TJ trained my four dogs, two pit bulls 4 years old and two frenchies 2years old. They all have different personalities , boy pitty was so anxious, not good with other dogs, scared of thunder and TJ spent hours with him during thunder storms and got him comfortable with other animals, not just dogs. My sweet boy is so perfect, able to self soothe and make good choices I can take him anywhere!! Girl pitty was stubborn and lazy, and totally opposite of boy pitty, TJ was able to clean up her lazy attitude and get her motivated! I had one naughty frenchie who thought he ruled the roost, and now he is the most disciplined of them all, so obedient and amazing!! The other frenchie was stubborn, couldn’t cut his nails without a full on attack, the first time back at the groomer the first thing she said was “I am so impressed, they were good before but wow, I would like to know the technique the trainer used because I cut his nails without any issues” I am from out of state and I got constant updates, text, video, email from TJ. Any time I reached out I got same day responses, not to mention the reintegration time with the dogs, hands on training for me and my family and all the equipment to continue training. To top it off hand made collars and leashes too!!!
Worth the time, absolutely worth the investment to be confident taking my dogs anywhere! I have the perfect pack and TJ taught me how to be the pack leader, and give my dogs the best life possible!! Thank you TJ !!
We have a crazy energy, high anxiety, 3-year old rescue, Luna, who is fearful of all things. TJ has been a blessing. He has taught us how to overcome her quirks and work with her to overcome her fears and anxiety. Through persistence and love, Luna has overcome many things. We are so thankful for everything TJ has done for Luna, and they have developed a wonderful bond, something that does not readily happen with Luna and just anyone. People continually comment what a "night and day difference" working with TJ has had on Luna, and we are so excited to continue to see what she is able to achieve next! Thank you, TJ!

Every aspect of our facility is designed to reinforce what your dog learns, ensuring they are prepared for the real world once they return home.

In February, my dad passed away and I had to make a tough decision, take on his 3-year-old Mastiff mix (Smoky). The dog needed training and direction after three years of no structure, so I decided to send him to the 4-week training program. TJ was incredible the whole time, providing updates, videos, instructions, and moral support. Not only did TJ help Smoky with the difficult transition after losing his person he helped me just as much. TJ is unmatched and I cannot imagine a person you can trust more with your dog’s wellbeing and safety. Thank you TJ, for helping both Smoky and myself make it through this challenging time.

TJ took our 2 rescue dogs that had some training to the next level. The dogs are happier as they now have a routine and are more confident. It has made us all a better happier family. Recommend him with 10 stars as I was at a loss as to what to do.
Thomas and his team took such great care of my Josie! While the training was all wonderful, and his video demonstrations have been so helpful, my favorite thing has been Thomas’ willingness to share his time and expertise as I ask a million questions along the way. He really takes the time to make sure you feel confident and equipped to continue the work he starts with your pup. Highly recommend him and his team for your dog’s training and care!
"TLDR: I could not recommend TJ and zrodfx K9 enough. I waited a month after training to post a review so that I had time to really evaluate the differences in my sweet guy and I can assure you that the things I learn about him just keep getting better. His obedience is rock solid, his behavior around other dogs has improved as a result, and he is genuinely excited to train and learn new things. TJ has also answered my endless questions post-training and is truly invested in Gideon's future, making him a training partner for life. If you want a dog who not only listens to you but is excited to be doing it, send him to TJ.

I sought out training for my 3.5 year old Mini American Shepherd after a year and a half of trying to manage what I perceived to be anxiety and reactivity. I have been training Gideon since he was 8 weeks old and have done a lot of obedience training, but he still developed his own issues over time. I tried taking him to another trainer a year ago who charged me $400 for an hour of forcing Gideon into a dog park, slapping an e-collar on him, and then over-correcting him for reacting, making him afraid of the e-collar. The main point of sending him to a board and train was for his own quality of life--all I want is for him to be happy and healthy (and live forever)."
TJ has done wonders for our dog! Odie is almost 7 and doesn’t get along well with other dogs so trying to walk him was a nightmare. In just 3 weeks training with TJ he walks next to me like an angel and is all around better behaved. TJ is so patient and always willing to take extra time to answer any questions I have or show me how to enforce some of his training. So thankful we found him!
What I’ve experienced Zrodfx K9 do with our dog, Dude, is unbelievable. Before, we had a dog that wouldn’t listen to even our most basic commands and seemed constantly anxious. We decided to get professional help when he started yanking HARD at bikers passing by.

Now, our Dude can follow commands and be “place” comfortably for hours on end. His anxiety has melted and, probably most importantly, we’ve learned how to be better leaders for him.

