Domenik Girardi

My name is Domenik Girardi and I was born in Mannheim, Germany but grew up in Chicago, Illinois. I started training for schutzhund in 2016 with a local training group and quickly developed a passion for both training and helper work with my first dog, Mile. Since then I’ve been working hard to get onto the trial field as a handler and as a helper. I would like to thank the Helper Selection Committee for trusting me with the safe and consistent testing of the dogs at the National Sieger Show and of course my amazing wife Natalie for the unconditional love and support. I’d like to wish the best of luck to all of the competitors!
