The dog loses its mind every single time you walk in. Nobody else is that consistent about being glad you exist.

Consistency of welcome is rarer than affection itself. People are pleased to see you in proportion to their day, their mood and how long you have been gone, and that is normal. An animal that reacts identically every single time is running on something simpler: the plain fact of your existence is good news, with no conditions attached.

Let that land rather than laughing it off. Then consider who gets it from you. Reacting visibly when somebody walks in is a small thing that people notice far more than they ever mention.
