176 Life and Love. 



that infantile falsetto being changed to a manly 

 bass. He also grows quarrelsome, and shows an 

 inclination to demolish strange dogs. As a puppy 

 he is friendly, and shows little discrimination in per- 

 sons, liking every dog that does not offer to bite 

 him, and delighted with the caress of any human 

 being. 



Later, he is less general in his friendships. He 

 discriminates, and offers to fight certain dogs, dis- 

 carding all overtures of peace; he becomes highly 

 individualized, has distinct likes and dislikes for 

 people, and develops the feeling of obligation 

 which makes him guard his master's property. If 

 he comes of hunting-stock he expresses more defin- 

 itely his desire to hunt, and the method of hunting 

 he is best able to employ. 



From a puppy like all other puppies, he be- 

 comes a distinct individual. 



As a rule, the male is most profoundly affected 

 by maturity, and everywhere shows the greatest 

 amount of change. 



As the individuality increases, the power to 

 change diminishes. 



During his unformed puppy stage the dog learns 

 easily, and then can be trained to many habits use- 

 ful or pleasing to man. Later, the power to change 

 lessens, that is, the groiving power is in abeyance, 

 the ideas and habits have become fixed, the direc- 

 tion of the individuality is determined, and it then 

 is more difficult for him to learn new ways.
