who rehabilitates abandoned dogs and is looking after Cupcake, said she was furious at those responsible.

The animal's teeth had been filed back to prevent it damaging its opponent. She also had scars around the neck, and an injured eye.

"Kay", who rehabilitates abandoned dogs and is looking after Cupcake, said she was furious at those responsible.

"To victimise and torture a vulnerable creature to try to create a status or an image they want to be proud of is pretty despicable," she said.

"Man up - if you have a lust for fighting go out and fight yourself."

"Kay" is using a pseudonym because she is concerned the dog's former owner will track it down.
