especially fitted for cutting, as 

 may be noted if you watch the 

 way a dog gnaws bones, first 

 gnawing with the back teeth on 

 one side and then on the other. 

 In fact, a dog does not seem to 

 need to chew anything but simply 

 needs to cut his meat in small

 glance slinks away. When excited 

 he barks and every bark expresses 

 high nervous tension. 



Almost all dogs that chase their 

 prey bark when so doing, which
