Dangerous foods?

hello! i was reading an article recently, that pancakes are harmful to dogs! i had never jeard this-but it caused me to wonder, and this is my question to you guys:
-is bread harmful to dogs?
i ask because my mom's Min-Pin loves bread & french fries...bit i've noticed when she has "alot" of bread, she becomes stressed out looking, especially in her hind quarters area.

i only know enough NOT to give her raw onions and chocolate.

any info? thanks!!

please feel free to e-mail me; otherwise, i'll look for replies.

I'd definitely cut back on the french fries, too, especially if they're commercially prepared. You don't really know what's in the frozen ones, and the fast-food fries are mystery foods.
