They are softer, wider apart and get more so with the o;rowth of the jaw, smaller and more pointed, than those that will succeed them. The incisors of the dog are very characteristic, owing to their cusps or points, usually three in number. The shedding of the teeth begins at about the four- teenth to the sixteenth week; but in this case the central incisors are the first to be renewed, and the upper molars. Fig. 11.—Anterior View of the Incisors and Canine Teeth in a Year-old Dog (Chauveau). are cut before the lower. Usually the canines appear soon after, but they are more frequently delayed than the other teeth. However, there is a good deal of difference, often in even the same litter, as to the exact age at which the renewal begins, the teeth are all shed, and the permanent set is completed. Usually the dentition is complete before the fifth month, but in the smaller breeds the completion of the process may be delayed till the sixth or eighth month. There is no increase in the number of incisors or canines, but the molars in the second set are twelve in the upper jaw (occasionally fourteen) and fourteen in the lower, making the total number of teeth forty-two, as in- 13.
