4 The Management and Diseases of the Dog. 
For those used in sport or kept on the chain, especially 
the former, flesh-meat used with discretion is suitable. 
Paunches or mutton are best adapted; the former should 
always be thoroughly washed, otherwise worms or their 
larve, which are frequently present, are likely to be 
swallowed, and develop in the dog into large tape-worms 
(see chapter on “‘ Internal Parasites”); horse-flesh is heat- 
ing, causes the animal to smell strong, and is a great pro- 
ducer of worms. Liver cooked is like so much leather— 
indigestible and innutritious; and, from its liability to 
flukes, which in the dog develop into the taniz proper, is 
_also objectionable raw. Greaves I have observed frequently 
give rise to diarrhcea, probably from the amount of tallow 
often retained, and other foreign matters—as maggot-skins, 
mineral substances, and portions of bone. 
Sheep-heads, trotters, and ox-noses form a_ highly 
nutritious and valuable food, especially for invalid dogs ; 
boiled down, they form a glutinous jelly, of which dogs are 
particularly fond. Whichever kind of flesh-meat is used, 
meal should form the basis, and none is better than the 
coarse Scotch oatmeal, thoroughly cooked. 
Bones are of great value to the Dog—The dog has a 
natural fondness for bones, independently. of which they 
are of great value to him. One should always be allowed 
at least once or twice a week. They assist in cleansing 
the teeth and aid digestion. The animal’s instinct would 
appear to teach him this; for however good and savoury 
the meal may be, if there be a bone in it, he will imme- 
diately pick it out, strip it of its meat, if there be any, and 
store it safely away for after-use. It is best, however, to 
give bones after a meal; otherwise, when hungry, they are 
apt to eat as much of the bone as possible, to their own 
injury ; as portions may get lodged in the cesophagus, and 
give rise to asphyxia, or, from being too hard to digest, 
cause gastric or intestinal irritation. 
Biscuits——Biscuit food has now largely supplanted the
