PREFACE TO THE THIRD EDITION. 
—_—_—>—_- 
Since the First Edition of The Dog was published in 1859, his 
varieties have been studied, and their points minutely described, 
by a great number of breeders to an extent which was never 
contemplated before that time. As a consequence, I have 
been enabled to define them most minutely in the present 
edition, and I think no sufficiently known breed, either British 
or foreign, is omitted from the list. In the Second Book little 
or no change has been attempted, for the simple reason that 
there is no occasion for it, since the various uses to which the 
Dog is put in this country by the sportsman and the dog-fancier 
have not been altered during the interval which has elapsed. 
The Third Book treats of his diseases, in which no great 
improvement has been effected since the publication of the 
Second Edition, and it is therefore printed as it then stood. 
It is with some considerable satisfaction that I now present 
to my readers my original work on The Dog brought down to the 
level of the present day.
