It is sometimes necessary with sheep dogs, dogs used for catching deer, and dogs in the habit of biting and fighting, to cut the tusks level with the incisor teeth. This is best done with a pair of strong bone or wire nippers. The operation apparently causes very little inconvenience or pain, for the dog is always ready to eat immediately afterwards. =Teeth, Tartar on the=: _Symptoms_: Dogs always fed on soft food and never having anything hard to eat, get their teeth covered with brown-coloured tartar early in life, even sometimes before two years old. If this is not from time to time removed, it continues to increase, until at last the whole tooth becomes thickly encrusted, and to such an extent, in old pet dogs particularly, that the mouth is unable to be closed. As the result of the tartar, the gums become swollen, inflamed, and tender; they recede from the neck of the teeth, which become loose. A dog with teeth in this state is always dribbling, and eats with difficulty, and the breath is often most offensive. _Treatment_: Dogs should always be encouraged to eat something hard daily—a piece of dog-biscuit does very well; if this is refused, a hard bone, one that cannot be eaten, should be given to gnaw. This, of course, is only a preventative, and when regularly attended to, the teeth and gums remain good and sound for years. When once tartar has accumulated, nothing will remove it but scraping; which should be done regularly two or three times a year, and if this is done, and the teeth daily cleaned with an ordinary tooth-brush, moistened with warm water and a little of the following powder sprinkled on it, they will keep clean and white, and the breath sweet so long as the dog lives:— _Recipe: Tooth Powder_: Powdered Boracic Acid, 10 grains. Camphorated Chalk, 1 ounce. Well mix. Removing the tartar from a tooth that is somewhat loose does not tighten it, though it preserves the tooth, and for a time often prevents it becoming looser. It is impossible to remove tartar from a very loose tooth, and for the dog’s comfort, it should be extracted at once. =Temperature=: To know the temperature of the body is very important in treating disease, more especially in cases of distemper; for it is a fact that so long as a dog does not have a high temperature when suffering from this complaint, the attack is not a severe one, and the dog, bar accident or relapse, has a good chance of recovery. When the temperature is high, say, 104 or 105, and continues so for some days, the case is always a serious one, and if it continues, complications, especially those of the nervous system, are almost sure to ensue. These remarks not only refer to distemper, but to all other diseases in which a high temperature is one of the symptoms; as, for instance, inflammation of the womb, blood poisoning, pneumonia, peritonitis, diseases of the brain, formation of abscesses, etc.
