Answer:
I am the kind of dog that chases anything red.
Part carbon part water I am poison to the fishes. Many falsely claim my name I am the pause that refreshes.
I am like thunder in your cranium
I sleep by day, I fly by night. I have no feathers to aid my flight. What am I?
I hide in a dark tunnel awaiting my time. I can only be released by pulling back. Once released I may do unstoppable damage.
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
