  This would be 0.05mg of vitamin D. Louie would need to eat 0.1 mg/kg in order to cause toxicity. This is not enough to cause any problems, but be sure he does not get into any more! I hope this helps.

  A one-time dose of Vitamin D of 800IU + should not really be a problem as the normal daily dose is 227 IU/lb of food consumed on a dry matter basis and a toxic dose gtiven over months would be 2272 IU /lb food consumed on a dry matter basis. So even a high one-time dose of Vitamin D plus Calcium should not cause any toxic signs or damage.

  Unless you have a very large dog, this could be a serious problem. You should seek veterinary attention as vitamin D poisoning can be life threatening. Consider the following:
  
  5,000 IU of vitamin D = 0.125mg. Your dog ingested 60. 0.125mg x 60 = 7.5mg of vitamin D. Veterinary attention is indicated when more than 0.1mg/kg of Vitamin D is ingested. Life threatening effects are possible at 0.5mg/kg. Divide 7.5 by your dog's weight in kg, to determine the dose ingested. Even if you have a 100lb dog, he/she may be in serious danger,

  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.
