Nearly 7 in 10 owners of dogs with behavior issues carry a real, measurable mental load from it. Reactivity is hard, and it is not your fault.

Why choose Hephra?
A good trainer helps, but only an hour a week. The videos are inconsistent. The courses are not personalized to you and your dog. The classes are overwhelming. All of them leave you alone the moment your dog reacts.
Hephra is built for that moment: real-time guidance on every walk and a personalized training plan, with a certified trainer when you want one, so the improvement is inevitable.

We built this because of Daisy.
We built this because of Daisy.


I'm Jonathan, and Hephra started with Daisy, my mini goldendoodle. In the early days, I couldn't walk her past another dog without it turning into a lunging, barking mess. I had no clue what to do. I watched hundreds of YouTube videos, tried online courses, and worked with trainers. I tried everything I could and still froze in the moments that mattered: when she'd react and there was no immediate help on the walk.
What finally helped wasn't more information. It was catching her before the reaction instead of after, staying consistent every day, and finally being able to tell that it was working. That's the whole thing, really: I didn't need to know more, I needed help in the actual moment and proof we were getting somewhere, so I could stop feeling helpless and start believing it would get better. We’ve come a long way from those early walks.
I'm not a trainer, but I'm an owner who has lived through the same reactive experiences as you, and those exact lessons are what James and I are building into Hephra: a coach in your ear the moment it matters, a curated plan from certified reactive-dog trainers, and real proof you can watch your dog improve. It's the help I wish I'd had on every walk, and the thing no reactive dog and owner should have to go without.

Frequently Asked Questions
Frequently Asked Questions
Is Hephra worth it?
A trainer costs $50 to $150 a session, and you still walk alone the rest of the week. Hephra is with you on every walk, for less than one session a month.
What happens when I reserve?
$25 holds your spot in the first production run and locks in early access to the device and app. It's fully refundable and if you change your mind any time before your kit ships, you will get a full refund, no questions asked. You don’t choose a plan now, you pick Solo or Coached when we launch.
Isn't a voice in my ear just distracting?
It's not constant chatter. Hephra stays quiet until the pre-reactive moment, then gives one short cue, early, before your dog is over threshold. The goal is to help you act sooner, not talk over the chaos.
Does Hephra require a subscription?
Hephra works best with a subscription which gives you access to progress tracking, the full protocol library, and real-time guidance during walks. A free tier is always available.
How does the coaching work?
Sensors on the collar and leash read what your dog's body is doing in real time. An IMU catches the freeze, the orientation shift, and the lunge or pull before it fully happens; a microphone picks up barking and whining; a leash-tension sensor feels exactly when your dog braces or hits the end of the leash. When you need assistance, Hephra speaks in your ear with the next move, something like "Daisy's locking on, start your 'Find It' now, before she lunges." After the walk, every moment is mapped to where it happened using your phone's GPS, so you can look back and ask why things played out the way they did.
How is this different from a smart collar like Fi or Halo?
Smart collars track where your dog is or how they slept. Hephra is built to train, so it reads the moment your dog reacts and coaches you through it.
Will it work for my dog?
It is built for the everyday stuff: lunging, barking, and fixating on other dogs, people, or bikes. For serious aggression like biting, start with a veterinary behaviorist, and Hephra works right alongside that.
Is the device safe?
The device doesn't hold your dog. Your collar and leash do that, exactly as they do now. Hephra's sensors sit alongside them, so if it ever failed you'd lose data, not your grip on your dog.
Do I need a trainer?
Everything you need is built in: the protocols, the coaching, and the data that shows what is working. If you want a real person too, the Coached plan adds a certified trainer who reviews your progress.
When does Hephra ship?
We are targeting Q4 2026. Reserving now puts you in the first production run, with earliest access to the device, the app, and everything we build.
