Abstract
We have treated injured and/or diseased wild animals which were brought in to the Animal Clinical Research Foundation Hospital from the western and central parts of Tottori Prefecture. Among them we studied wild racoon dogs treated during 2000-2009. Many of them happened to be involved in a traffic accident, and were carried to us with bone fractures or injuries, and some of them were also suffering from infection with Sarcoptes scabiei. Since 2003, there were 14 raccoon dogs with sarcoptic mange, and the number of infected animals was highest in late spring and from autumn to winter although the total number of the racoon dogs which were brought to us was highest in March and September. The numerical changes in sarcoptic-mange- infected racoon dogs in a relevant institution in Gifu Prefecture were similar to ours until 2008.
