A 4lb dog needs to ingest ~1800 IU/lb of body weight of cholecalciferol (the most common form of vitamin D3) in order to risk renal failure. 4 lbs x 1800 IU/lb = 7200 IU - far in excess of the 2000 IU Princess ingested. There's no need to induce emesis or treat in any manner.

(Please check if the vitamin D3 were calcipotriene instead. It's not likely but the toxic dose is less - ~ 730 IU/lb - still not a danger to Princess.)
