U.S. Customs and Border Protection (CBP) has announced the birth of Dolly, the first foal ever born in the Big Bend sector of Texas. This marks a significant milestone in the agency’s long-standing tradition of using horses for border patrol operations. Dolly was born in Sierra Blanca, about 100 miles east of El Paso, where she is being cared for alongside her mother, Juanita, at the agency’s stable. Her arrival highlights the CBP’s commitment to maintaining a strong mounted patrol unit in this remote region.
Dolly is unique among the patrol horses due to her striking blue eye, making her easily identifiable within the stable. The Big Bend sector is known for its rough and difficult terrain, where vehicles often struggle to operate. Horses have been essential in helping agents reach remote areas, and Dolly will eventually join the ranks of patrol horses that assist in border security efforts. Her birth ensures that this traditional yet effective method of patrolling remains in use.

Horses Enhance Border Security and Strengthen Community Ties in Remote Areas
In a statement, Border Patrol emphasized the importance of horses in their work along the U.S.-Mexico border. Mounted agents are able to track movements, detect illegal activity, and navigate areas inaccessible to vehicles. The use of horses not only enhances operational effectiveness but also helps strengthen relationships between the Border Patrol and the local communities they serve.
Dolly’s name was chosen from a list provided by students in the Sierra Blanca Independent School District, reflecting local involvement in the agency’s efforts. As she grows, she will be trained to handle the physical demands of patrolling the border, ensuring that she contributes to national security. Her birth represents both a continuation of tradition and a new chapter in the agency’s use of horses for border enforcement.
