DISEASES OF THE MOUTH AND TONGUE. 53 



lolling side protrusion is a congenital deformity ; but it more 

 often occurs from injury, long-continued chorea, or debility. 



Symptoms. — The organ hangs generally from one side of 

 the mouth. Its condition rarely interferes with lapping, but 

 it gives rise to other undesirable results. From its protru- 

 sion and long exposure to air it becomes dry, coated with fur, 

 more or less indurated, and is, to say the least of it, un- 

 sightly. 



Treatment. — If the paralysis be of recent date, nux vomica 

 I to 2 grains, and ferri sulph. 5 to lo grains, twice daily, will 

 often, if not absolutely remove it, considerably reduce it. 

 Where the affection has been of long existence, the same 

 treatment is still applicable, with the addition of a small 

 seton in the submaxillary space ; but the latter cases are far 

 from satisfactory ones to deal with. The tongue should be 

 frequently placed back in the mouth, and, if possible, kept 

 there for a time ; this will tend to prevent, to a considerable 

 extent, the condition named from its long exposure to air. 



The diet is best composed of slops, and these should be 

 placed within reach of the animal, so that he may lap when- 

 ever inclination prompts him. 



PHARYNGITIS. 



Inflammation of the pharynx, unassociatea with other dis- 

 ease, is of rare occurrence in the dog. It is usually due to 

 an immediate exciting cause — as the lodgment of some for- 

 eign body, or contact of acrid and irritating substances. 



Symptoms. — A dry, irritable cough, such as would lead 

 «ne to suppose an effort was being made to dislodge some 

 irritant matter. The membrane has a congested and swollen 

 appearance; there is considerable difificulty in deglutition, 

 and the act, or attempt to perform it, is followed with retch- 

 ing. The throat is sensitive to external pressure, and cough 

 is easily excited by it.
