The disgusting moment a man decided to use a drinking fountain to wash his dog's bottom has been caught on camera.

Rebecca Laurie caught the man washing his dog at the popular drinking spot at Rushcutters Bay Park in Sydney's east.

The young mother was enjoying a morning with her family when realised what the man was doing and was horrified.

Video footage Ms Laurie captured shows the man putting his dog's bottom straight into the drinking fountain and cleaning it.

The man can be seen lifting the dog's tail and rubbing dirt off with his hand - allowing it to fall onto the bubbler.

Ms Laurie told The Daily Telegraph that her daughter - and many others - love the bubbler and often use it during their days at the park.

'It is completely disgusting, not to mention a health risk, I am sure people who (haven't seen the video) are using that bubbler today,' she said.

Many who saw the man's actions were disgusted by the confronting sight and tried to make the man stop by calling him out.

However, Ms Laurie said the man went on with his actions unfazed and continued to clean the dog.

'Six or so people including myself told him, he did not care in the slightest and actually made the comment that we don't drink from the bowl of the bubbler,' the young mother said.

The video has since sparked outrage from those who frequent the park.

Many people commented on how 'disgusting' it was - especially in broad daylight on a busy Saturday.

'I will never drink from a bubbler again,' one woman wrote on Facebook.

'It's completely disrespectful,' another man commented.
