DISEASE IN GENERAL 22? 



against a particular infection. So far it has been possible to 

 prepare reliable immunizing products only against those diseases 

 that produce rather powerful toxins and that run a more or less 

 acute course. 



An attempt to confer immunity is not always successful. In 

 some cases the animal may succumb to the disease after it has 

 been treated, or die as a result of complications of the disease. 

 This is due to (1) the animal being already infected when treated ; 

 (2) insufficient or impotent immunizing agents; (3) improper 

 administration of the immunizing agents; (4) infection with other 

 germs of disease after the immunizing treatment has been given. 



The veterinarian has certain legal responsibilities when he

 service as may be needed until the case shall be terminated, 

 either by the death or recovery of the patient, or by the proper 

 severing of the relationship existing between himself and the 

 owner. 



4. That he will employ approved methods of practice. 



5. That he will use due care and diligence. Moreover, unless 

 especially provided, the veterinarian will not be deemed to have 

 guaranteed a cure. 



The owner of the sick animal agrees on his part: 



1. That he will follow all reasonable directions of the veteri- 

 narian and render such assistance as may be possible. 



2. That he will pay the veterinarian such reasonable fee as 

 would be approved, considering the services rendered, by the 

 customs of the community. 



THE TERMINATION OF DISEASE 



Convalescence is the period between the removal of actual 

 disease and recovery of health and strength. During this period 

 it is highly important that the animal does not overdo, for its 

 strength and power of endurance are reduced. Without doubt,
