Not easy to fill the spaces of an old beloved dog, but most of them do a great job once you get to know them good enough..
The longnosed dogs are usually very clever and understanding, easy to teach, and faitful till the end! Like a shephard WITH a sense of orientation :)
This one I see is a true longnose.. him understanding french is just to give you an excuse to take him out travelling the world :)
A friend of mine spent $44k on flight for her dogs when she went to AK for races, and came home with ovarall profit after a month over there!
Wish you a lot of great years with your new mate :)
