Black Lab found in LaSalle

I found this old Black Lab on the street of McVey, Lasalle, Qc, Canada. On the 19/05/14 at 10:30pm. She looks around 7-8 years old, well tempered and loves everyone and other dogs. She limps, it seems her leg is either hurt or sprained. She has not tags but she was wearing a collar. For now we have been calling her “Black beauty” but “Black” for short.
