May 12, 2025 (LA MESA, Calif.) – A patrol K-9 serving with U.S. Customs and Border Protection (CBP) is currently under observation after receiving emergency treatment for a rattlesnake bite at
Pet Emergency & Specialty Center (PESC) in La Mesa, part of Thrive Pet Healthcare’s nationwide community of veterinary hospitals.
According to CBP, the K-9, Boo, was bitten while on duty on Friday, May 9, and was quickly airlifted to PESC, where the hospital’s emergency and critical care team delivered lifesaving antivenom and supportive treatment.
“Our team was prepared for this type of emergency and acted quickly to save Boo’s life,” said Dr. Jennifer Willey, Medical Director at PESC. “Thanks to the rapid response from Boo’s handler and the collaboration with U.S. Customs and Border Protection, Boo was able to receive timely care.”
“The entire U.S. Border Patrol, San Diego Sector family is encouraged by the progress K-9 Boo is making,” said CBP Acting Chief Patrol Agent Jeffrey Stalnaker. “His strength and resilience reflect the very best of our agency, and we are standing by him every step of the way. Our four-legged partners are treated as equals, serving with the same courage and commitment as their fellow Border Patrol agents. I sincerely thank each of the medical professionals who swiftly came to Boo’s aid.”
Rattlesnake bites can be fatal if not treated quickly. Immediate veterinary attention and the timely administration of antivenom greatly increase the chance of survival and full recovery.
Stay Alert: Snake Season is Here
With warmer weather, venomous snakes become more active, especially in areas where people and pets may be hiking or working outdoors. Rattlesnakes are the most active between April and October, particularly at dawn and dusk.
Thrive Pet Healthcare encourages pet owners to take the following precautions:
Keep pets leashed and stay on open, visible trails during walks or hikes.
Avoid tall grass, brush, and rocky areas where snakes may be hiding.
Consider rattlesnake avoidance training for dogs in high-risk areas.
Talk to your veterinarian about the rattlesnake vaccine, if available in your region.
If a bite is suspected, seek emergency care immediately. Do not wait for symptoms to appear!
“Boo’s case is a powerful reminder of how critical fast action can be when it comes to venomous snake bites,” said Dr. Willey. “We’re honored to play a role in his care and recovery.”
