INTERNAL PARASITES OR WORMS. 351 



Nervous. Convulsions, twitchings in sleep, chorea, 

 paresis. 



The general economy suffers, as shown by emaciation, 

 dullness, debility, etc. 



Round worms are much more common than tape- 

 worm, which is rare in puppies, from which the former 

 are seldom absent in pure-bred dogs. 



Diagnosis. General lack of vigor, unthriftiness, with 

 symptoms of imperfect digestion, especially bloating, 

 should in a young dog suffice to lead to treatment for 

 worms in the absence of any other obvious cause. Much 

 attention to the anal region suggests thread-worms; 

 marked emaciation, with a ravenous appetite, tape-worm. 

 The segments may be seen at times in the stools. 



Prophylaxis. The prevention of worms has been al- 

 luded to under treatment of the brood bitch. Pup- 

 pies get the eggs from their dam; but if one dog in a 

 kennel has worms, it is easy to understand how they may 

 be spread by dogs walking through the stools, licking 

 each other, etc. 



Milk can not convey the germs of worms except by 

 their getting into it after it leaves the cow, which is not 

 very likely ; but milk does, in large quantity, tend to relax 

 the digestive tract, produce an excess of mucus, and, in a 

 word, favor an environment in the intestine suitable to the 

 development of worms. 



Continuous sloppy food for puppies is therefore a mis- 

 take. 



Meals of dry biscuits, bread-crusts, etc., are beneficial 

 in clearing out mucus and ova of worms and begetting a 

 better tone in this region.
