Helping Paws: Dogs That Serve (Hello Reader!® Level 4)
The author describes roles of canines long ago (such as the use of dog power to transport goods) and in contemporary times: from herders and hunters to police dogs, military dogs (including scout, messenger, and even parachuting dogs), search-and-rescue dogs, and traditional service dogs (the training and role of guide dogs, hearing dogs, canine assistants, seizure dogs, and therapy dogs). Dogs, dogs, dogs!
