What physical condition results in "Cow hocks" in rabbits?

The phenomenon known as "Cow hocks" in rabbits occurs when the hind legs turn inward at the hock joint. This condition is a physical abnormality where the angle of the hocks deviates from the normal, leading to a characteristic alignment that resembles cows’ hocks, hence the name. This misalignment can affect the rabbit's posture and movement, potentially impacting its ability to hop effectively and causing discomfort.

In contrast, while other options mention different issues, they do not specifically define the physical condition relating to the inward turn of the hocks. The inability to hop correctly relates to functional challenges that could arise from various factors, but this does not directly explain the anatomical feature of cow hocks. Overgrown nails may cause foot problems but are unrelated to the hock alignment, just as a genetic predisposition pertains to disease rather than an observable physical characteristic like cow hocks. Understanding this specific condition is important for proper care and breeding practices in rabbits.
