Hounds of Trouble (a wc and batman fic) (Slade Wilson/Dick Grayson)

Slade Wilson wasn't exactly sure how he ended up undercover as Neal Caffrey, but if he had to guess it had something to do with his inability to tell his husband no. The problem only continues now that his husband left his strays with him. 

Or Slade gets stuck with Dick's dogs and white-collar finds out.
