A man has pleaded guilty to six charges after his “unrestrained” dogs bit two men on the street outside his southwest Sydney home.

Tyson Fifita apologised today after his American Staffordshire Terriers, Kobar and Xander, both attacked a man outside his Fairmount Street, Lakemba address on January 30.

“It was dark, they both got up. No one screamed,” Mr Fifita told 9News.

“I feel bad for the victim, everyone involved.”

A passer-by tried to help the victim by rushing at the dogs with a council bin, then one of them turned on him.

“He was like straight forward on my stomach, I was very scared and I pushed the dog back and again he came back into my leg,” the victim, who does not want to be identified, told 9News.

Both victims were bitten and were hospitalised after the attack. (9news)

Both victims were hospitalised with their injuries.

At the time of the attack, Xander had already been declared a dangerous dog after biting a woman in Bankstown three months earlier.

Before that he was also reported for attacking a goat.

The dangerous dog declaration means Xander was required to be muzzled and on a leash in public.

According to police, the dogs were unrestrained when they bit the two men on the street. (9news)

While Mr Fifita insists both dogs were on leashes at the time, police records state the animals were “unrestrained”.

“If you don’t do those simple things and someone gets hurt, that’s on you and if a court finds you guilty they should throw the book at you and you should end up in jail,” Bankstown mayor Khal Asfour said.
