The Puzzle Dog team

Puzzle Dog is a one-women / one-dog business:
Tessa and #PuzzlePuck are the ones that do it all: teach, puzzle, demo, finances, logistics, sew, emailing, website building, course and content creating  and everything else that needs to be done running a business!

Our passion for Hersenwerk and puzzles is what started it all. First we focused on sewing and selling puzzles and over time courses, events, patterns and more have been added. We keep on learning and developing!

All our services and products come together in our wish for every dog to have a happy, pain free, comfortable, enriched and fun life! And their human too! Our approach is 100% pain and aversive free. 

We send out newsletters to keep our fans informed about our activities, services and products. Want to stay informed too? Please sign up here: NEWSLETTER


Puzzle dog in the media

Puzzle Dog has been in the media a couple of times!

The episode of NSK9 (recorded in Dec 2020) can be watched on YouTube now!

And this is a little trailer of our appearance in A Dog's Life, recorded Aug 2023 and aired March 24th on Eastlink TV

Keep on learning!

Being good in what we do and becoming better all the time: that's our goal for Puzzle Dog.

After a career as a quality manager, facility manager and consultant in several branches I started 'studying dogs' in 2014 after our first move abroad - from the Netherlands to Norway.
In 2018 I founded Puzzle Dog and I have since become tutor for Hersenwerk for dogs (2018)and a Dynamic Dog practitioner (2022).
