Chicago-area sheriff’s K9 dies days after retirement ceremony

LAKE COUNTY, Ill. — The Lake County Sheriff’s Office is mourning the loss of a former K9 officer who died on Friday.

K9 Dax, a 10-year-old decorated sheriff’s canine, joined the department in 2015 when he was just 13 months old and served with his partner, Deputy John Forlenza.


The dedicated German Shepherd suffered an injury in the line of duty in early March while apprehending a fleeing suspect who deputies say had committed several felonies.

According to deputies, Dax suffered injuries to his neck and spine, resulting in temporary paralysis to his hindquarters.

Dax was later diagnosed with cervical and thoracolumbar Intervertebral Disc Disease (IVDD) and lumbosacral IVDD, which deputies say was exacerbated during the apprehension.

Following his injury, Dax went through intensive physical therapy but was retired from service in March, after his veterinarians determined that he would not be able to return to active duty. 

“K9 Dax will always hold a special place in our hearts, and we are incredibly saddened by his passing,” Lake County Sheriff John Idleburg said. “K9 Dax will be remembered for the lives he saved, violent offenders he apprehended, and drugs he kept from being distributed in our community. Please keep the Forlenza family in your thoughts and prayers.” 

During their time together Dax and Forlenza located over 400 missing endangered people and fleeing felons.

“There is no way to quantify or properly express what Dax’s service has meant to the Lake County Sheriff’s Office, the Lake County community, his supporters across the nation, and especially me. But I cannot refrain from stating that his service has been exemplary, and most importantly, he has saved countless lives, including my own. I am proud to have been his handler and best friend for the last nine years. Dax is a true hero and well deserving of the rest and love that waits for him in his retirement. I’d like to especially thank Dax’s supporters, team of veterinarians, trainers, the Lake County Sheriff’s Office, and my family and friends for all their support throughout his career,” Deputy Forlenza previously said.

After his retirement, Dax went to live with Forlenza and his family.

On Wednesday, a ceremony was held to honor Dax and his dedication to the people of Lake County.
