Since Friday morning, when we first posted the story of Kate K and her dog Coco — who is recovering from being poisoned in her own yard — the comment thread brought two other nearby residents forward with stories about dog poisonings – and that has animal authorities investigating whether these cases might be linked (at Kate’s request, we e-mailed those two commenters to be sure they saw her note about contacting the investigator). It’s also brought two citywide-media reports – we want to thank the Times for crediting WSB and those commenters in its report today (here’s the link); the other report didn’t. Thanks also to those who shared advice on emergency vets.
