This study describes the occurrence of fibrocartilaginous embolism of the s
pinal cord (FCE) in eight juvenile Irish Wolfhounds that were presented wit
hin a period of 16 months (1996-1997). The dogs, seven males and one female
between eight and 13 weeks of age, were presented because of an acute onse
t of abnormal locomotion. Five dogs were euthanized and FCE was diagnosed b
y the histomorphological presence of focal myelomalacia and Alcian blue-pos
itive-nucleus-pulposus material in the spinal cord vasculature. Three dogs,
which were thought to have FCE because of their clinical symptoms, improve
d with partial or almost complete return to normal locomotion. Although the
observed high incidence may be a coincidence, oral information from breede
rs and lay reports of similar cases in journals for dog breeders from vario
us countries suggest that FCE is a common disorder in young Irish Wolfhound
s.
