194 "^f^^ Management and Diseases of the Dog. 



With regard to the further treatment of canker, I quote 

 the following from the "Veterinary Journal," Sept., 1875, 

 p. 216: 



TREATMENT OF ULCERATION IN THE EARS OF A DOG 

 BY COCULET. 



"The disease vulgarly known as 'canker ' in the dog Is 

 frequently most troublesome and unsatisfactory to treat, 

 for several reasons. In the ' Recueil de Med. Vet^rinaire,' 

 Coculet recommends, as a very successful method of dealing 

 with these auricular chancres, the application of some blis- 

 tering ointment or liquid over the external surface of the ear. 

 The preparation he employed was tincture of cantharides 

 forty-five grammes, tincture of oak galls ten grammes. This 

 was applied once every two days, and by its influence the 

 intolerable itching which accompanies the disease was 

 allayed, and a smart but inconvenient pain substituted. 

 The animal no longer shakes its head, nor scratches the 

 ears with its paws, and the chancres soon disappear." 



SEROUS ABSCESS. 



It not unfrequently happens from the violence applied in 

 canker to the inflamed organ by the dog himself, or inde- 

 pendent of canker existing, from blows or bruises, that an 

 infusion of serum takes place between the integument on 

 the inside of the ear and the cartilage underneath, giving 

 the organ a peculiar, dropsical, baggyappearance. In such 

 a case it is best to open the sac at its most dependent part 

 with a lance, making a free incision, and evacuating the 

 contents. In a short time the wound will heal, and the ear 

 assume its natural condition. There is no necessity to in- 

 duce suppuration ; if nature establishes it, well and good, 

 and it must then be treated as a suppurating; sore.
