UPPD Canine Unit

Sgt Mackey and K9 Officer Zzisa Officer Wesley and K9 Officer Uman

In 2014 K9 Officer Zzisa joined the UPPD, paired with partner Sergeant Sean Mackey. In November 2020, K9 Officer Uman joined the UPPD, paired with partner Officer Julie Wesley.

Zzisa and Uman, both Labrador retrievers, are certified ordnance detection and evidence detection canines. As sworn members of the UPPD, Uman and Zzisa work diligently to ensure the safety and security of the University City community.

The K9 units respond to calls about unattended packages and perform building sweeps before large-scale events and visits by dignitaries. They can also be found undertaking regular patrol of Penn’s campus and the surrounding area.

Zzisa joined the UPPD from the PennVet Working Dog Center (WDC). Uman is Zzisa’s granddaughter, a pup bred by the WDC to dam Pinto and sire Boomer.  For more information on the Penn Working Dog Center, please visit:

In September of 2013, Officer Socks graduated from the first class at Penn Vet Working Dog Center, and joined the UPPD as the first canine officer. Socks was paired with her partner Officer Julie Wesley, and was certified in ordnance and evidence detection. She was named in honor of Socks Lavoie (handler Sue Lavoie), who was deployed to the Staten Island Landfill following the attacks of 9/11. Socks passed on July 20, 2020 at the age of 8, surrounded by the love of Officer Wesley and her other family members. We are grateful to K9 Officer Socks and her years of service to the Penn Community.
