plaint will always be more or less subject to it, and, if he should happen to take distemper, ten 

 to one it will be of the enteric form. 



The treatment, then, will, it need hardly be said, depend upon the cause, but as it is generally 

 caused by the presence in the intestine of some irritating matter, we can hardly err by adminis- 

 tering a small dose of castor-oil, combining with it, if there be much pain which you can tell 

 by the animal's countenance from five to twenty or thirty drops of laudanum, or of the solution 

 of the muriate of morphia. This in itself will often suffice to cut short an attack. The oil is 

 preferable to rhubarb, but the latter may be tried the simple not the compound powder ; 

 dose, from ten grains to two drachms in bolus. 



If the diarrhoea should continue next day, proceed cautiously remember there is no great 

 hurry, and a sudden check to diarrhoea is at times dangerous to administer dog doses of the 

 aromatic chalk and opium powder, or give the following medicine three times a day :

This may be made into a bolus with any simple extract, and given three times a day. 

 Williams recommends the hyposulphite of soda in cases where there is much fcetor. This 

 seems to be a good plan, and, as there is no taste with the medicine, it may be dissolved 

 in water and given in the food or drink. Dose, from two to ten grains. If there be much 

 irritation of the rectum, with straining at stool, a compound lead and opium suppository may 

 be introduced at night, after the dog has lain down. 



The food is of importance. The diet should be changed, the food requires to be of a 

 non-stimulating kind, no meat being allowed, but milk and bread, sago, or arrowroot, or rice, 

 &c. The drink either pure water, with a pinch or two of chlorate and nitrate of potash in it, 

 or barley-water if he will take it. 



The dog's bed must be warm and clean, and free from draughts, and, in all cases of diarrhoea, 

 one cannot be too particular with the cleanliness and disinfection of the kennels. 



5. Dysentery. 



This is a far more serious complaint in the dog. Pathologically, it consists of an inflam- 

 mation, mostly chronic in the dog, of the colon and rectum, leading on to ulceration of the 

 mucous membrane. It is generally considered by medical authorities that the inflammation
