Tom, Pepper, and Trusty by L.T. Meade

The two little boys and the dog ate their supper in perfect silence, the only noise to be heard during the meal being the crunching of three sets of busy teeth. Then, the fire being quite out, the children lay down on a dirty mattress in a corner of the room, and Trusty curled himself up at their feet.

However lazy Trusty might be in the daytime while the fire was alight, at night he always assumed the character of a protector. Let the slightest sound arise, above, around, or beneath him, and he raised a bay, cracked it is true, but still full of unspeakable consolation to the timid heart of little Pepper.
