Footage from a pet camera first captured an amusing scene as two of the homeowner’s dogs nosed open a sliding door, leaving it slightly ajar as they headed outside.

What happened next was unexpected—a large white bull appeared at the entrance, cautiously poking its head through before deciding to enter the room entirely.

Following the bull’s lead, a horse trotted into the space, joining the bull in a curious exploration of what seemed to be a living room.

The camera also spotted another horse lingering near the door outside, though it remains uncertain if this horse joined the indoor adventure.

Mackay, who shared the amusing incident on his official Facebook page, found humor in the situation despite the potential hazards posed by a bull roaming through his home.

“Note to self: The dogs can’t be trusted with door security…” the post read.

“Dinner finished early last night when I decided to check the pet cam to find Thunder figured out how to nuzzle open the door.”

The end of the video taken later that night shows Mackay surveying the mess the animals made, with one of his dogs beside him.

He said there was no major damage and that all animals in the video were unharmed, but he still had some concerns they may return.

“Now the outside animals know what aircon feels like and will no doubt try again,” he said with a hint of humour.
