Extremely cute!
This was in Spanish, but it was great how someone who didn't speak Spanish could understand it. I really like how you only use silhouettes. Some people might look at that and be critical as it could be a lack of detail, but I think it really adds to the feel. I did kind of think it was weird how he left in 1945 as that was the end of the war, but whatever. Stories about people and their dogs come across as heartwarming to me. You didn't use dialogue, you just used standard action tell a great story.
