Which of the following is not a common rabbit disease?

Parvovirus is primarily associated with dogs, causing severe gastrointestinal disease, and is not commonly recognized as a rabbit disease. In contrast, snuffles, wry neck, and coccidiosis are diseases that specifically affect rabbits.

Snuffles is a respiratory illness caused by the bacterium Pasteurella multocida, leading to symptoms such as sneezing and nasal discharge. Wry neck, also known as torticollis, can result from infections or injuries and affects the rabbit's ability to hold its head in a normal position. Coccidiosis is a parasitic infection caused by the protozoan Eimeria, which affects the intestinal tract of rabbits and can lead to serious health issues.

Thus, identifying parvovirus as not being a common rabbit disease correctly distinguishes it from the other options, which are well-known health concerns for rabbits.
