As "worry" per se does not appear in this quantification, I'd propose that "distress", "fear" and "suspicion" could qualify as facets of worry.

"Worry" generally implies a concept of imagined future, which is arguably beyond what we normally associate with dog cognition (dognition?). I mean, as a feeling worry always has an object, explicit or implied. We worry about something happening or not happening, about a person or thing. Without an object, worry becomes just nervousness/fright/anxiety distress/fear/suspicion

Okay.
