The Puzzle Dog team

Puzzle Dog is a one-women / one-dog business:
Tessa and #PuzzlePuck are the ones that do it all: teach, sew, puzzle, demo, finances, logistics, emailing, website building, creating content 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, because we keep on learning and have many cool ideas that we want to share!

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 his owner too!

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

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. When we moved from Norway to Canada in 2017 I studied to become a certified ‘Hersenwerk for dogs’. And since then I also got the amazing job of tutor and manager international for Hersenwerk for dogs.

Since 2017 we have added knowledge and skills to our 'backpack' and we will probably never stop doing that. There is so much to learn about dogs and so much research is being done these days: the learning won't ever stop.
