The first and only book built entirely for the IGP tracking phase, from a World-Champion coach. It ships with two apps, a private community, and a full year of monthly coaching with Lars Lentz.
Founding bonuses close July 31. The 12 monthly seminars with Lars and the lifetime Pruf discount are founding-only and go away when the doors close.
Tracking is the phase everyone trains last and understands least. One chapter in the back of an all-phases manual, then you hope it holds up on trial day.
So you survive it. You get a passing track, you tighten the line at every corner, you fight a nose you cannot smell with, and you wonder why the dog who looks brilliant in the yard falls apart on a cold corner.
It was never the dog. Nobody ever handed you a logical, start-to-finish system built only for the nose. Now someone has.
Lars Lentz has coached IGP World Champions. The shift that built them is one sentence: stop correcting the dog after the mistake, and build the track so the dog never gets to make it. He calls it Logical Dog Training.
Dogs trained this way do not just pass. They post the scores you chase for years: Liam O'Keeffe's 99 in tracking and Irish National title, Jennie Fincham's 97 in the A with Best Tracking. For the first time, the whole system is written down.
And we wrote it to be read: a seventh-grade reading level on purpose, clear and a little funny, because we are responsible for you understanding it. We are not selling you a book. We are selling you a result.
One founding membership. The book, the tools, the coaching, and the people, all in one place.
~80,000 words, ~375 pages. The only book built entirely for tracking. Ebook the day you join. Want paper? Order it at our cost, ~$27 hardcover or ~$13 paperback, no markup.
The AI that answers your questions from the book and the 2026 FCI rule book, in the field, on the spot. Ready the moment you buy.
Log your dog's whole training life by voice in 30 seconds. Free to use right now at pruf.training. Founding members lock 30% off for life ($10/mo vs $13.99) when it reaches the app stores.
A full year of World-Champion coaching, live Q&A, recorded to the library. Founding-only. This is the headline, and it is gone when the doors close.
For the truck and the field. Put the system in your ear on the long drive to training. A launch bonus.
Watch the exercise, post your track, get a real answer. Lars wanted to charge $300 for this. It is free with your purchase, plus direct access to Lars and Eric inside.
Add the pieces up honestly and they clear well over $2,000, with the year of seminars carrying most of it. Your founding price is $200. One time.
The dog was never the problem. This proves it.
"375 pages. I'll never find the answer on the field."
That is exactly what Jack is for. Ask in your own words, get the answer with the reference, on the spot.
"I'm a beginner."
Good. It is built in order, seventh-grade level, nothing skipped, and you have the community and Lars's monthly seminars.
"My dog is soft, and I'm starting a green dog later in life. Too late? Too heavy-handed?"
Lars: never too late. The method is 80 to 90% positive. In ten years he has not seen a dog that could not learn to make a B-score on an IGP1 track, as long as it wants to eat the food.
"Do I get a printed copy?"
If you want one, at our cost: ~$27 hardcover or ~$13 paperback, no markup.
"What's Pruf, and do I have to use it?"
It logs your dog's whole training life by voice. You do not have to use it. Free now at pruf.training; founding members lock a lifetime 30% discount for when it hits the app stores.
It was never the dog. It was the missing system. It exists now, with the tools, the coaching, and the people to make it stick, for $200 until July 31. Read it with a smile on your face.
