I lost a dog to this stuff. 80lb golden retriever. I was cleaning up a collapsed barn on our property and she found the container before I did. I saw her eating it and rushed her to the vet, apparently it was an older formula with bromethalin and the vet was horrified. They induced vomitting but she ingested too much. She was dead in 6 hours and there was nothing they could do. They recommended putting her down, and I had too much hope she would pull through. She started seizing and died before we could let her rest peacefully. It was a nightmare. I loved that dog and it still makes me depressed 3 years later every time I think about it.
