Professional Canine Trainer – Accredited (PCT-A) Dog Behavioural Trainer
Bachelor of Science degree
President of Association of Pet Dog Trainers 2012-present

Louise has over 32 years of experience with domestic and exotic species in both a training and husbandry/management capacity, from horses and dogs to tigers and meerkats. She worked as a veterinary nurse, dog/ cat groomer and animal attendant in a large busy vet practice in Sydney’s Eastern Suburbs for several years before moving to Taronga Zoo in 1994.

At Taronga, she works as the Unit Supervisor of Carnivores… that’s right, she’s a lion keeper! Her role is varied and covers duties such as carnivore husbandry and management, animal training and enrichment, diets and nutrition, staff training and supervision, media work, conference presentations and other forms of public speaking, research, education and conservation work.

Louise is the proud author of The Art of Introducing Dogs – a guide for conducting dog to dog introductions and regularly presents webinars, speaks on podcasts and at conferences nationally and internationally.

At home, Louise is guardian of Wynter the Shetland Sheepdog and Sekara the Siberian Husky (pictured with Louise, along with beloved Finley the Sheltie, now passed) – they compete in NoseWork, agility, obedience and rally-o.

Denise Bergin

Delta Accredited Instructor
Certificate IV in Companion Animal Services [Delta Institute]

Denise has worked for Positive Dogs since 2016 and teaches our Thursday Puppy Class at Enfield as well as Senior Puppy, Adolescent Dog, Building Skills, Advanced Skills and My Challenging Canine courses.

She has been a successful dog groomer since 2007 and through that role, Denise began to research how to best address dogs with handling issues — She learned that science-based, positive reinforcement training is very effective and lots of fun! This led to her becoming a professional dog trainer. 

For Denise, pictured here with her beloved Rufus, each day is an opportunity to spend time with dogs and work to make their grooming experience a positive one. Equally, each class or training session is an opportunity to educate and communicate with guardians and dogs alike using positive reinforcement.

Magda joined Positive Dogs in late 2019 and is currently studying the Certificate IV in Companion Animal Services. Her family consists of two dogs, a cat and a rabbit in their golden years with the exception of Floyd who is middle-aged and young at heart!

My pets have taught me so much about animal companionship and respect for their individuality. I’ve learned that using enrichment at home and outdoors through positive experiences and exploration is key to their emotional, physical and cognitive wellbeing.

I am fortunate to work with wonderful and professional Delta colleagues who believe in the highest welfare of animals by providing guidance and care through positive reinforcement and education.

Over the years, Magda (pictured with Trouble) has volunteered at dog rescue shelters across Sydney, wildlife sanctuaries abroad and she now volunteers as an instructor at Sydney All Breeds Dog Training Club.
