I heard that a dog dies in Elven Lied or whatever it's called. D:
Maybe Marley and Me. Or this one Korean movie where this dog lives with this boy, but then gets abused by this other guy, but then then near the end the boy almost gets drowned, and then he wakes up and hits the guy with this metal pole. Then the police came and arrested him. The sad part was in the end and near the beginning when both the sister of the boy and the dog died. D:
I've cried at every single Pokemon movie, the saddest of which has to be Lucario and the Mystery of Mew.
The one where Pikachu runs away :c Not sure if I cried but it was sad :c
Another sad movie I saw was the one about the dog and the pudding cups.(The prequel before all those movies. Treasure Buddies, Santa Buddies etc. )
