4i8 The Management and Diseases of the Dog. 



ANTIMONY. 



The form chiefly used in canine practice is that known as Tartar 

 Emetic, and is nearly exclusively administered for emetic purposes. 



Actions and Uses. — Alterative, antiphlogistic, sedative, and 

 emetic. Externally, it is a counter-irritant, and when ' absorbed 

 produces the same effects in the dog as when administered by 

 mouth. 



Antidote. — Tannic acid. 



Doses. — As an alterative, antiphlogistic, and sedative, -^ to 2 

 grains. 

 Emetic, I to 3 grains. 



NUX VOMICA— STRYCHNINE.

 dogs. 



Actions and Uses. — In excessive doses, a deadly poison. Medi- 

 cinally it is a tonic and nerve-stimulant, being especially valuable 

 in cases of paralysis, chorea, and amaurosis. Excessive doses 

 produc*; general rigidity, trembling, spasmodic muscular twitchings, 

 extending to the glottis, diaphragm, and muscles of respiration, 

 hence death by asphyxia. 



Post-mortem Appearances. — Redness and inflammation of the 

 stomach and intestines (more particularly present when the 

 animal has survived some time). In some cases, engorgement of 

 the lungs, right side of the heart, and large bloodvessels ; in 

 others, an absence of blood in the latter, rigidity of the involuntary 

 muscles, flaccidity of the voluntary ones. Congestion of the 

 brain and membranes of the spinal cord. For some hours after 

 death the body is stiff and straight, the limbs rigidly extended, 

 the head thrown backwards towards the spine, the ears erect, and 

 the tail carried straight out. 



Antidotes. — Decoction of tobadco ; extract of hemlock; chloro- 

 form. 



Doses. — Nux vomica pulv., 2 grains. 



Nux vomica extract, J to i grain. 

 Strychnia, 3'^ to ,„ of a grain.
