Q. My chihuahua has swelling on her throat. The swelling started this morning. It doesn't seem to bother her. It worries me. I'm not sure what's going on

A. This could be an allergic reaction, possibly an insect bite or a food allergy. if it swells too much and seem to be painful when touched, bring her to the vet n order to get an injection to reduce the swelling ad stop the allergic reaction.
If it's not getting any bigger and doesn't bother her, wait a couple days it should start going down.
