If dogs could give Valentine cards (or even wanted to) I would think this would be the kind they might choose. Of course, they could have an entirely different thought about this. But I can really see a Pembroke Welsh Corgi saying, "Hey, that's me. I look happy. I could tell my human roommate how I feel with this card." That would be a nice surprise. Or if you live with a Corgi you could be the sender. I think dogs do like Valentine cards.
