Who is responsible for making horses available for inspections by the Commission veterinarian?

The trainer of the horse holds the responsibility for making horses available for inspections by the Commission veterinarian. This is primarily because trainers are directly involved in the day-to-day care and management of the horses in their charge. They are in close contact with the animals and are responsible for their health, training, and overall welfare.

During inspections, the veterinarian may need to check the horses for health issues or eligibility for competition. Since trainers have the most intimate knowledge of their horses, including any concerns or conditions that may require attention or monitoring, they play a crucial role in facilitating these inspections.

In this context, the owner, while they may have a vested interest in the horse's health and performance, typically relies on the trainer to manage these aspects. Racetrack management does provide the infrastructure for the races and veterinary inspections but does not take on the responsibility of ensuring horse availability for examination. The Commission veterinarian is tasked with performing the inspections but cannot be responsible for making the horses available themselves. Thus, the trainer's direct involvement in this process makes them the correct answer.
