After a gunshot injury cost K-9 Ace his left front leg and ended his law-enforcement career, Deputy Natalie Oestreich faced an unusual professional transition: selecting another dog. Her choice was Vader, a 15-month-old German Shepherd donated to the Polk County Sheriff’s Office by HBK-9.
The new partnership follows a difficult sequence for the Florida K-9 team. Ace was shot in the chest in August while working in the line of duty. His injury required the amputation of his left front leg, and although he recovered from surgery, he could not return to service.
Retirement separated two roles that had previously existed together. Oestreich needed another law-enforcement partner, while Ace moved from operational work into life at home with his handler. That arrangement gives his retirement continuity: local coverage of his recovery confirmed that Oestreich would keep him for the rest of his life.
Ace later received a custom prosthetic limb made without charge by Westcoast Brace and Limb. Early in the fitting process, he needed support from a walking harness. Dr. Kerry Jackson of Polk County Animal Control later said Ace could walk independently with the prosthesis and was running and jumping. The device was intended for walks and selected activities rather than continuous wear, with follow-up checks planned to assess fit and alignment.
Vader’s selection followed formal outreach
Vader did not arrive through a direct, informal handoff to Oestreich. After learning about Ace’s injury and retirement, Herb Bennett of HBK-9 contacted the sheriff’s office through its chain of command and offered to donate a replacement dog.
Bennett then presented Oestreich with multiple dogs and allowed her to make the first selection. We just went through the selection process, and I gave Natalie first choice out of all the dogs I showed, and she has selected her replacement dog, Bennett said.
Oestreich chose Vader, and the sheriff’s office welcomed the young German Shepherd to its K-9 team. The sequence matters because a working-dog partnership is not established by donation alone. In this case, the agency was involved, dogs were presented for consideration, and the handler made the final choice among those available.
The available details do not identify the specific criteria Oestreich used to select Vader. They also do not establish his prior training, future specialty, expected duties or the date he will begin operational work. His age and breed are known; his eventual assignment is not. Selection marks the beginning of the partnership rather than proof that a dog is ready for deployment.
That distinction is especially important with professional dogs. Training and behavior work are individualized processes, and qualifications matter when outside expertise is involved. The American Kennel Club’s overview of behavior professionals notes that canine behavior work is broadly unregulated and advises examining recognized credentials, practical knowledge and continuing education. Vader’s law-enforcement preparation has not been detailed, but the same general principle applies: a title or breed alone does not document a dog’s training.
Ace’s career ended because of a serious line-of-duty injury, not because the partnership failed. Vader’s arrival therefore represents both continuity and a reset. Oestreich remains Ace’s caretaker in retirement while beginning a separate working relationship with a younger dog selected through the sheriff’s office and HBK-9.
For now, the verified transition stops at that selection. Vader has joined the team, but his operational timetable remains undisclosed. Ace, meanwhile, retains a permanent place in Oestreich’s home after losing his place on active duty.
