It was love at first sight when Yvette Colomb spotted Elsa on a greyhound adoption site.

Originally a racing dog, Elsa was almost euthanised before Colomb rescued her and gave her a second shot at life, only to see her horrifically poisoned a few years later.

It was 2020 and they were on a property about an hour north of Sydney when Elsa suddenly started to vomit.

Colomb immediately put Elsa in the back of the car and raced to Sydney, where her daughter took Elsa straight to the emergency vet.

"I remember I looked at her and it was the last time I looked at her before she was quite disabled," Colomb told 9news.com.au.

By the time Elsa arrived at the vet, she'd vomited again, suffered a seizure and had to be put on life support.

That's when the vet called Colomb and revealed her dog had been poisoned.

Elsa had accidentally ingested sodium fluoroacetate poison baits, better known as 1080.

The poison is used across Australia to cull foxes, rabbits, wild dogs and feral cats by applying it to food items which are left out for animals to find.
