Niko was selected by Jason Posel to replace K-9 Shadow after his retirement. Niko was trained by Posel from the time he was 12 weeks old. Niko was a Belgian Malinios and was the first of that breed to join the K-9 unit. Posel’s work with Niko as a puppy helped inspire the current puppy cadet program. Niko passed away suddenly at his home when he was 8 years old.
