What happened to going to the pub? The doctors, civil servants and mechanics who spend their free time dressing up in rubber puppy suits while their 'trainers' lock them in cages and teach them tricks

• Australia's puppy play community has given an insight into their world
• Members dress in rubber dog suits and lock themselves into cages
• Some claim it is a sexual fetish, but members say it's a form of escapism
• Human pup trainers teaching them tricks during monthly meet-up
• Australian members work as doctors, public servants, and mechanics
• Believed to be 10,000 human pups across Europe, Asia, Australia and US

They say you can't teach an old dog new tricks, but the guy who trains grown men dressed in rubber puppy suits would probably beg to differ.

Members of Australia's underground puppy play community have lifted the veil on their secretive movement, which has 10,000 human pups across Europe, Asia, Australia and the US.

This week's episode of The Feed introduces Trainer PupBoss, also known as Jyan, who is a 'handler' for the doctors, public servants, mechanics and rail workers who lead double lives as dogs.

The men on the programme insist their desire to dress up as dogs is not sexual, but the movement has been banded by others as a BDSM fetish.

'It seems really simple because you're just getting on all fours and waddling around and going woof woof. But really it's so much more complicated,' said Trainer PupBoss.

He manages gatherings which involve locking the human pups in a cage and teaching them tricks on as they crawl around on all fours such as posture and presenting.

Human pups eat from doggy bowls and communicate exclusively through their own canine language during the gatherings.

GPup Alpha, who works as a doctor, explained has been involved in the human pup play community for over five years and defended accusations it is merely a fetish.

'Having the outlet of pup play gives me a recreation. We all have animalistic passions. As humans, we are sexual animals, and my animal just happens to be more German Shepard,' he explains

'For some people there's sexy time involved, but that's not the whole essence of it'

Seca, who spends his days working as a mechanic, said puppy play has become an addiction.

'I feel there is a hidden dog in me,' he said. 'I feel I have to live two lives in some ways.'

The Australian community is believed to include members from a mix of genders, sexualities, occupations and ethnicities.

It is difficult to determine how many members there are in Australia because they usually meet in private but it's believed there are monthly meet-ups in every state.
