A scoping review was conducted to identify all globally published literature investigating population dynamics and control practices of companion animals. There were 7810 unique citations initially identified, 869 articles (450 primary research and 419 reviews) were confirmed relevant. Most articles were conducted in the United States (359; 41.3%) and the main focus was on control practices (697; 80.2%). Among primary research articles, 204 (45.3%) investigated reproduction control, identifying an opportunity for further knowledge synthesis efforts. A Cox proportional frailty hazard analysis was conducted to determine factors that affect dogs’ (n=8,325) time to adoption within the British Columbia Society for the Prevention of Cruelty for Animals’ shelter system, between January 2010 and July 2014. Results demonstrated surrender reason, age, where animal was obtained, coat colour, breed, human population density of shelter location and incoming year significantly influenced dogs’ time to adoption. Findings suggest areas for targeted adoption promotion by shelters.
