I got my dog tag. Well sort of. I called around NM (they don't carry it) and
Nordstrom's (the last necklace - it was a small) was on hold but it was purchased within the hour. So I had a light bulb moment and said to myself "Hey, let me get the key chain and remove the keyholder and links and put my own chain on!" I'm not sure what metal the Chanel dog tag is (I wouldn't want to get a sensitive reaction to it) so I'm going to buy a nice silver chain for it. Or else I'll make one (probably easier).
The chain link around the perimeter of the dog tag looks like a curb link, so it should be easy finding a chain. Maybe I'll get it in stainless or white gold, that way I won't have to polish it.
Here are the pics:
And I'll repost a picture of the new modified version when I remove the extra links.
