EXCELLENTTrustindex verifies that the original source of the review is Google. All in all, I found her a true teacher who genuinely loves her job the most. One of the first things that impressed me was her use of Lyka treats (a clear sign of quality and care, especially when so many other trainers rely on cheap, low-quality options.) What really sets her apart is how she supports every training technique with research-backed reasoning. She doesn’t just tell you what to do; she explains why it works, referencing the latest studies and showing she’s always up to date with the most effective methods and best practices. She also managed to gently correct the damage left by a previous would-be “trainer” who had left our puppy quite anxious and traumatized. Her patience, knowledge, and calm energy helped rebuild our puppy’s confidence. Another thing I love is that she’s never watching the clock. Even though sessions are scheduled for two hours, she stays way longer if you still have questions or need extra practice—something truly rare these days. Finally, she strikes the perfect balance between theory and practice. She first explains the reasoning behind each technique and then shows you how it works in real life with your dog. It’s an incredibly effective and eye-opening approach.Posted onTrustindex verifies that the original source of the review is Google. Liarne has helped me so much in training of Yoshi. She is clearly very competent in her approach, and her years of experience is clearly displayed. I cannot recommend her enough to anyone looking to create the perfect dog.Posted onTrustindex verifies that the original source of the review is Google. I am pleased to be able to provide such positive feedback about Liarne and K9 Trainer. I have had for almost two months a beautiful, pure-hearted, eager-to-please five year old poodle called Poppy. While we have made some progress, there have been a couple of intractable problems in Poppy transitioning from a semi-rural life to inner-city apartment living. The people, the dogs, the traffic and building noise have been a lot for her. Poppy has, in particular, been fearful of other dogs and people, so much so that when friends visit she visibly shakes, growls defensively, hides behind me and barks. Liarne came for a home training session on Friday. On Sunday, I had a friend over for lunch. We both followed Liarne’s instructions to the letter. The results were perfect - like a magic trick. Poppy was, in no time at all, happy and calm and had made a new human friend. She even saw my friend off - on her own - at the lift. Liarne’s techniques have also helped stop Poppy jumping up for attention and being a darting trip hazard. We still have progress to make but in just a couple of days, the results have been excellent. So far, I have a happier, calmer dog and I am a more confident owner. Thank you Liarne.Posted onTrustindex verifies that the original source of the review is Google. Liarne has truly set us up for success. With our new puppy “Buddy” things seemed a little overwhelming when it came to training. Knowing that a poor approach now could lead to devastating repercussions later in life, Liarne has given us the insight into a doggies psyche and provided the best path forward for a long life of happiness together. Liarne was very professional and we couldn’t recommended her more. If you want your Doggy relationship to succeed, call Liarne. 🤩🤩🤩🤩🤩Posted onTrustindex verifies that the original source of the review is Google. Liarne was fantastic. So many helpful & easy to implement tips. I feel confident I now have a great blue print to take us forward optimally. Thank you Liarne!!!!! 🌟🌟🌟🌟🌟Posted onTrustindex verifies that the original source of the review is Google. If you get a dog PLEASE see Liarne. Our dog couldn’t stop barking, always scared, nipping constantly. Even though she’s a puppy, Liarne gave us more insight and understanding of our puppy’s psychology. We had already been to a different puppy school, but this was entirely different and much more effective for our puppy’s behavioral changes that were and are absolutely necessary. Her approach is refreshing and really takes a more psychological approach to training which we’d never had before. We are so happy with this training experience!!Posted onTrustindex verifies that the original source of the review is Google. Liarne is a true professional and is exceptional at what she does. My 3 month old Pomeranian Pepe just completed Puppy School, and it was truly the greatest experience. Pepe has learned so much and importantly, had the opportunity to socialise with other puppies in a safe and controlled manner. As a first time puppy owner, the information and support that Liarne provided to me was invaluable. Liarne is masterful and so passionate about what she does, and her level of connection to her work shines through. I could not recommend Liarne more highly.Posted onTrustindex verifies that the original source of the review is Google. I would highly recommend Liarne as a top dog behavioural specialist and trainer. We recently got a new cavoodle puppy and live in an apartment with a courtyard. Our puppy was initially challenging and we found it so stressful as we had no idea to train her and to make our life easier. Liarne came to our home and did an intensive 2 hour session to teach us the puppy essentials. This was transformational and now we are continuing to follow her teaching and rules and our little puppy is being much more compliant. Before our training I was using articles from other trainers about redirecting biting but Liarne taught us techniques which are derived from dog behaviour. She’s a top dog trainer and you can definitely rely on her to help you have the best start and long term relationship with your dog. As our vet said, dogs aren’t euthanised for illness, it’s mainly for poor behaviour. Thanks Liarne 😊Posted onTrustindex verifies that the original source of the review is Google. Liarne came to us because we have a 7 month old that has started crawling and our standard schnauzer was starting to growl at her as she passed. Liarne came to our house and immediately began to offer her recommendations on the situation. She is friendly, professional and is highly knowledgeable of the behaviour of dogs. We have already noticed a change and it’s been a week since she came. Liarne has remained in contact with us and provided us with documents to refer to. I couldn’t recommend her higher. This has made our dog so much happier and created a safe environment for our baby.

