From the Archives of Dog World: Enjoy this all-access pass to dog history from the pages of the longest published dog magazine. This content remains in its original form and reflects the language and views of its time. Health and behavior information evolves and only the most current advice should be followed.
The milk-teeth or first set all come in the first three or four weeks after birth and give way to the permanent set by the end of the sixth month. In the first two or three years of his life the dog’s teeth are are usually clean, glossy and beautiful, but the continuance of this condition depends much upon his good health. Still no little is owing to the feeding and care of the dog, and usually the after the third year more or less tartar collects about the necks of the teeth, and the teeth decay and they become a great nuisance to the dog and his owner. However, in good circumstances where the dog lives naturally, he lives outdoors and has proper food and exercise. The teeth usually serve him to the end of his life without trouble, offense, or decay. After the dog reaches his fifth or sixth year especially, little can be told of his age from the appearance of his teeth. There is not much to be said about the treatment of the dog’s teeth.
Supernumary teeth, which sometimes appear, should be extracted if they occasion deformity or decay, otherwise let them alone. Dogs that live in cities, in warm houses, and are fed on all kinds of artificial and concentrated foods, in season and out of season, suffer greatly from carious teeth as do human beings.
