Good Samaritan Law: Veterinarian
A licensed veterinarian or a veterinarian student, under the direction of a licensed veterinarian, who, without compensation, provides care or assistance to an animal in an emergency where the animal's owner is not available, 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.
