Big dogs, little dogs; black dogs, white dogs—all sizes and sorts of dogs are now carefully trained for use in the military service of France and Germany as messengers, scouts, and sentinels.

These "dog-children of the regiment" are not chosen from any special breed of dogs, because that would at once cause then to be recognized, and so become a target for the foe whenever seen.

These military dogs are chosen on account of the promise they give of "individual merit," and their education is begun as early as possible. All are trained to silence—a most difficult lesson, and only learnt by long and patient teaching. In fact, it is at all times difficult to insure obedience when music strickes up, for the training poodles, fox-terriers, and collies are sorely tempted to give vocal accompaniment. Dogs selected for this service are thoroughly children of the regiment. They are never allowed to associate with civilians, or to let any man wearing an unknown uniform approach them. They must not attack strangers, but are to keep at a respectful distance from all such. Thus their fidelity as letter-carriers is secured.

When on sentry duty they are taught to warn their human companions of the approach of any strangers within three hundred yards. Each dog has his regimental number on his collar.
