Bilateral cataracts in a coyote (Canis latrans) pup from Saskatchewan, Canada

A free-ranging coyote (Canis latrans) pup was found in rural Saskatchewan and was subsequently presented to a veterinary teaching hospital by a wildlife rehabilitator. On physical examination, the pup was found to be blind as a result of bilateral, mature cataracts, which were confirmed on postmortem examination. No other significant intraocular or extraocular disease was detected, resulting in a presumptive diagnosis of congenital cataract. To the authors' knowledge, this is the first report of congenital cataract in any wild canid species.
