C-Section There are several reported instances of cesearean sections for Silken Windhounds. Most of these seem to result from a lack of muscle tone in the uterus, misplaced or displaced puppies (such as laying across the vaginal canal), and prolonged labor. As with all whelpings, it is best to be prepared with the necessary items well before hand and to have directions to the closest emergency facility. Although probably not needed, it is always best to be prepared.
Cryptorchidism Chryptorchidism (retained or undescended testicals) have been known to occur in Silkens but not in significant numbers. Some dogs have had an undescended testical drop when they are near the six months of age. It is best to neuture a dog that is chryptorchid to avoid additional health issues.
Heat Cycles First heat cycles have been reported as early as 9 months of age and as late as 4 years old. However, the majority seem to have their first cyle between their first and second years. The age at which a female has her first cycle has not been shown to have any effect on the health of the litter. Cycling is different for each individual Silken. Some cycle only once a year and one or two have been known to cycle every three months or four times per year. The average appears to be twice a year. The duration of heat cycles has been reported to be at its shortest two weeks and at its longest four weeks. The average is approximately twenty one days.
LOTUS (canine equivalent of fetal akinesia deformation sequence) Lotus is a rare condition characterized by intrauterine growth retardation (IUGR), congenital limb contractures, pulmonary hypoplasia, hydramnios and craniofacial abnormalities. There have been instances of lotus births within the Silken population. The ISWS and its members are working with Dr. Margret Casal, Associate Professor of Medical Genetics, University of Pennsylvania School of Veterminary Medicine to study the causation and eventual determination of a "lotus gene" test.
