DALLAS — Donna Rosen and her 6-year-old son, Braxton, may never know why their pet dachshund went missing for 13 months or what happened to him while he was gone.

Those answers, if they ever come, will have to wait. Only one thing matters now.

“Bobo is back!” Braxton proclaimed last Monday as he watched his mother cradle the chestnut-colored dog in a park near their home. “Hi Bobo. We missed you for a long time.”

Bobo has come a long way since he mysteriously disappeared from the Rosen’s Denton County home on July 25, 2016. Rosen said she doesn’t know how the dog got away, though she suspects he was kidnapped. What she does know is that she has looked for him every day since.

Rosen’s friend was driving on a mid-winter night 10 years ago, when she saw someone in another car throw what looked like an animal into a freezing pond. The friend rushed to the animal’s aid, then called Rosen.

It was a 4-week old dachshund puppy, and it stole Rosen’s heart.

“I rescued him from a bad situation,” she said. “He was always loyal and appreciative — it’s like he knows where he came from.”

From that day on, wherever Donna went, Bobo went, too. There could not be a more inseparable pair. That was, until the day Braxton was born.

“They’ve been together ever since,” Rosen said.

The dog became Braxton’s best friend. But for Braxton, Bobo was more than just a companion.

Braxton has ADHD and has experienced seizures since his first birthday. As the two grew up together, Bobo became Braxton’s emotional support dog.

Bobo was always there, until he wasn’t. On that July morning Rosen let Bobo and her other dog, Spike, outside to go to the bathroom in the gated area beside the house.

Spike soon returned. Bobo did not.

“Spike comes through the door. I say ‘Bobo’ and nothing,” Rosen said. “I thought maybe he had found something to play with. When I walked around to the side of the house, he wasn’t there. I started searching, and I’ve been searching ever since.”

For Rosen, a single mother, the weight of searching day and night took a physical toll. She has an intestinal disease and was in remission, but the stress caused her health to deteriorate.

[naviga:h3]THE DISCOVERY[/naviga:h3]

On the morning of Aug. 2, she was scrolling through an Oregon found pet’s Facebook page and noticed a dog’s picture that stood out. She was certain it was Bobo.

Rosen reached out to the family immediately. Kara Schendel and her boyfriend, Dan Burnett, had found the brown dachshund running by the railroad tracks where they lived in Hubbard, Ore.

When Schendel learned that Rosen was from Texas, it hit her “that she loved the dog so much that she found it in this little tiny town.”

So she and Rosen started talking. Sure enough, there were similarities between the dogs they described. But there was also a glaring difference.

The dog in Oregon was described as partially blind and deaf, although Bobo had been fine the last time Rosen saw him.

Rosen made a FaceTime call and when she called Bobo’s name, he began looking around for her.

“Immediately when the camera turned around on him, I knew it was him,” Rosen said.

[naviga:h3]FINALLY HOME[/naviga:h3]

On Aug. 11, Rosen flew to Oregon to reunite with her other “child. She returned to North Texas with Bobo and surprised an unsuspecting Braxton.
