I love these and can relate to most of them!
I love his pricked ears. In the evening when I walk him and I see our shadows, I love to see his pointy-eared one
I also love how his ears are part of his body language. I can tell how he feels at every moment.
I also love the "state-of-the-mama-check" he gives me every morning. He has been doing this since he was a tiny puppy. When I go get him to take him outside, he *must* give me a quick sniff to make sure I am OK before he will let my put on his collar
eta: The one time when I approached him when I was sick with a high fever, he sniffed me and looked so dismayed that I thought I must be seriously ill. Turns out he was right.
