As there are few requirements for mandatory registration or reporting for humane animal organizations, it is difficult to quantify how many dogs enter such organizations annually, or know their outcomes. Our objectives were to quantify the number of dogs entering animal shelters in five states in 2017, and determine factors that influenced their outcomes. A census was conducted of shelters in five states from each geographical region of the US. Organizations were excluded if they transferred all dog, or were breed-specific, foster-based, or functioned solely as a sanctuary with no options for adoption. Shelter employees were questioned in face-to-face interviews about specific shelter characteristics, the number of dogs that entered their shelter in 2017, and their outcomes. In total 342 of the 471 (73%) shelters in the final sampling frame reported receiving 227,783 dogs in 2017. Of these, 45% were adopted, 18% were transferred other facilities, 19% were reclaimed, and 14% were euthanized. Shelter characteristics influencing dog outcomes included financial source, source of dogs, county population per square mile, and education level of the county.
