Dog age calculation



A dog has a very visible mark in his teeth, well as a horse, which mark does not disappear totally until he is very near or full 6 years old. Look to the 4 front teeth, both in the upper and lower jaw, but particularly to the teeth in the upper jaw, for in those 4 front teeth the mark remains the longest. At 12 months old you will observe every one of the 4 front teeth, both in the upper and under jaw, jagged and uneven, nearly in the form of a fleur de lis, but not quite so pointed at the edges of the jags as a fleur de lis is. As the dog advances in age these marks will wear away, gradually decrease and grow smoother and less jagged every year. Between 3 and 4 years old these marks will be full half worn down, and when you observe all the 4 front teeth, both in the upper and lower jaw, quite worn smooth and even, and not in the least jagged, then you may conclude that the dog is nearly if not full 6 years old. When those marks are worn quite flat and even, and those teeth quite level and even, you can no longer judge the age of a dog. Many huntsmen and game-keepers ignorantly look at the side and eye-teeth of a dog; there are many dogs not 2 years old which have had the canker in the mouth, with hardly one sound tooth in their heads.
