Sound familiar?
The door opens and your dog is gone.
You block it with your leg. You yell their name.
You chase them down the block.
And there's a baby gate in every doorway.
Why a gate doesn't fix it
A gate only works when it's closed.
Boundary Barrier teaches your dog an invisible line instead.
The same door drill works on any interior doorway. Fewer baby gates.
And the road boundary covers property lines and the rooms inside your house too.

How I teach the line
No treats. Ever. I praise with my voice and my hands.
Be clear. Be fair. Mean what you say.
You'll see how I teach the line at the door, in the yard and at the street.
Your dog learns where the line is, even with the door wide open.
Fair, and never more than your dog needs.
I'm Lee Seibold, "Dogtor Lee."

I've trained thousands of dogs over 14 years, and more than 1,300 dog owners use my app.
I've worked with puppies that bite everything, big dogs that drag their owners down the street, and dogs that had already been through other trainers. The same principles work across all of them: be clear, be fair, and mean what you say.
Boundary Barrier is how I teach that line, in 4 short lessons.
This is for you if:
- Your dog is out the door the second it opens
- You're tired of blocking the door and chasing your dog down the block
- You want fewer baby gates in your house
- You're OK being clear and fair with your dog
This isn't for you if:
- You only want to use treats and never correct your dog

Questions
How long is it?
4 short lessons, about 10 minutes total. Binge it tonight, use it tomorrow.
Do I need a gate?
No. This teaches your dog the line itself, not the gate.
Is it only for the front door?
No. The same drill works on any interior doorway. The road boundary also covers property lines and interior rooms.
What if my dog is stubborn?
Some dogs get it in minutes. Stubborn ones may need a few more short sessions.
Wasn't this in the Behavior Fixes Bundle?
It was. Now it's its own course. Already bought the bundle? You still have it. Just log in.
Do you use treats?
No treats. Ever. I praise with my voice and my hands.
Is this harsh? Do I have to be tough on my dog?
No. You don't need to dominate your dog or punish them harshly. I teach fair consequences, matched to your dog, never more than your dog needs.
What if I get stuck?
If you want me to look at your dog, send me a video for a one-time $17 Personal Video Review. You can add it at checkout.
How do I get access?
Right after checkout you get an email with your login. Watch on your phone or computer. Access is for life.
What if it's not for me?
Email [email protected] within 30 days and I'll refund you. No questions asked.
