is purulent, it must be treated with an

 claw is loose, it must be removed, taking care not to injure the matrix

 the claw. Frick has prevented the further extension of the disease by 

 intraparenchymatous injections of tincture of iodine, the internal 

 administration of Fowler's solution, and touching the affected claw with 

 nitrate of silver. The nail can be protected by means of the shoe illus- 

 trated in Fig. 125. 



Contusions and Wounds of Pads. — Contusions of the pads are most 

 frequently ol:)served in sporting dogs, particularly in animals that have 

 not been used for active work or when they are first trained, going over 

 stubble fields, or in dogs going over long distances on snow or frozen roads. 

 Occasionally we find extensive oedema and sloughing caused by the 

 presence of an clastic band placed around the foot or toes by a child in 

 play. 



The animals walk very stiff, or in some cases it may be almost 

 impossible to get them to walk. The pads are hot and painful on 

 pressure; if the pad is very much worn the dark external skin is worn off
