Pepper is Strange

I rescued Pepper when she was about a year old (although sometimes I'm pretty sure she's the one doing the rescuing). I don't know what her previous owners did to her other than leave her in the TRAC parking lot, wandering around filthy, without a collar, and almost 20 pounds under weight. She obviously had training though, abuse too. She already knew sit and down and was house trained. But she also has some very strange quirks. Did she have them before she was abused and abandoned? Or are her quirks why her previous owners ditched her?

Pepper eats everything. Well, almost. But she does eat a whole lot more things that I've never heard of other dogs eating. She eats lettuce, onions, jalapenos, apples, bread, cat food. She knows how to eat chicken bones without hurting herself. She doesn't like lemons/limes, nor does she like some of the spicier Asian dishes. But she does like Pam. As in the cooking spray. She goes bonkers for it. Whenever I reach for the can, she comes running. It's my new parlor trick. I can spray it on her nose or paw and she's a happy girl for 10 minutes. She knows the sound of it too, and comes running when I use compressed air. She even lets me spray air in her face for quite a while before she realizes it doesn't taste like anything. It's hilarious.

My poor pup also has some not-so-funny quirks. She's terrified of the fly swatter, as in cowers behind me and whimpers until it's out of sight. She  does the same thing around snowmen. Pepper is also afraid of knives being sharpened, the coffee pot grinding beans, the chime on the washing machine, and any flashes of light (e.g. sparkly jewelry, flashlights, sun reflecting off windows). When she's agitated she licks the walls. So much so I can see brown areas. She's even licked the lacquer off one of the cabinets. *sigh* my poor, sweet puppy, I love her so.
