Which of the following symptoms is NOT commonly associated with VHD?

The correct choice indicates a symptom that is not typically linked with Viral Hemorrhagic Disease (VHD) in rabbits. Rabbits infected with VHD usually exhibit severe symptoms that significantly impact their well-being and behavior. Symptoms of VHD can include sudden collapse, lethargy, and incoordination, which are indicative of the severe effects of the virus on their health.

Behaving normally is not a symptom commonly associated with this disease. In fact, if a rabbit appears to be behaving normally, it is likely that they are not exhibiting the typical signs of VHD. The disease is known for its rapid onset and severe clinical manifestations, which is why observing lethargy or collapse can be critical indicators of infection. Thus, the choice pointing out normal behavior distinctly contrasts with the severe symptoms associated with VHD, making it the correct answer.
