Pet's info: Dog | Boston Terrier | Male | unneutered | 25 lbs
Dog weighing 25 lbs consumed 300-350 IU of Vitamin D, 250mg Calcium and 100 mg of magnesium. Are these toxic levels? I'm most concerned about the Vitamin D and Calcium.

Vitamin D can be toxic at levels above 1800 IU per pound, so Baby will likely suffer no ill effects from 350IU of Vitamin D. The calcium and magnesium doses are also well below toxic doses. You may see a bit of GI upset which can be managed at home with a 12-24 hour fast followed by a bland diet until symptoms resolve.
