Final answer:
Connor Bradley's barking at people is not specifically mentioned, but examples from various texts show that dogs bark for many reasons, including alarm, aggression, and distress. The perception of dogs can change based on their behavior and whether they are restrained, which can affect their interactions with people.
Step-by-step explanation:
Connor Bradley's barking at people might be attributed to several reasons based on the excerpts provided. Dogs often bark as a reaction to their environment, emotions, or as a form of communication. In the stories, the bark of the dogs may signify alarm, aggression, or even distress due to illness, as indicated by the bull terrier with gastritis. Characters in the excerpts perceive the animals differently based on whether they are restrained or not. For instance, Joe Dagget sees a dog as good-natured despite others regarding it with fear when chained. Moreover, the showdown between two dogs, portrayed through their aggressive behaviors, demonstrates the innate territorial and combative instincts. The author's disapproval of unrestrained and untrained dogs causing disturbances is made clear through the use of negative language such as snarling and stomped. Lastly, illustrating negative consequences of canine misbehavior, an incident at an airport is described, where a supposed service dog attacks a guide dog, raising questions about the true service it provides.
