We started treibball training with Gwendy in August 2023 as a puppy at the age of 5 months. We like treibball very much and we plan to carry on to more advanced levels. We train in Zalaegerszeg, with Dr. Erzsébet Nagy in Zalai Dog School. Gwendy is a very fast learner, so we decided to try the TREIBBALL OPEN Christmas Cap on the START level, though Gwendy's work is far from reliable, but we are not in a hurry.
