As with other very deep-chested breeds, gastric dilatation volvulus (also known as bloat) is the most common serious health problem in the borzoi. This life-threatening condition is believed to be anatomical rather than strictly genetic in origin. One common recommendation in the past has been to raise the food bowl of the dog when it eats. However, studies have shown that this may actually increase the risk of bloat.Less common are cardiac problems including cardiomyopathy and cardiac arrhythmia disorders. A controversy exists as to the presence of progressive retinal atrophy in the breed. A condition identified as borzoi retinopathy is seen in some individuals, usually active dogs, which differs from progressive retinal atrophy in several ways. First, it is unilateral, and rarely seen in animals less than three years of age; second, a clear-cut pattern of inheritance has not been demonstrated; and finally, most affected individuals do not go blind.
