252 THE DOG IN DISEASE. 



It always indicates, when purely functional, that the 

 food is unsuitable either in quantity or quality, or that the 

 stomach is unfit to receive it, and so is better without it. 

 The dog frequently, in warm weather, eats grass and 

 causes vomiting, and thus in a way regulates his own di- 

 gestive tract. 



As a rule, when a dog is seen to vomit he should 

 either be left without food for a time or have his diet

 the digestive organs, vegetable bitters as gentian, quassia, 

 cinchona, etc. are useful, especially in the form of the 

 compound tinctures. Nux vomica, carefully watched, is 

 excellent. A change in the feeding to raw meat only for

 some opinion by watching the stools, this must be treated. 

 The color and consistence of the stools of the dog vary 

 with the food. Meat causes them to be dark ; a mixed 

 diet some shade of yellow. They may be very hard and
