This was probably 30 years ago. Now, they weren't eating dogs so much as some redneck's poor pooch tried to eat one and got it stuck in its throat, wot with the various spines, and kicked the bucket. I remember video of one wriggling across what looked to be a golf green. (It's a whole new kind of water hazard, there, Chet. You said it, Bob. Now over to Jan with the Weather.) Kind of a shame, since they're neat critters, but on the other hand, they would end up all over the place if they were unrestricted.
