RSPCA NSW has reached out to the public in an effort to find out more information about a dog that was dumped in Silverdale last week.
The injured dog was found on the corner of Silverdale and Eltons Road, Silverdale by passing motorists.
The people who located the dying canine posted about her injuries in a viral Facebook post which has now been shared nearly 2000 times.
"I stopped for what we thought was a dog who may have been hit by a car near the corner of Silverdale and Eltons [Road], Silverdale," the post said.
"The poor dog was alive, with her mouth taped shut and clearly visible bloodied fresh wounds... we were able to remove the tape and get her to the vet, but she had passed away by the time we arrived.
"We at least hope in her last moments she felt some comfort and warmth."
Now the RSPCA has launched a public appeal on Facebook for information about the dog.
"RSPCA NSW is urgently appealing to members of the public for information after a dog has died under suspicious circumstances in Sydney's south west over the weekend," the post said.
"The dog was found on the side of a road in Silverdale with numerous injuries to her head and body and her mouth taped shut.
"She had no microchip or collar."
RSPCA NSW said it was actively investigating this incident
"The dog has been taken into our custody and we are still searching for her owner," the Facebook post said.
"A post-mortem examination of the body is being conducted to determine the cause of death and gather forensic evidence.
"RSPCA NSW is appealing to anyone that may have first-hand information about this incident to come forward and make a confidential report."
