The dogs other trainers send away are ours to keep.
Severe aggression. Deep-rooted anxiety. Reactivity that has failed every other protocol. K9 Optima was built for the cases nobody else will take.
The Infinite Approach
Most trainers address behavior. We address the nervous system. Identifying the neurological driver before touching a single command is why the cases other trainers give up on are the ones we are built for.

Where do you start?
Two ways into the work, one for owners and one for trainers.
For dog owners
Your dog isn't broken.
The approach was wrong.
If you've tried multiple trainers and you're still stuck, the problem isn't your dog's behavior. It's that nobody identified what's actually driving it. That's where we start.
- Ā Read the book: understand the framework behind 6,000+ cases
- Ā Join the community: 350+ case studies, weekly live Q&A with Josh
- Ā Work with us: virtual sessions or in-person in Antioch, CA
For professional trainers
The cases you're sending away are solvable.

Meet the helpers
The dogs who do the real work.
Reactive dogs do not recover in a vacuum. They recover around other dogs who know the job. These are ours. Each one is trained for a specific role in a session.
Hover a card to see exactly what they do. On a phone, it is already open.
Boo has worked more than 5,000 reactivity cases. She is usually the first dog we bring in. Calm and social, she lets us read how your dog responds to a neutral dog. When your dog settles and gets curious, Boo is there to invite play.
Gigi stays still and simply wags her tail. She holds soft eye contact and makes no sudden moves, which raises the bar on size and on being looked at. Once your dog is comfortable, she is happy to meet them.
Waffles is a skilled trigger dog, trained to bark on command. He is especially effective with dogs who tend to pick fights with larger dogs, on our terms and at a distance the dog can handle.
Juju is trained to bark on command and create controlled conflict. She most often works with dogs who have predatory issues, in a setting where we stay in control the whole time.
