A greyhound trainer who cut off part of a dog's tail without pain relief and then raced the animal while the wound was gangrenous has been allowed to continue training.

The greyhound Racing Appeals and Disciplinary Board's decision has been slammed as alarmingly lenient, and used as evidence that the scandal-plagued industry still needs urgent reform.

The dog, named Super Ballotelli, was put down by a veterinarian more than a year ago, when the dog was not yet three years old.

The Heathcote trainer, Jason Formosa, was named 2016 Trainer of the Year in Shepparton on Friday night – the second year in a row he has won the award– despite being fined $5000 and having a six-month licence disqualification fully suspended by the Greyhound Racing Victoria's Racing Appeals and Disciplinary Board.
