I find it kind of odd that they used "may've" in written form. That isn't a very commonly used contraction in written material.
Maybe they were too lazy to write "may have" instead of "may've"?
Sure, you don't want the poor animal relying solely on its owner's backup gear. I'd call PETA if I see an irresponsible dude walking his dog with some backup light!Well I hope those that have been using the E1B while walking their dog realize that they should be using a primary illumination tool like the C2, not a backup device.
