What is a recommended preventive measure for rabbits that is related to VHD?

Vaccinating is a recommended preventive measure for rabbits against Viral Hemorrhagic Disease (VHD), a highly contagious and often fatal disease affecting rabbits. Vaccination plays a critical role in protecting rabbits from this virus, as it helps to enhance their immune system and prepare it to fight off potential infections. By ensuring that rabbits are vaccinated, owners can significantly reduce the risk of an outbreak in their population.

The other options do not offer effective prevention against VHD. Releasing rabbits outdoors can expose them to various infectious agents and increases the risk of contacting the disease. Providing unlimited treats might not only lead to health issues like obesity but does nothing to protect rabbits from VHD. Similarly, restricting movement may limit a rabbit's quality of life and does not address the root cause of disease prevention. Vaccination remains the most effective proactive measure to safeguard the health of rabbits against VHD.
