La. R.S. 37:1731(C)
Good Samaritan Law: Veterinarian
A veterinarian who, in good faith and voluntarily, provides or arranges emergency care to an animal at the scene of an emergency will not be held legally responsible for acting or failing to act. Generally, Good Samaritan laws only offer protection for those individuals who provide care during spontaneous emergencies unrelated to volunteer deployment.
Gratuitous service at scene of emergency; emergency care at hospitals; limitation of liability

No veterinarian licensed under the provisions of Chapter 18 of this Title, who, in good faith gratuitously renders emergency care or services or assistance at the scene of an emergency to an animal or animals in need thereof, shall be liable for any civil damages as a result of any act or omission by such person in rendering the care or services or assistance, or as a result of any act or failure to act to provide or arrange for further veterinary medical treatment or care for the animal involved in the said emergency.
