Mondy joined PCSO in July 2019 where he completed several trainings and received several certifications during his four years of service,

In late 2023, Mondy was diagnosed with Spinal cancer which cut his career short.

PCSO said Mondy’s favorite activity was riding in the patrol car.

“As we say our goodbyes, let us reflect on the memories that made Mondy an irreplaceable part of our lives,” PSCO said on a post. “Mondy came into our lives as a ball of fur, full of energy and curiosity. From the moment he clumsily pounced into our hearts, he brought an abundance of laughter and love. We will all miss you, Mondy! Thanks for being a great handler Lt. Wolfe and taking such good care of Mondy!!!”
