Dr Katrina Warren looks incredibly youthful 20 years after starring on Harry’s Practice –  and you will never believe her age!

It’s been 20 years since Harry’s Practice finished it’s run on Seven, and since then, presenter Dr Katrina Warren has barely aged a day. 

The beloved pet expert stepped out at a Sydney park on Thursday with her trusty border collie Chilli looking as fresh-faced and youthful as she did in the early nineties. 

The petite brunette, 57, beamed as she joined a small group of volunteers and pet owners to speak about the mental health benefits of dog-driven exercise. 

Dr Katrina was a regular feature on Australian TV screens from 1997 to 2003 and her familiar face looks remarkably unchanged. 

She suited up for her day of advocacy in a pair of blue skinny jeans and an oversized ‘Mind’s Best Friend’ T-Shirt. 

She flaunted her glowing skin and broad smile as she extolled the virtues of regular exercise for a healthy life.

In research spearheaded by footwear company Asics, Katrina said that dogs are the ultimate movement motivators, with 65 per cent of owners saying their dog is their primary reason to exercise. 

Dog owners, Katrina said, are 31 per cent more likely to meet recommended physical activity guidelines and report better mental health as a result of daily movement. 

‘It’s hard to believe it’s been nearly 40 years since I first started out at vet school,’ Katrina gushed in a post last fortnight, as she shared a photo of her university graduation. 

‘YIKES! Here’s a throwback to me as a fourth-year vet student — complete with very enthusiastic eyebrows!’ she captioned the post. 

‘I’m still so proud to be part of a profession filled with people who lead with compassion, kindness, and an unwavering commitment to the wellbeing of animals. It’s not always an easy job.’ 

Journalist Jessica Rowe paid tribute to Katrina’s many years of service to the Australian public in the comments. 

‘Thank YOU for all you do to keep us well informed, educated & entertained about how to best care for our furry families!’ she wrote. 

With her border collie Toby by her side Katrina became a household Australian name in the ’90s and early noughties, advocating responsible pet ownership and championing animal welfare causes.

The famously happy border collie, who died in 2010, was the 57-year-old’s co-star on Seven’s long-running pet show Harry’s Practice. 

‘He was part of my identity,’ an emotional Katrina told Jessica on The Jess Rowe Big Talk Show in 2024. 

Admitting she still struggles with the loss of her loyal companion, she told listeners: ‘You just need to go through the grief.’

The vet added that it’s important to have people around who can offer support and sympathise.

‘Unfortunately we have this world of people who say things like “It’s just a cat it’s replaceable get another one”.’

‘Those sorts of comments make people just hide behind a door.’ 

‘All you can do to manage it is to keep yourself busy. One day the tears turn into smiles when you think of the memories.’

Dog owners, Katrina said, are 31 per cent more likely to meet recommended physical activity guidelines and report better mental health as a result of daily movement

Elsewhere in the chat, Jessica asked Katrina why she thought losing an animal is especially difficult. 

‘Grief is grief,’ Katrina said, adding that many people have confessed to her that losing a pet was harder than losing a family member.

‘They give you unconditional love, they don’t judge you and you can’t say about human relationships there’s always.

‘Your pets just warm your heart and so we mourn their loss because we are so used to having that joy…’

Katrina rose to fame on Channel 10 children’s program Totally Wild in 1994.

She later hosted Beverly Hills Vet in 2003 and Housecat Housecall in 2008 on Animal Planet in the U.S. 

Since her time on the hit lifestyle show, Katrina has built up a career as a pet influencer and educator and boasts 41,000 followers on Instagram.
