Dog 'treated in a way no dog deserves' found in Melbourne park

A pet dog has been left fighting for life after she was found abandoned in a park in Melbourne's north-west.

Bella the American Bulldog was discovered tied to a tree by a member of the public in Diggers Rest last Sunday.

She was emaciated and suffering significant injuries that appeared to be inflicted maliciously, the RSPCA said.

"We found Bella near Jackson's Creek behind a small hill, nestled in bushes littered with garbage and debris. It's a miracle she was found at all," Inspector Karen said.

"She's clearly suffered abuse and has been treated in a way no animal deserves. But despite the immense trauma she has been through, she's an extremely sweet, good natured dog. Far too forgiving considering her experience."

The RSPCA believes Bella was dumped between Friday 8 and Sunday 17 November, however it's most likely it was between last Friday and Sunday.

"We're asking anyone who recognises Bella or has information about this incident to make a report and please come forward to help us identify the person or person's responsible for this act of cruelty," Inspector Karen said.

Anyone with information is urged to call 03 9224 2222 or visit rspcavic.org to make a report.
