i had taken my dog Wrigley to 8 or 9 different trainers for her reactivity and nothing worked. While we love our dog and she was good at home, she couldn’t go anywhere without barking. Not sure what inside me decided to try another trainer, but I did. I’m so so glad I found Ali. His training methods actually work and he trains you the human as well on what to do. That I believe is what makes a difference the most. And his training actually works. While Wrigley is not at 100% yet, she is better with her reactivity then she has ever been and we are positive about the future.

Working with Ali at 410K9 Dog Training has been life-changing for our family and our dog, Bailey. Bailey is a six-year-old dachshund who struggled with severe reactivity and had an extensive bite history. He would go after guests in our home, which made everyday life stressful and unpredictable. Before finding Ali, we worked with three different trainers and invested a lot of time and effort, but unfortunately, we didn’t see real results. Everything changed when we started training with Ali. He was able to clearly identify the issues and implement a structured, effective approach that actually worked. Now, we can have people over without worrying about Bailey trying to run up and bite them. Bailey understands and holds his place command, and the overall environment in our home feels calm and under control. We’re really looking forward to continuing with pack walks and possibly doing more training in the spring. We’ve been extremely pleased with our experience and the results we’ve seen. We highly recommend 410 K9 Dog Training and Ali to anyone dealing with behavioral challenges in their dog. — Carol Kaufmann & Dick

We can now go on walks stress free! Very reactive dog now can pass another dog and not react. It's been a great experience for Scooter and me.

Ali Hamza is the rockstar of dog training. I have felt so supported and cared for in a professional way in working with him. I have 2 yellow labs, both female and alpha. We dealt with pulling issues, weight issues, Mom training issues (me). We are not done since I signed us up for a second round of this. Annie is 12 and Beast( nickname ) is 6. Annie is a retired service dog who likes to sniff. Beast is just not trained-my fault. We have lost weight, trained with prong collars, spent time together and I am proud to say that Beast is no longer beast like. Her real name is Billie Jane….and true story from tonight. Bj would always pull to get to play with other dogs, pulling me down and having to let go of leash. Tonight, she took leash correction from me walking both dogs together and completely ignored the other dog….,huge win! This is the dog walker being able to walk both of them. And a pic of each of them. Last story- Beast learned place command in one session. She stayed put the entire time and wagged her tail for nearly an hour….She loves to learn and gets it quickly. Ali Hamza has given this gift to us!

He got my dog disciplined as a young pup and it has stuck with him as he’s grown. Very attentive and will help with any issues you tell him. Very caring for his clients and his k9’s.

Training with Ali at 410K9 has been a game changer, especially when it comes to protection work. The foundation of obedience we built has made my dog far more confident, clear-headed, and controllable — which is exactly what you want in a real protection dog. My dog Ghost, an XL Bully, now looks to me before making decisions, shows strong impulse control, and stays calm and neutral in everyday situations. That level of control and structure has directly translated into better protection work. He understands when to be calm and when to switch on, which makes his protection training safer, clearer, and more effective. Having a clear activation word has given me real peace of mind. Ghost knows when he’s working and when he’s not, and that clarity has made him a more stable, reliable protection dog — not just reactive or chaotic. Because of the structure and obedience, I can take him more places, including family members’ homes and dog-friendly public spaces, without issues. The training didn’t just build a protection dog — it built a balanced one. If you’re serious about protection training and understand that obedience and control come first, I highly recommend Ali and 410K9.
