What's the cutest thing your pet has ever done?

I have to go in depth to explain it so I hope you don't mind, you see, she had to get her uterus taking out, " she's a dog " cuz it was really infected, and like, she was in alot of pain after she got home from the vet, from the surgery yanno, my mom told me, that all she was doing all day while I was at work was laying in one spot whimpering, so that night, I let her sleep with me, me and her always had a close bond, basically I'm her favorite human lol, and she's mine, but anyways, I had her all cuddled up to me, and the only way I could get her to sleep was singing to her, and I did for hours, when I stopped though, she woke up looked at me and licked my nose lmao 😅 licking is something that's very unusual for her, not something she does too often, but I think it was just her way to tell me how much she loved me lol melted my heart
