Question

what do you call a person who takes their person everywhere even when it's unnecessary

Answer 1

A person who takes their pet everywhere, even when it's unnecessary, is sometimes humorously referred to as a "pet parent" or "overzealous pet owner." If the context is more about the behavior itself, you might describe them as "overprotective" or "overindulgent" with their pet. In a more informal or humorous sense, some might call them a "crazy cat/dog person."
