Smooth Fox Terrier
The dog must present a generally gay, lively and active appearance; bone and strength in a small compass are essentials; but this must not be taken to mean that a Fox Terrier should be cloddy, or in any way coarse--speed and endurance must be looked to as well as power, and the symmetry of the Foxhound taken as a model. The Terrier, like the Hound, must on no account be leggy, nor must he be too short in the leg. He should stand like a cleverly made hunter, covering a lot of ground, yet with a short back, as stated below. He will then attain the highest degree of propelling power, together with the greatest length of stride that is compatible with the length of his body. Weight is not a certain criterion of a Terrier's fitness for his work-general shape, size and contour are the main points; and if a dog can gallop and stay, and follow his fox up a drain, it matters little what his weight is to a pound or so.
