Those long spikes are just foolish - and they just play into that "bad breed" bushwa that's out there.
I'll have to find my photo of the big blue cat I had for many years, Gonzo, in the spiked collar I had made for him . . . It was a hoot to watch people's faces when I had him out on a leash with that collar on, but he'd earned it. There was a Doberman in the neighborhood that had bitten a couple of people and just generally terrorized everyone (he had a huge 6' chain link fenced in yard, but the owners thought it was funny to let him run loose
). Animal control wouldn't even pick him up. The dog liked to run up to the ground level window where Gonzo took his afternoon nap in the sun and throw himself against the window, snarling and barking. Gonzo got out one day - he had a plan; ambushed that sucker and tore him a new one. Dog stayed home after that. I would have felt a little sorry for him getting hurt, although it wasn't anything a few stitches didn't make right, but it probably saved his life since sooner or later someone was going to kill that dog.
And that's how Gonzo earned his spiked collar!
BG!!!! Glad to see you back!