Frequently asked questions.
Teaching your dog healthy habits, cues, and manners is essential at any age. Dog training involves so much more than just telling your dog to sit and stay.
We use positive, reward-based training to encourage and maintain good behaviour. This also allows us to address complex behavioural issues such as aggression and separation anxiety, which can be especially common in rescue dogs.
We don’t just train puppies, either. Contrary to the popular saying, you can teach an old dog new tricks! Whether you want to change old habits or teach them some new ones, you can train your dog at any age.
At K9 Trainer, we use a positive reinforcement and reward-based method to get you lasting results. Punishing a dog, shouting at a dog, or scolding a dog are all things we are strictly against, and we never use these in our dog training. Not only does punishment not teach your dog what to do and not do, but it also creates a sense of fear in your dog that will only make matters worse.
Our dog training method was developed using research on dog behavioural psychology. This means we focus on the way dogs think, learn and process their environment. By observing and analysing the relationship you have with your dog, as well as the environment they’re in, we can quickly identify the root cause of the issue and reshape your dog’s behaviour for good.
You can check out our testimonials and Google reviews to see just how well this methodology works for every kind of behavioural issue or concern.
Yes! We offer group sessions at our popular puppy school classes in Sydney. These are perfect for training and socialising puppies, preparing them for life in the big, wide world.
Our private dog training sessions are for dogs of any age. Conducted in the privacy and comfort of your own home, this is the best option if you want personalised 1:1 training tailored to your dog’s specific needs and concerns.
We often have clients from our puppy schools book in for a private dog training session after they finish the 4-week puppy training course, as they want to reinforce all of the essential obedience training they learned in puppy school and ensure their dog learns all the right things from a young age.
Private in-home dog training is also great for addressing concerns as they arise, like if you notice your dog developing problematic habits or tendencies (anything from growling to barking, nipping and biting, digging, whimpering, chewing, jumping, chasing other dogs, resource guarding, separation anxiety and more).
You’ll find that dog training prices, including puppy school and private dog training prices, vary greatly across Sydney. Some dog trainers might only offer online training; some dog trainers might space out the training across multiple private sessions and charge you for each visit.
At K9 Trainer, you can visit us at our in-person puppy school classes in Sydney. We will travel to you for private in-home dog training. You also have the option of online dog training conducted over video call, which is popular with clients who live interstate or overseas. You can talk to us today to enquire about pricing and see which option would work best for your dog and your schedule.
Puppy school is for puppies that are 8–16 weeks old.
If your puppy is over 16 weeks old, don’t despair! It’s not too late for training; in fact, this is a critical time in your puppy’s life when you’ll want to teach them all the right habits and behaviours to help them grow into the best dog they can be. Learn more about our private in-home dog training, or talk to us today.
Yes. Separation anxiety is a very common yet complex and misunderstood behavioural issue in puppies and adult dogs. What works wonders for one dog might do nothing for another dog.
Our Head Trainer Liarne Henry has over 30 years’ experience specialising in behavioural dog training. Liarne’s methods are based on the latest research and a deep understanding of dog psychology, incorporating proven techniques into her personalised training programs for dogs with separation anxiety.
