lol Renee, I was thinking, it's something *I* would wear.
Wouldn't put one on my BCs, their fur would hide it. Ripley has some spiked leather gear, but the spikes are blunt so he doesn't hurt himself. I think it looks ugly on a Doberman or Rottweiler - honestly, my favorite collar on a large, sleek dog like a Dobe is a thin chrome-plated show chain. There's something magnificent about a large, muscular dog that has the self control to walk on a thin chain. I find it much more impressive and imposing than a brute of a dog hitting the end of a spiked collar.
If I had a LGD it would certainly wear a wide, spiked collar to protect its neck.
