An out-of-control dog has been filmed viciously attacking a horse in front of people at a busy park.
The footage, filmed in Centennial Park, Sydney, Australia, showed a horse and its handler walking around a dedicated horse track on Saturday, July 30 - moments before the incident occurred.
A large white pit bull is then filmed circling the large animal before making several attempts to launch itself at it, reported the Daily Star.
The dog - which wasn't restrained by a leash - ran around the horse, as shocked onlookers unsuccessfully tried to grab the pet.

Meanwhile, the horse was filmed galloping in circles in an attempt to avoid the dog - narrowly avoiding trampling it before trying to kick it.
The woman who recorded the clip was heard yelling: “F*****g hell. Oh my god" as the incident continued to escalate.
Eventually, the dog was captured by its owner, who managed to clasp it by the collar before exiting the park.
Posting the clip to Facebook, the witness wrote: "A pit bull off-lead with two owners unable to control it as it was intent on attacking the horse. After the incident the two owners walked off with no apology or details, and got into a car."

Meanwhile last month, a devastated gran recalled the moment her daughter was savaged to death by her pet dog which she believed “turned mad in the extreme heat” and warned the public to watch out for the pets.
Mum-of-two Joanne Robinson, 43, was understood to have been pinned down by the jaws of her Bully XL called Rocco, after being seized around the throat inside her home after a night out visiting a pal.
And earlier this year, a 22-year-old dogsitter suffered severe injuries after being bitten 800 times in a horrific dog attack.
Following the attack, Jacqueline Durand left in a medically-induced coma and had skin hanging from her face.
