dogs: tueik management. 183 



very aged animals witli beautiful mouths ; but such, 

 sights, for the reasons which have been pointed out, are 

 unfortunately rare. The teeth of the dog, however, may 

 bo perfectly clean and entire oven at the twelfth year ; 

 and it is no more than folly to pretend that these organs 

 are in any way indicative of the age of this animal. 

 They are of no further importance to a purchaser than

 it and the permanent teeth, will inflame the gum, and
