Generally greyhounds are a very healthy breed as they have been bred for their physical strengths. Some common (though still rare) afflictions that affect greyhounds include an eye condition called pannus and a disease of the nails called SLO. Being large-breed dogs they are also more prone to osteosarcomas and bloat (gastric dilatation and volvulus). Greyhounds who have raced may also be more prone to arthritis.
