The student has asked about using domain-specific vocabulary to improve a phrase related to her work training dogs that help in locating missing people. In this context, the most appropriate term to enhance the phrase without altering its meaning would be 'search and rescue dogs'.
This term specifically refers to dogs trained to find people who are lost or have been trapped during natural disasters, accidents, or other emergencies. Unlike 'working dogs', which is a broader category, or 'golden retrievers' and 'seeing eye dogs', which refer to specific breeds or types of service dogs, 'search and rescue dogs' conveys the specialized training and skill set these dogs can possess for the given task.
For example, bloodhounds are known for their incredible sense of smell and may be specifically trained as search and rescue dogs due to their ability to pick up and follow human scents over great distances and even after significant time has passed.
