canine cyclic hematopoiesis
an abnormality of hematopoietic stem cells that results in detectable, cyclic fluctuations in numbers of circulating neutrophils. Affected dogs have an increased susceptibility to infections. The condition is inherited as an autosomal recessive in collies where it is occurs with a distinctive silver-gray coat color; called also gray collie syndrome.
