I think it's Swedish and not French. If were thinking of the same movie, it must be "My Life As A Dog". Both VHS and DVD are available, but the DVD (Fox/Lorber) version sucks! Buy the VHS and wait for a better DVD re-release.
Yeah, it's gotta be LE GRAND CHEMIN. I watched it on late, late TV about six years ago, so I don't remember much, but if it involves a rabbit rescue and children getting the runs after eating crabapples, you're on the right track. Bye.
