But on August 1, all horses will be wearing an imaginary party hat, as they celebrate their birthday.

In Australia, all thoroughbred horses celebrate their birthdays on August 1, to allow for the standardisation in horse events, like racing, to link up with the breeding cycle of the animals.

It makes it easier to keep track of bloodlines and makes it easier in the racing industry to keep track of the horses' ages.

Glengarry horse owner Liana Seadon said she had grown up always wanting to own a horse.

"It took me a while but I saved up all of my pocket money until I had enough money to buy one," she said.

Fast-forward to the present and Ms Seadon has four horses, a warmblood, two thoroughbreds and an Arab cross, and competes in showjumping events.

She said all of her horses had different personalities.

"Some of them are smoochers, but others not so much," she said.

"The thoroughbreds are ex-racehorses and they are just so chill, they are used to so much happening at the track that when they get to a paddock nothing phases them much.

"But the Arab cross, he's quite cunning, he's more conniving, more likely to give you a nip as you go past with food."

Ms Seadon said being a horse owner came with it a host of responsibilities but it was very rewarding. She said she wasn't planning a party for her horses but they might get an extra carrot.

"It's definitely not for the faint-hearted, it means lots of early mornings and late nights, with feeding and rugs and things but I just love the bond you get with these big animals," she said.

An adrenalin rush of being partnered with an animal of this size was something Ms Seadon cherished and she loved sharing her horses with her son, Tom.

"He loves to feed them and brush them, it's one of his favourite things to do," she said.

While Tom, 3, hasn't yet shown an interest in riding, Ms Seadon said showjumping was a family-friendly sport, and she was happy teaching him the basics of being safe around horses.
