President - Sarah Campbell

Happy Tails Training Tasmania

After growing up on a farm surrounded by dogs, Sarah has always been on the path of dog training in one way or another.

However, it was her Labrador cross called Seamus and his fear towards other dogs and small humans that lead Sarah towards learning more about dog behaviour and started her down path to become a dog trainer.

After completing a Certificate IV in Companion Animal Services, she started Happy Tails Dog Training with a fellow positive trainer (Moire). She offers Puppy Preschool, Group Classes as well as a number of specialised classes such as Out and About Sessions and Adventure Courses and private consultations. 

She lives with her Red Heeler x Maxi and Border Collie Jack. Jack is fully deaf and the training journey with him has been a unique but rewarding process. 

Her aim as a dog trainer is to help dog owners form better bonds with their canine companions by giving owners the skills and knowledge they need and inspiring them to teach new behaviours, stimulate their dogs mind and enrich their dogs every day lives in a variety of ways.

Mandy Hedderwick, Secretary

Praise the Dog Canine Services

Mandy is based in Adelaide, South Australia, where she runs her dog training business, Praise the Dog Canine Services.

Mandy was born and raised in South Africa and grew up with both working and family dogs. Mandy moved to New Zealand in 2003 where she studied and worked in academia. Her love for science and enquiry grew in the years she researched and worked at Otago University in Dunedin. While in New Zealand, Mandy volunteered in Dog Rescue for 7 years where she received practical dog training education and experience, and discovered an aptitude for helping dogs through trauma. After moving to Australia in 2013, Mandy worked as General Manager of the Adelaide Lightning WNBL team, and Chief Operations Officer of the Adelaide 36ers and Adelaide Arena. An opportunity to get back into science proved too good to pass up, and she moved into the Biomedical Engineering field. As she got more involved in dog sports with her own dogs, and experienced changes in her personal life, she took the inevitable leap into the dog services industry and started her own dog training business in 2021.

In addition to running her own dog training business, Mandy teaches dog training and handling, and Principles of Animal Behaviour and Welfare at The University of Adelaide's School of Animal and Veterinary Sciences. 

She is the guardian of 2 Clumber Spaniels, Belle and Rafferty, and a Border Collie, Leo. Mandy adopted Leo when he was 15 months old, and he became her greatest teacher. While working through Leo’s anxiety, reactivity, and repetitive behaviours, they developed an incredible bond which fuelled Mandy’s passion and resolve to help other dogs and their people live better together using fear free/force free training methods.
