A man has relived the horrific moment a pack of dogs mauled his horse during a peaceful beach ride south of Sydney.

Nathan Bourde was riding his horse Summer on a Wollongong beach when they came under attack.

The footage shows an unmuzzled dog, which Mr Bourde believes to be a pit bull, barking and running up to Summer before attacking her.

Mr Bourde tried to flee the area on his horse but more dogs followed him.

Mr Bourde, 36, was seen making desperate efforts to save the horse and himself from vicious dogs.

The female owner of the pit bull was heard shouting its name but she was unable to bring it under control.

'It was snapping at her legs, biting her stomach and chest. Then it bit my foot. It didn't have a leash, it wasn't muzzled and the owner was completely unable to restrain her dog,' Mr Bourde told Seven News.

Mr Bourde said he tried to kick the dog, who then attacked the horse in the face and bit a vein.

'It was like a tap, the way the blood was pouring from her face. She was bleeding to death... I ended up tying it up with a piece of string,' he said.

Mr Bourde somehow managed to control the attacking dog and took his horse to a vet.

Summer was given antibiotics and is recovering but Mr Bourde said had the dog been muzzled, all of this could have been avoided.

The NSW Government had last year increased dog attack fines from $550 to $1320 under the Companion Animals Act 1998 after more than 1,000 dog attacks were reported in the state.

American Staffordshire Terriers, Bull Terriers (Staffordshire), Australian Cattle Dog, German Shepherd and Rottweiler were responsible for most attack cases.

The law requires that American Pitbull Terrier or Pitbull Terrier can never be walked off its leash even in a designated off-leash park.
