Oh yeah! That's the ticket because after all the dogs are evil and deserve to die a painful death. It doesn't matter to you how they were bred or how their owner's treat them. Let's blame the dogs for selective breeding and owner idiocy.
We have a largish population of feral cats. I don't feed them or encourage them to stick around my home. I wouldn't make them suffer the pain anti-freeze causes just because they occasionally destroy some of my plants by their digging or because they kill some of the songbirds I like to feed. Yeah, they're pests because they're feral. It's not their fault though and if nothing else they deserve a quick, painless shot to the head.
By the way, I'm in no way inferring our feral cats would be equal to an animal which had attacked someone. I just don't believe in torture.
But hey, whatever works for you.

Way back in the 1960's we had a pet cat that died. We found that our landlady was mixing d-con with hamburger and setting it out "for rats" she said.

I have never set out anti-freeze. I found lead poisoning works well. namely .223 or .357 mag.
