Every Tuesday evening, Marine veteran James Heisterman heads to the local bowling alley accompanied by his service dog, Tiberius. The two-year-old Labrador and golden retriever mix remains completely composed amidst the clatter of falling pins and lively chatter, keeping his attention firmly on his handler. He acts as a physical buffer if strangers approach too closely or steps in to interrupt PTSD symptoms by resting his chin directly on Heisterman’s leg.

“Usually at the end of the night when we’re all putting our gear away and changing shoes and getting ready to pack and go home, that’s when I’ll let other teammates or other people in the league come and visit with him and give him a little bit of attention when he is off duty,” he remarked. “He loves it.”

This enjoyable weekly outing would have been entirely out of reach merely six months prior, before Heisterman was paired with Tiberius. The Florida resident previously flew medevac missions as a Marine helicopter crew chief throughout Desert Storm and numerous other military engagements.

He returned home carrying the heavy burden of post-traumatic stress disorder alongside a permanent V.A. disability rating.

Nearly ten years ago, he married his wife, Linda. The two originally formed a friendship at the age of 12. Following high school graduation, he enlisted in the U.S. Marine Corps while she mailed letters and care packages from college. Eventually, they lost touch over the years, each starting separate relationships and raising children before serendipitously crossing paths again in their hometown while returning to care for elderly relatives—ultimately falling in love.

Once wed, Linda Heisterman began to witness firsthand the severe toll PTSD exacted on her husband.

“PTSD is just such a horrible, horrible thing because it isolates the individual and it causes them to believe a non-reality,” she stated.

“It lies to you,” he concurred.

A Life-Changing Service Dog Partnership

Finding relief finally came in late May of this year when they traveled to Orlando to be matched with a service dog from Canine Companions. This national nonprofit trains and places service dogs with veterans managing PTSD and other individuals facing disabilities completely free of charge. Handlers and their canine companions spend two weeks training intensely at a regional campus prior to graduation.

Linda Heisterman expressed astonishment at the immediate bond forged between her husband—whom she frequently calls Jim—and Tiberius.

“The first day they met, we brought Tiberius into our dorm room, and James sat down beside Tiberius, and the first thing Tiberius did was take his paw and put it on Jim’s hand and look at him,” she recalled. “It just hit both of our hearts because we both felt like he was just saying, ‘I’m here. I’ve got you.’”

That sentiment has proven consistently true. Heisterman frequently wakes during the night to find Tiberius draped across his chest. This tactile pressure helps halt the relentless nightmares and night terrors that plagued Heisterman for years, leaving the couple utterly exhausted from chronic sleep deprivation.

To assist Tiberius in precisely detecting shifts in Heisterman’s heart rate during sleep, they utilized an innovative biometric tool developed by Canine Companions called CanineAlert. At night, Heisterman wears an ankle vitals-monitoring device, while Tiberius wears a small collar monitor. If Heisterman’s heart rate crosses a designated threshold, the dog’s collar gently vibrates, signaling the need to intercept a developing nightmare.

“Sometimes I wake up to him laying across my chest using tactile pressure to wake me up from a nightmare before it even starts now,” he noted. “My nightmares have decreased probably about 65% easily.”

During daytime hours, Tiberius actively positions himself as a protective barrier in crowded spaces. When the canine senses rising anxiety in Heisterman, he delivers reassuring pressure by resting his chin on his knee or stretching across his legs. He possesses training in over 50 specific cues to manage various scenarios.

Because Heisterman experiences impaired grip strength from crushed hands and wrist screws, Tiberius eagerly retrieves dropped items like keys or a watch.

“If he’s ready to go and we’re ready to go, he’ll pick up his own leash and hand it to me like, ‘OK, let’s go,’” Heisterman explained. “He’s actually given me a purpose again. I can get out and do things more in public and have confidence that I have someone with me that’s trained and can handle the situations properly. We’ve come a long way.”

While intensely focused while on duty, Tiberius transforms into a playful goofball once off the clock, delivering abundant laughter and optimism. Heisterman has successfully decreased his dependence on medications he relied upon for a decade, according to his wife.

“There were days James couldn’t get out of bed. He didn’t want to interact with society. He was angry all the time. With PTSD, you never know how it’s going to come. You never know what form it’s coming in. You never know what to expect. So you are battling something that you just can’t put your finger on. You think you have it figured out and then it comes in another form,” she observed. “And what I’ve noticed more than anything is Tiberius has calmed that sea that was always raging inside of him, and I have not seen anything else in his life as impactful as Tiberius has been.”

To celebrate the profound difference Tiberius has made, the couple launched an uplifting Facebook page titled “Tiberius – The Veteran Service Dog” to highlight how these animals can transform veterans' lives.

“We try to keep it light. We try to keep it positive,” she said. “We try to make it fun, informative, educational.”

The Urgency of Puppy Raisers for Future Service Dogs

The couple encourages animal lovers to volunteer as puppy raisers for Canine Companions. These volunteers welcome an 8-week-old puppy into their home, providing care and teaching foundational obedience for 14 to 16 months with organizational support before sending the dog back for advanced service training.

Canine Companions and similar organizations face a constant shortage of puppy raisers nationwide. Linda Heisterman noted that her husband endured a 15-month waiting period after approval before finally partnering with Tiberius.

Given that suicide remains a critical concern among veterans struggling with PTSD, James Heisterman emphasizes the pressing need to deliver service dogs to veterans rapidly.

“I’ve lost several friends post service to their own hand, and I can only imagine, what if Darren had a service dog? Would he have pulled the trigger? What if Brad had a service dog? Would he have pulled the trigger? I don’t think so, because the love that these dogs give is just unconditional,” he expressed. “It can take a bad day and just turn it around into a bright day because all it takes is for him to do something silly and make you laugh. How can you not love that? If you’re just having a rough day and he senses it and he comes over and lays his head on your arm or cuddles up next to you or comes lick you on your face, that’s just an amazing thing.”

He remains profoundly thankful for Tiberius and the community he discovered through Canine Companions.

“I knew I was getting a highly trained service dog tailored for my needs, but I didn’t know I was gaining a secondary family through Canine Companions,” he said. “Every graduate that has graduated with a service dog from Canine Companions is part of our support group.”

Looking ahead, the Heistermans anticipate celebrating their 10th wedding anniversary in March, visiting their three adult children, and planning future travels together. They are thrilled to rebuild and envision new horizons thanks to their remarkable service dog.

“It’s definitely been life changing,” James Heisterman concluded.
