leave it在這里的意思的“放著不要動”，“不準(zhǔn)動它”的意思，用作祈使句有命令的意味

狗狗科普：

The outer coat is sleek and water repellent, and lies flat against the body. The official colour of the breed is the varying shades of gold that are most often seen.?The breed's intelligence and versatility suit the dogs well for a variety of roles including guide dog for the blind, hearing dog for deaf people, hunting dog, illegal drug detector, and search and rescue participant.
