In terms of housing, competing senior horses were most frequently kept in a stall but with \u226512\u2009h a day on pasture. Competing seniors were predominantly 15\u201320\u2009years of age (73.4%), were geldings (69.5%) and were Quarter Horses (33.5%). About one\u2010half competed\/trained for competition at a medium level. Three percent competed at the highest (e.g., international) level. The most common discipline was dressage (32.0%). Stiffness\/reduced leg\u2010joint flexibility was the most common owner\u2010reported clinical sign (29.2%; 95% CI: 23.5\u201335.6) and osteoarthritis was the most common owner\u2010reported veterinary\u2010diagnosed medical condition (32.6%; 95% CI: 26.8\u201339.0), followed by gastric ulcers (8.0%; 95% CI: 5.1\u201312.3) and lameness (7.6%; 95% CI: 4.8\u201311.8).
