262 DOGS : THEIR MANAGEMENT. 



time prior to the attack, and the matter vomited has a 

 peculiarly disagreeable and acrid odor. The dog does 

 not again consume that which the stomach has thrown 

 off, but sneaks away dejected, and afterwards seems dull. 

 Sickness will occasionally continue throughout the com- 

 plaint, but in general it departs as the disease appears. 

 Thirst, however, is always present ; and there is also a 

 disposition to seek cold things and places. The pulse is 

 quicker, but not stronger, and hardly at first less thin 

 than during health. There is no pain on pressure being 

 applied to the abdomen. The membranes of the eye are 

 not injected ; they may be a little deeper in color than is 

 strictly natural, but occasionally they are the reverse. 

 If, however, the anus be gently forced open, so as to ex- 

 pose the terminating surface of the rectum, the mem- 

 brane there will be found more red, and perhaps less 

 clear in tint, than it ought to be ; and the presence of 

 purgation, attended with a violent resistance to the ad- 

 ministration of clysters, will leave no doubt as to the 

 character of the affection. 



In the chronic form, the membrane of the eye is pal- 

 lid ; the nose often moist ; the breath offensive ; the 

 appetite ravenous ; the pulse quick and weak ; the anus 

 inflamed ; mostly protruding, and usually disfigured by 

 piles ; the fasces liquid, and of various hues ; sometimes 

 black, occasionally lighter than usual, very generally 

 mixed with much mucus and a small quantity of blood, 

 so that the leading symptoms are those of weakness, 

 accompanied with purgation.
