Toy dogs’ teeth go wrong much quicker than bigger ones, more especially Yorkshire terriers, spaniels, and pugs. I have seen many a Yorkshire terrier three years old with half the teeth gone, and the remaining ones covered thick with tartar. The condition, in a great measure, is due to feeding, but some bad teeth are no doubt also hereditary. All dogs should have something hard to gnaw every day, either a hard dog-biscuit or bone—not game or poultry bones, of course, or cutlet or chop-bones, for these are more dangerous than game bones, but a good big bone; for small dogs a leg-of-mutton bone, and for large ones a marrow or some other such bone. Puppies, from the time they are weaned, should be given bones, as this often prevents their eating stones and other indigestible articles. Tartar should never be allowed to remain and accumulate; it irritates the gums, and causes them to recede, and then the teeth soon get loose. Therefore, in all cases where there is a disposition for tartar to collect, it should be scraped off from time to time. As a rule, if it is done about three times a year, the teeth may be kept fairly clean. Once the teeth are cleaned, they may be kept white if people will take the trouble to brush them daily, using some powder. The best kind I know of is carbolated eucalyptus powder, as prepared by Messrs. Hucklebridge, of 116 Ebury Street, London, S.W. I mention the name and address, as I do not know of anyone else who makes it, and carbolic powder is not suitable for dogs. The scaling or scraping of the teeth may be done with the point of a penknife or an ordinary steel nail-cleaner, but one must be careful in using these instruments or the gums may be injured. To lessen the risk of doing so, it is much better to buy a proper instrument, which can be bought for half-a-crown at a place like Krohne & Sesemann’s, Duke Street, Manchester Square, London, W. Loose teeth should be removed, as they only do harm when left, besides causing inconvenience to the dog whilst eating. Sometimes it becomes necessary in very old dogs to remove all the teeth; and when the food is given soft, and cut up small, they appear to do very well without them, and their breath is certainly a good deal sweeter. Occasionally an abscess forms at the root of the large upper molar tooth; the face swells just under the eye. The abscess, after a few days, generally breaks. The swelling should be fomented with hot boracic lotion, but to effect a cure, the tooth must be removed. It is a difficult one to extract unless it is loose, and no amateur should attempt to do it. An anæsthetic ought always to be given. =Teeth, Cutting the Tusks=:
