I agree, but luckily my terrier apparently doesn't give a poo about fireworks. Probably nobody jad thrown fireworks at him yet. My inlaws' country dog (also a fox terrier mix with the same temperament) growls at people, especially teens, smelling of powder and barks at fireworks and motorbikes. Good thing he's not a Malinois to nip those teens and chase the motorbikes. So it'a more of a nature vs. nurture thing.

dog behavior is strictly a reflection of their owner

[borski]

Given that most dogs are adopted from shelters, dog behavior is often a reflection of early upbringing. The current owner can train and teach their dog, but some behaviors and fears set in fairly early on.

Moreover, many dogs are beaten or worse when they’re young, and undoing that fear and trauma is a lifelong (for the dog) struggle.

Thus, dog behavior is far from “strictly a reflection of their [current] owner.”
