Shortlegs, or Courtepatte in French, is a male dog.
Shortlegs was, in the 1930's, a basset whom Spirou selected as his hound when he tried out hunting. Shortlegs clearly put much enthusiasm into the task, but the whole business took a turn for the worst due to Spirou's shotgun being an antique that exploded upon firing (injuring Shortlegs, which, one imagines, put a damper on his relationship with Sirou).
Behind the scenes
Shortlegs firs tappeared in the 1938 comic Spirou the Hunter, going on to make a brief appearance in the very next Spirou comic. Being a Spirou character, he does not belong to the Walt Disney Company, although Spirou is considered canon on this wiki.
