dog trainer Sean O’Shea

I was about to return my dog when I met Sean. I gave him a week to “fix” 4 things: Come when I call; Get along with cats; Separation anxiety; Housetraining. He accomplished it all in 5 days. The best.– Robert L.

Founder/Head Trainer

Hi everybody, my name is Sean O’Shea, founder and owner of The Good Dog Training and Rehabilitation. I founded The Good Dog with one goal: Providing dog owners with the help, answers, and results they desperately needed, along with the care, compassion, and understanding they deserve. As someone who started many years ago with two dogs with serious issues, I know firsthand what it’s like to feel frustrated and hopeless. The good news is, there is hope! My team and I have worked tirelessly to devise a program that offers the very best answers and solutions to even the most challenging K9 issues, which has enabled us to regularly perform “miracles” with dogs that other trainers have given up on, or are unwilling to work with. Our mission and our commitment is to create amazingly balanced, well behaved dogs, and happy, highly satisfied owners. So if you are ready to transform your dog, and your life, we are ready to help.

*Sean is internationally-recognized as the leading LA dog trainer and dog behavior expert, specializing in aggressive dog training. In 2013, Sean was personally hired by Cesar Millan (The “Dog Whisperer”) to teach and train students alongside Cesar for his highly-acclaimed seminar Training Cesar’s Way in Santa Clarita, California.

He’s a regular guest on Jeff Gellman’s widely-heard and highly rated dog training radio show “What Would Jeff Do?”, and authors the popular blog The Good Dog Life Blog. He trains rescue/shelter workers how to more successfully rehab shelter dogs, and travels the U.S. training other dog trainers who are eager to learn his unique approach, techniques, and philosophy, through his and Jeff Gellman’s Train The Trainers program. Sean is a proud member of The International Association Of Canine Professionals.

Meet Laura Video

Laura Morgan

Head Trainer/TGD Coordinator

Hi! I’m Laura, Sean’s right hand here at The Good Dog Training and Rehabilitation, and I will most likely be friends with you by the time you walk in our door 🙂 Before joining Team Good Dog in 2011, I found Sean when my own bad dog, Polar Bear, was at (beyond!) the point of needing professional help. After working with Sean and getting Polar Bear to a great place, I had fallen in love with training and started working for Sean. I was able to use my previous film industry experience and skills to help build the business side of TGD, and my knowledge of training difficult dogs to the advantage of all the dogs that come through the doors. I can’t wait to meet you and get you started on your own journey of an amazing relationship with your dog!

When Laura’s not filming or shooting Q&A Saturday, she’s on the phone with clients,  helping out with training, working one on one sessions, cutting videos, working on all things TGD, and anything else in between! 


Meet Tony Video

Tony Shields

Head Trainer

Hey guys, my name is Tony, head trainer here at The Good Dog. I started my dog training career in 1977, attending the Moorpark College for Exotic Animal Training, and for the following 10 years I trained dogs and a myriad of other animals for film and television. I worked exclusively for Walt Disney Productions, Columbia TriStar, Paramount Pictures, and Universal Pictures, with work on popular TV shows Happy Days, Laverne and Shirley, The Bionic Woman; and movies such as the original ANNIE, and Devil Dog: The Hound of Hell. I took a hiatus from dog training to raise my family and build a family business, and I met Sean when I was struggling to turn the corner with my dog-aggressive Rottweiler, Astro…and the rest is history! Astro is awesome and balanced, and I have been working with Sean and The Good Dog crew ever since. I am happy to be changing lives, one dog at a time.

Tony is our head board and train trainer here at The Good Dog. If your dog does a board and train, they will train with Tony, with Sean overseeing remotely or hands-on. 


Meet Brittany Video

Brittany Alexander

Head Trainer

Hi there! I’m Brittany, head trainer at The Good Dog Training and Rehabilitation. I first came to The Good Dog as a client with an out of control Min Pin, Hass. Despite having read and watched as much dog training advice I could get my hands on, I was only able to make marginal progress with my dog’s extreme behaviors over the years. It wasn’t until I found Sean that I was able to achieve a healthy lifestyle with Hass and leave all the stress behind. After experiencing firsthand the possibilities from using Sean’s approach and a few simple tools, I was beyond inspired! I wanted to help give that peace of mind to other dog owners who were struggling. Luckily Sean recognized my passion and was happy to add me to his amazing team. I’ve been training with The Good Dog ever since and I couldn’t be more excited to be involved!

Brittany is the head one-on-one sessions trainer here at The Good Dog. Whether you are coming to us, or we are coming to you, Brittany is one of the trainers you will be working with! She will also be working with your dog as a head trainer if you do a board and train with us.




TGD Trainer

Hey everyone, I’m Shelby! I’ve always had a passion for animals, and fancied myself a pretty savvy dog owner, until I adopted my young Boerboel, Samson. I was determined to do everything right – I read the books, went to training classes, socialized him with different dogs and people. But the more he matured, the more suspicious and insecure he got until he was snapping at strangers and getting into dog fights. I felt so hopeless! I devoured as much information as I could, and tried every training method out there, but nothing seemed to help.

Then I met Sean and Laura. They not only helped me curb my dog’s dangerous behavior, but they showed me how to be a believable leader who could guide him through life and make him feel safe. After my own experience with Samson and The Good Dog, I realized that I wanted to help troubled dogs and the people who struggle with them. I started working at a dog daycare and boarding facility so I could study and observe dog behavior while honing my handling skills, and I studied with Sean and Laura, working with them on a variety of dog behavior cases.

Eventually, I was invited to join the TGD team, and I happily jumped on board. Now I’m able to work dogs through their issues every day, and it couldn’t be more rewarding! I can’t wait to get to know you, and help you help your dog!




TGD Trainer

Hi! I’m Anri! I have had a passion for animals since I was little and would spend my time learning about animals in anyway I could. I loved watching Animal Planet and The National Geographic channel and realized that I wanted to work with animals.

I went to a vocational school for dog training in Japan for 2 years. Although studying in Japan set my basic knowledge about dog training, I knew that there were other methods I could learn and knew that there were many dogs that needed a different approach to what I have learned in Japan. After graduating vocational school, I came back to LA and worked at a veterinary hospital as a veterinary technician and then at a cage free pet hotel while attending workshops and seminars such as Training Cesar’s Way, LucasAgnew, Force Free method, Pack to Basics and T3.

After attending T3, I started studying with Sean and eventually, Sean welcomed me into his team! I would love to help and be a part of you and your dog’s new life!


I brought my dog, Pinto, to Sean with severe leash-reactivity and separation anxiety. After working with Sean, Pinto came back relaxed and non-reactive on the leash.– Ami B.