Highly recommend!
TJ revolutionized our communication with our pup, Tucker! He extensively worked with him during the board and train program and consistently sent update videos so we knew how the training was going and would have resources to look back on once Tucker came back home. TJ won our shiba (and us) over and continues to be a wonderful resource for us when questions arise. Our family highly recommends TJ to anyone who’s looking for a trainer for their pup!

TJ is a miracle worker and a true dog whisperer! My wife can finally walk our Rhodesian Ridgeback without being dragged around. Duke loved his training and is excited to have a new purpose with his continued success. I thought Duke would never look at me again, but he thoroughly enjoyed his time with TJ and is such a mature, responsible dog now. Highly recommend!

I cannot say enough great things about our experience with TJ and Zrodx K9 Dog Training. It has been absolutely life changing for our whole family. Our pup (Barkley) has the tools and confidence to be out in public and not be anxious and also crate trained at home. We are forever grateful for the love and patience TJ showed and often go back to videos. I highly recommend anyone of any breed work with him on having the best relationship with their dog.Toby, Jen and Smoky
Absolutely outstanding training service. I was on the verge of having to re-home my pup until I went through this program with TJ. Extremely knowledgeable, my dog is like a completely different dog and I could not be happier to keep my boy and be able to do so much with him now. Even his groomer is impressed! Highly recommend for anyone.
TJ at ZRodFx is a K9 trainer in a league of his own! He is patient, thorough, and deeply invested in training pups to live their very best, happiest, and most enjoyable lives. TJ worked with my Dutch Shepherd and solved every challenge that we were facing…he saved my pup! I highly recommend TJ and cannot speak highly enough about how great his training and care the provides to the K9’s he works with. Five+Stars!!

"TJ is absolutely fantastic! He had our 2 year old Pit/Lab mix Rosie for about a month board and train, and before she arrived she was super excitable, energetic and had a hard time settling down. We were also super worried about her general reactivity and how she would respond in the presence of other dogs and animals. After the time with TJ, she’s come back a different dog! She had a great time on the ranch and she is now fully trained in obedience as TJ discovered how much she loves working. He was also able to help us learn that she just didn’t know how to behave in the presence of other animals and now, using the foundation that he laid with her, we’ve been able to adopt a lot of those learnings into our life back at home. We’re super appreciative of the time Rosie spent with TJ and are looking forward to continuing to implement his methods. We would absolutely recommend for anyone looking for help with their fur babies and we’ll also definitely come back for refresher time in the future!"

TJ exceeded my expectations in every way. I had my doubts going in due to the nature of my pup’s behavioral issues as a stray, but wow I could not have asked for a better experience. Not only does Simba walk on the treadmill daily, he also takes himself upstairs for naps and no longer exhibits defensive behavior on walks. Anyone who meets Simba asks how I trained him so well and I have to give TJ the credit! His passion for dogs is evident and he invests so much time and energy into training. In fact, he offers a lifetime guarantee! Beyond grateful to have found Zrodfx K9.
Wow, we couldn’t be happier for taking our puppy to TJ. Here we are a year later and she’s just the best, most well behaved and adjusted dog ever. We opted for four weeks of board and train and it was worth every penny. Since then, we’ve had no fewer than three friends put their dogs through his program as well, all with great results. The amount of attention and genuine care he gives his dogs is unparalleled.
Sending my dog to TJ for a board-and-train was the best decision. As a first time pet owner, I really didn’t know where to start with training. I researched other training programs that were less of a commitment, but chose to do the board and train as I wanted a strong foundation. It’s been over a year since, and her training has stuck, making my life as a dog owner so easy! TJ is SO knowledgeable and passionate about every dog. His facility is clean, professional, and the limited number of dogs he takes at a time are well taken care of. 

This was probably the best decision I have made. I had a dog who would not listen and could not train and another dog who was so anxious about everything. He would not get close to another human without trying to bark or run off. Walking with these two was nearly impossible. I avoided it until i decided to sigh them up for training. Now we go on walks 3 times a day and I actually enjoy walking them. People come over to my house and it is less stressful. The amount of care he showed them was unbelievable. You can truly see how much he loves dogs and wants every dog to succeed. My sharpei is allergic to everything and he took so well care of her and was so concerned about her. He actually introduced us to a cream that has made her life so much better. If I would ever get another dog I would send him here to get trained right away. My dogs were so anxious going and were so comfortable with him by the end! Truly blessed that we found him he has changed our lives for the better. Thank you so much !
