I remembered a scene from this movie last night and I've been searching for it on the internet all day but I can't find anything... It's killing me... The only scene I remember from this movie is a orange (I think) dog in like a hole in some kind of mountain... the dog is hiding here because it's raining and he's very sad but I don't remember why, I think he was crying... On top of that mountain there's a road and there's also a sad song playing in the background... I realize it's REALLY vague but that's all I've got...

PLEASE HELP ME! Thank you.

The only animated dog movie I can think of is Fox and the Hound. Hope that helps.
