INTRODUCTION. 299- 



These dogs are also particularly subject to morbid 

 affections of the liver, and when suddenly exposed 

 to cold, or cold and wet, are very liable to be at- 

 tacked with inflammatory diseases. A scanty 

 allowance of food, and not in proportion to his 

 exercise, is likewise very injurious to dogs ; the 

 functions of the body are thereby languidly per- 

 formed and the dog loses his vigour, and is fre- 

 quently affected with the mange. These animals 

 require to be fed on something substantial ; for 

 example, if you give a dog as much strong broth 

 as he will take, it will not support life ; — on the 

 contrary, another dog shall have nothing allowed 

 him but the meat from which that broth was 

 made, and shall do well, although the meat be 

 boiled to dryness. Exercise, keeping the kennels 

 very clean, and well ventilated, and giving them 

 a proper proportion of animal and vegetable food, 

 according to the nature of their exercise, and 

 likewise occasionally physicking them, are all ab- 

 solutely necessary to preserve dogs in health and 

 vigour. It will be proper here to mention, that 

 all the recipes in this Treatise are intended for 

 middling-sized dogs, and their strength may be 

 diminished or augmented according to the circum- 

 stances of the case.
