Ten years ago, the veterinary staff at the University of Minnesota’s College of Veterinary Medicine experienced a truly extraordinary moment that would forever remain etched in their memories. When a mare named Princess arrived at the teaching hospital in St. Paul, no one—not even her owners—realized she was pregnant. But the biggest shock was yet to come.
Princess wasn’t delivering a single foal. She was giving birth to twins. In the equestrian world, this news sends shivers down the spines of even the most experienced vets. As the university would later explain, “fewer than 1 percent of twin foal births are successful.” The odds were stacked impossibly against these two precious lives from the very start.

A Fight for Survival
The challenges facing newborn Henry and William were severe. Twin pregnancies in horses are notoriously difficult, often resulting in developmental complications that can be life-threatening. These brothers arrived into the world facing multiple serious conditions that veterinarians had feared:
- Angular limb deformities
- Septic infections
- Insufficient colostrum (vital antibodies from mother’s milk)
- Breathing abnormalities
- Blood disorders
- Ruptured bladders
Any one of these conditions could have been catastrophic. Facing them all simultaneously, Henry and William’s survival seemed nearly impossible.

Three Weeks of Intensive Care
What followed was an incredible display of dedication from the veterinary team. For three grueling weeks, the staff at the University of Minnesota’s College of Veterinary Medicine provided round-the-clock care and rehabilitation. Every moment mattered. Every medical intervention was crucial. The team worked tirelessly, treating infections, managing breathing support, addressing orthopedic concerns, and nurturing these two fragile foals back from the brink.
The hospital’s commitment paid off. Against all odds, Henry and William not only survived—they thrived. After those critical first three weeks, the twins were finally strong enough to go home with their grateful owners.

A Year Later: A Happy Ending
Fast forward one year, and the story gets even better. Both Henry and William had blossomed into happy, healthy, energetic foals. What once seemed like an impossible dream had become a beautiful reality. These twins represent the very best of modern equine veterinary care and the incredible resilience of horses themselves.
