 much what we will ; and with the dog, his master from the 

 first, and always, is the princijDal factor. 



' Two extreme views have for a long period been enter- 

 tained in regard to the training of the dog : the one 

 that he is a wild, wayward creature to be '' broken," the 

 other that he needs no special correction if properly taught 

 from the first. Neither is quite correct. 



A puppy full of life tends to do exactly as his im-

 be consistent with his puppy. All caprice is fatal; it 

 utterly confuses and demoralizes the dog. 



Kemembering, as we indicated long ago, that the dog 

 is very like ourselves, we can suggest a few principles 

 for training that we think will meet the test of experi- 

 ence. The puppy at one period is like a young infant, 

 later like a two-year-old child, and at the best most dogs 

 never get beyond the intelligence of a young child in

 strong impulses but of little self-control. 



It is a well-established law of the nervous system, 

 that what has happened once is likely to occur again 

 under the same circumstances ; hence in the training of
