I adopted Bailey in 2018. She had been picked up by Moreno Valley, California, Animal Control. She had road rash and a fear of kennels.

My mother-in-law adopted her initially, but Bailey could not get along with my mother-in-law’s other dog.

I took her in. After a day or two, I realized Bailey had been through something terrible. She cried all night and would not sleep. She was aggressive toward my other dogs and reactive in public. No one could pet her without being snapped at. She could not be crated without extreme panic. She also guarded resources.

I took her to several trainers and was told to put her down. Determined to find a solution for her, I started studying dog behavior, dog psychology, and dog training.

I applied what I learned. It took about two years to fully understand dog behavior and training, and to fully rehabilitate and train Bailey. Along the way, there were fights. I got bit a few times, and my husband got bit a few times. There were moments when I thought there was no hope. Somehow, deep down, I knew she just needed help, so I stuck with it. I kept working with her and learning. Eventually, she learned to trust. She learned to play. She learned to share. A beautiful, soft, loving side of her came out.

Bailey’s progress was visible to other people. Friends and family eventually started asking for help with dogs they knew. Over several more years, I became a dog trainer.

Then, in 2024, Peaceful Coexistence Ltd. was born in Bailey’s honor. It is a nonprofit organization designed to help dog parents experiencing similar situations.

Bailey became the dog who helped rehabilitate and train other dogs. Her story gave hope to other pet parents facing similar challenges. She had patience with reactive dogs and a softness with scared dogs. When she came to my classes, people and dogs would meet her, then hear her story and become inspired to see that aggression and reactivity could be healed.

Bailey taught us that dogs experience trauma. They can have PTSD, anxiety, and depression. She also taught us that dogs can heal. They can recover.

Bailey was my best friend. My soul dog.

Bailey passed away naturally in December 2025. It was the hardest loss I have ever faced.

Her legacy lives on through Peaceful Coexistence, and her story continues to inspire pet parents who face behavioral challenges and feel lost about what to do. Her story inspired a nonprofit that makes dog training free and provides resources to pet owners.

Bailey will never be forgotten. Her legacy will continue to change the world for dogs.
