From 1995 on , Ingmar participated and succeeded in over 80 IPO and Schutzhund/IPO trials ,
on different levels and with more than 50 different boxers: both his own and boxers that were trusted to him for training. Besides these trials , he participated in BH, AD , German ZTP and Selection (Belgian and Italian).

His method of training focuses on the individual temperament and qualities of every single boxer and is largely based on the positive reinforcement techniques as established in the Pryor-Clicker method.

Ingmar : " I want to thank and to express my gratitude to the owners of the boxers who were trusted to me for training . I learned a lot from them. And of course , training a beautiful boxer is all the more gratifying. Without the trust of these people I would not have been able to do what I love definitly most : educating boxers on a regular basis. Thank you!"
