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.

I can’t recommend Ali enough! I’ve had my dog Milo for a little over a year, and from the very beginning, it was a struggle. Milo wouldn’t listen, destroyed things, and was hard to manage on walks because of leash pulling. He would also bark or nip at people, and I even found myself taking the back way in our apartment to avoid people because I knew he would react. I honestly didn’t know if I could handle him sometimes and contemplated giving him away. Working with Ali has completely changed everything. Milo listens, is calmer, and now I can confidently walk past other dogs and people without being fearful of him barking or reacting. I can even have company over without worrying about him barking until they leave or jumping all over them. I finally feel confident taking Milo out, around people, and leaving him alone. Ali really cares, is so patient, and goes above and beyond. If you’ve been thinking about getting your dog trained, this is your sign!!!
