Trends in the number of dogs entering and departing Taiwan public shelters are analyzed in this article. There were 40 public shelters surveyed from 2000 to 2005 for dog entries and departures. The results indicate that (a) adoption rates and relinquished animal numbers increased, and euthanasia rates decreased at the beginning of the study, but they are showing signs of reversal; (b) shelters in cities have higher adoption rates than those in rural areas; (c) euthanasia remains the main means of controlling dog numbers in most shelters; and (d) potential adopters in Taiwan prioritize animal health and body size when selecting dogs for adoption. There is a need for increased and persistent public education to ensure continued progress is made in encouraging people to treat companion animals responsibly. In addition to educational efforts, creating new, specialized shelters for housing highly adoptable animals can alleviate the space constraint problems in existing kennels and improve the welfare of stray dogs.
