A MAN mauled by a pack of savage dogs has lashed out at passers-by who filmed the attack rather than help him.

Four American Staffordshire terriers attacked the man, Mr Tat, as he went to move his car near his Drummond St flat, Carlton, on Tuesday night.

The dogs attacked him from behind and surrounded him, inflicting many bite wounds in a frenzied 15-minute attack.

Eventually, with the help of a nearby security guard, witnesses pulled the dogs off Mr Tat and called the police.

"He was very upset that there were so many people around and no one helped him," his son, Vi, told the Herald Sun.

"My father was very upset when he saw that they were taping the attack and not helping."

He said he could hear his father's screams from their 15th storey flat.

"It was so shocking to hear all the screaming and then hear my father was involved," Vi said.

"We want someone to come forward and take responsibility for this.

"We want the dogs found.

"My father is very big and tall. Imagine if it was a child the dogs went for."

Vi said his father feared the dogs could strike again.

Authorities have so far failed to find the animals.

The 52-year-old had an operation for his injuries, but doctors at the Royal Melbourne Hospital warn he has suffered nerve damage and may lose feeling in his right arm.

He had deep bite marks to his legs and stomach.
