FOOTAGE of a dog attacking two horses on Nudgee Beach has emerged on social media.

The footage shows Keesha Moignard and her 19-year-old daughter Lucie trying to keep hold of their two horses as a large black dog runs towards them and attacks.

Onlookers gasped during the incident last Saturday morning while others took photos and videos of the attack, which brought one horse to its knees.

Ms Moignard claims she was also bitten on the knee during the chaos.

The video has had more than 107,000 Facebook views and 1100 shares.

Ms Moignard said the horses sustained multiple cuts and bite marks which were confirmed by a veterinary report to be “consistent with a very aggressive dog attack”.

One horse was also bitten on the neck, just centimetres from a major artery.

A Brisbane City Council spokeswoman said it was currently investigating an incident involving two horses and a dog at Nudgee Beach last weekend.

She urged residents with any information that might assist the investigation to contact the council on 3403 8888.
