CODY, a three-year-old collie dog who doused in flammable liquid and set on fire two weeks ago, has died.
The family pet suffered serious injuries after the incident in Maghaberry.
She was put to sleep on Saturday night.
Her owners posted on the Justice for Cody the dog Facebook page on Sunday that she had been getting worse from Friday and the vets had tried everything they could.
“We are all gutted, but we know she was suffering and was only going to get even worse,” the statement added.
Two people, arrested in connection with the attack, have been released on police bail pending further inquiries.
A police investigation is continuing.
PSNI Lisburn described the news as “tragic” on their Facebook page and said: “We would like to remind everyone that police are dealing with the matter, and two people have already been arrested.
“All evidence takes an amount of time to process, and when the investigation is complete the matter will be forwarded to the PPS.
“We would appeal for calm.”
