Oreo survived heartworm, but he still needs your help!

This is three-year-old Oreo, a remarkably brave dog whose life has been a series of heartbreaks, miracles, and second chances.

Oreo’s story begins in Houston, Texas, at BARC—one of the highest-kill shelters in the country. His owner had suffered a devastating tragedy: her home burned down. In the chaos and grief, the Red Cross advised her to temporarily place Oreo in the shelter until she could find stable housing. But when she returned to bring her boy home, she was told she had unknowingly signed a surrender form—and that Oreo was already scheduled for euthanasia.

They refused to give him back. That same day, Mary's Dogs reached out to a rescue to save Oreo’s life. They tried over and over to find his owner, but they never could. So the rescue brought Oreo all the way to New England, hoping that if she went looking, she’d one day find him safe and loved. But Oreo’s challenges weren’t over. One terrible night, he spiked a dangerously high fever. He stopped eating, stopped drinking, and could barely lift his head. Mary carried him into the vet, and the news shattered her—Oreo was in heart failure.

Tests revealed he was heartworm positive, and severely so. With intensive care, close monitoring, and sheer determination, Oreo slowly stabilized. After six long months of treatment, countless vet visits, and so many nights spent hoping he’d keep fighting… Oreo tested negative.

He survived.

Today, this miracle dog has been chosen by a wonderful family in upstate New Hampshire for a foster-to-adopt home. After everything he has endured, Oreo finally has the future he deserves—a warm, safe home filled with love.

But Oreo’s journey came with enormous medical costs, travel expenses, and ongoing care that rescues like Mary's Dogs can only cover with help. Please if you can, any amount would help and no amount is too small.

Thank you for your continued support.
