My dog used to be afraid of…
The microwave
Kitchen implements
Floor lamps
Flashlights
She got over the first 3 when I moved and she forgot to be afraid of them (my brother scared here with this stuff when she was a puppy). The flashlight thing she apparently got over just last week when she discovered the fun of chasing a flashlight beam in the snow. I have no idea why she was afraid of it in the first place.
However, she is very very afraid of the Windows Shutdown sound. I have had to disable it on all of my computers. If she hears it at my mom’s, she runs away.
Like justrob’s german shepard, Dolly has something she’s not so much afraid of but extremely angry with. The Goodyear Blimp. We live between Akron and Cleveland, and whenever the blimp is going from its hangar to Cleveland, it goes over our house. Dolly will hear it coming while inside, bark crazily to go outside, then bark her head off at the blimp until she “chases it away.”
