After a successful career in the corporate world (attaining hard to get qualifications and people emailing wishing I would come back), I got back in touch with what really matters in life, and a big part of that was animals, especially dogs (and my kids).
I have also taught humans in communication at a tertiary level, and wondered why our communication with dogs seemed to be stunted in some way. (besides the whole different species thing :-b)
Having always had dogs, I attended classes, trained them and researched multiple training styles and techniques. However, I was still left with the feeling something was not quite right.
I was disheartened hearing stories of dog owners attending classes and getting the “dirty look” from the trainer because their dog was not a star student straight from the start. People often spend significant sums of money and go through multiple trainers and still don’t achieve the desired outcomes. Often being told there must be something WRONG with their dog, or even a straight to the face “It’s your fault as the owner”, even when the owner was trying to do the right thing – I thought “the industry needs to do better than this…
My previous experience was in Risk and QA – essentially “what could go wrong -and how can we address it? ” and “Is the job being done and being done right?” – while I did very well in these areas, my real strength lay in bringing harmony to teams and opening up the communication lines. Not to mention increasing efficiency.
So, Affinity Dog was born. A training solution for you and your pooch that is highly effective, long-lasting, and genuinely helpful. I wanted to create a practical and pragmatic training program based on evidence from the real world.
Affinity Dog is a place to get reliable real-world training, exercise from dog walking, and someone to look after an important family member when you go away.
I am a fully qualified Alpha Canine Professional Dog Trainer, having searched, found and practised these techniques that don’t rely on treats, and are solid under distraction, and I’d love to share them with you.

EXCELLENT Based on 26 reviews Vee Gordon2024-08-08Trustindex verifies that the original source of the review is Google. Christian is such a knowledgeable trainer and takes the time to explain certain techniques and equipment to use and why. I'd highly recommend him to anyone looking to invest in their dog Kharishma DSouza2024-05-24Trustindex verifies that the original source of the review is Google. I highly recommend Christian for training our dog. We are new dog owners to a 2 year old Sharpei Cross Terrier we bought from a shelter nearby. We had lots of behaviours such as pulling on the lead, fear and panic to people and dogs on walks, constant jumping, play biting and unable to stay by our side without pulling on clothing or nipping our ankles. We kept her in the backyard most of the time as she couldn't be controlled in the house. We recently completed the foundation course and we have seen our dog become a wonderful companion to us and our kids in just a few weeks. She walks well, can sit beside us and really has learnt to trust us. Her fears on walks have significantly reduced. She is now able to be a part of our family indoors and we have well behaved and happy dog. Christian is very experienced and shares his knowledge and breaks down the training techniques into simple steps that you can follow. I found him really easy to talk to and he is happy to answer questions. I found the whole experience really helpful and would highly recommend him. Olivia Campbell2024-04-24Trustindex verifies that the original source of the review is Google. We recently completed private training sessions with Christian for our 1-year old staffordshire bull terrier. We were struggling a lot with our staffy pulling terribly on the lead, being overly excitable, not listening to us outside of the house and jumping up on us and other people. After trying other trainers with no success, we contacted Christian. Over the 6-weeks of private sessions, we have seen an amazing improvement in our staffy's behaviour - which we previously thought was not possible! He is now able to sit/drop/walk in high distraction areas, settle inside the house on his bed and is able to walk nicely on a loose leash. Christian is a fantastic teacher to both dog & owner, through demonstrating and supporting to achieve the desired outcome. Not only does he show the training technique, but explains the thought process behind the dogs actions which was very helpful in understanding what was going on and why. Christian provides a clear and concise training model which we will continue to adopt in our everyday life. I highly recommend Christian to any owner struggling with an undesirable behaviour, we now have the knowledge/training techniques to best handle our dog. It has had a very positive impact on our relationship with our dog as well! :) Baelal Shaukat2024-03-16Trustindex verifies that the original source of the review is Google. Best dog trainers and very kind people Cheryleen Maano2024-02-15Trustindex verifies that the original source of the review is Google. I would highly recommend Christian. He trained our 4 year old Pomeranian for 2 weeks and now he is able to sit, drop on command whilst walking. When cars drive by and families walk past him he no longer barks or spins. We can to take our dog now for walks peacefully which we are so happy about! Thank you for your amazing service Christian 10/10. Di Harb2023-09-15Trustindex verifies that the original source of the review is Google. Christian is worth his weight in gold. My dog has just come home after the 10 day program and for anyone contemplating the program because they feel it's a lot of money, it is worth every cent and more! The difference in my boy is amazing and with some consistency from us I know my boy will continue to grow. We can't thank you enough Christian! Reuben Korngold2023-06-23Trustindex verifies that the original source of the review is Google. We had a challenge with a boisterous 30kg 1 year old standard poodle that wasn't listening, staying, and constantly pulled on the lead. When our dog returned, his behaviour was completely different. He listens, stays, and walks very nicely and is able to be the part of the family that we wished for. If you are reading this review, you have found the right place to get the results you need. Bridie Hutchens2023-06-10Trustindex verifies that the original source of the review is Google. We recently placed our 9 month old female GSP, Vivi with Christian for the 21 day program. Despite being experienced GSP owners, we were truly at the end of our tether. We were unsure how to help her or ourselves. She wasn’t growing out of the chewing stage, jumping on us and everyone else, digging trenches in the backyard and despite multiple walks or park sessions per day, we were not providing adequate stimulation. At a loss, I contacted Christian who was very reassuring and gave me a full overview of the training and answered all my questions. Christian mastered fundamental training with Vivi. Her jumping has almost subsided completely. She sits and drops with distractions around her. The training session at pick up time was so good and we have continued building from there. It’s had a positive impact on our lives! The cost is big but well worth it for the outcome! Katrina2023-03-04Trustindex verifies that the original source of the review is Google. TL;DR: Worth it, best trainer in Sydney. I sent my dog Luna to board and train for 10 days with Christian in February 2023. He sent through regular updates throughout the stay and at the end he had a training session with us in our home. I was initially very nervous to have Luna stay at a board and train, as I had heard terribly things about boarding places, especially the high rated big ones in Sydney. But I made the right decision because I could tell Luna was happy and was treated very well. She came back miles and miles better than where she was before the board and train. She is a schnauzer with significant barking problems, and she came back more behaved, but also a calmer, happier dog. Even though I initially found the cost expensive, especially in this economy, it was worth every cent and probably more. In the end, this has saved me money - there are many trainers that charge hundreds or thousands and will spend a couple of hours with you and your dog. Without the constant attention during a board and train, it would have taken months or a whole year. Christian is also probably the nicest trainer I have met. I find that many are very condescending or judgey towards owners, but Christian was the opposite. He was also open to my million questions, which I appreciated. I have recommended him to everyone I know, and will be sending my other dog for board and train when we are able to.
