Answer:
I am the kind of dog that chases anything red.
I'm sometimes white and always wrong. I can break a heart and hurt the strong. I can build love and tear it down. I can make a smile, but more often bring a frown. What am I?
I am taken from a mine and shut in a wooden case from which I am never released. Yet I am used by almost everybody. What am I?
I am whole but incomplete. I have no eyes yet I see. You can see and see right through me. My largest part is one fourth of what I once was.
I am sometimes referred to as chips
No matter how little or how much you use me, you change me every month.
