Dogs pick up skills from watching other people. Hence, they may begin to believe, “Hey, flies are something to be afraid of,” and then they may experience fear themselves if they witness someone else feeling scared or disturbed by flies. 

It’s similar to how children may pick up fear if they witness friends or family members exhibiting it. Therefore, your dog’s fear of flies may have been picked up from seeing other dogs exhibit the same behavior.

10. Genetic Predisposition:

It’s possible that your dog’s fear of flies stems from their DNA, which they took on from their parents. Some dogs may be more sensitive to or afraid of particular objects, like flies, due to their breed or family history. It’s similar to how some individuals get a family history of height or a particular hair color due to genetics.
