Scooter has consumed 0.05mg. Symptoms of Vitamin D toxicosis can be seen with doses as low as 0.1mg/kg, and a lethal dose in a mature dog can be as low as 2mg/kg. He is 7.72kg, so he has consumed 0.0065mg/kg. As you can see, that is under the dose needed for toxicity. Just make sure he does not eat any more! I hope this helps!

    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.

What happens when your dog eats 60 vitamins D3 5000
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,

Dog ate 3000iu vitamin d
Hello. The general rule I apply to possible Vit. D intoxication is a pet can safely handle up to 10000 IU per kg of body weight. That means your 6 pound dog is safe up to 27,000 IU ( which I do not recommend giving ). So you have nothing to worry about at this time. Thanks for using Boop by Petco.

Hello My dad ingested 2 gummy vitamin ds and the serving size is 2 gummies at 2000IU and I was wondering if I should be worried about her eating the vitamins that she ate and she is about 70lbs
The amount of Vitamin D ingested will likely not put a dog of her weight at risk of serious toxicity. Make sure the gummies do not contain xylitol. That would be more dangerous than the Vitamin D. If they contain xylitol,seek veterinary attention immediately. Xylitol is toxic to dogs. It may cause a dangerous drop in blood sugar levels. If the gummies do not have xylitol, the worst you may see is some minor stomach upset.

Hello, this morning my 20lb dog digested a vitamin d3, 5000iu tablet. Should I be concerned I tried to make him throw it up and he wouldn't. Im very concerned, he seems okay.
Hi there! As long as Buddy only ate one tablet, this dose would not be expected to cause any problems. The toxic dose of vitamin D3 in dogs is 100 mcg/kg or above. 5000 IU = 125 mcg, and Buddy weighs about 9 kg, which means he got a total dose of about 14 mcg/kg. This is well below the reported toxic dose, so it's very unlikely that this will be an issue :)

My dog ate Vitamin D 400 IU + Calcium 600 Mg Anout Two pills or more.
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.

my dog was just diagnosed with arthritis and the vet recommended fish oil vitamins. I gave him one about an hour ago and just saw that it also contains 1,000 iu of vitamin D. I read that too much vitamin D is very harmful for dogs will he be ok??? he
The amount that he ingested is not considered toxic. Calculated, he ingested approximately 0.025mg of vitamin D and toxic doses for this size of a dog would potentially start at 5mg. He will be absolutely fine! I would recommend fish oil products such as welactin or Krillex krill oil treats.

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.

Hello and thank you for contacting Boop by Petco. One vitamin d capsule will not cause any problems to your dog. There is no need to see emergency vet or make her vomit. Please, monitor her at home, there should not be any worrying signs related to the capsule ingestion.

Hi my sons 9 month old boxer bitch has eaten 6 or 7 of my fultium d3 800 unit capsules Should I be worried I'm looking after his dogs and don't no what to do.
I would recommend making the dog vomit. You can try hydrogen peroxide at home or take him to a vet for them to induce vomiting. Usually dogs will vomit if they ingested the pills in the last hour or two. Fultium is a vit D supplement. My concerns is that it might decrease the Calcium released by the body and interfere with the hyperparathyroid gland. If you cannot get her to vomit I would recommend taking her to a vet. It is very important to monitor her for eating,drinking, defecating and seizure activity. IF at any time she is acting abnormal or not herself I would highly recommend taking her to a vet.

My 19lb dog ate one "NAtureMade" brand multi prenatal vitamin + DHA. Is she going to be okay?? She didn't eat the coating, just liquid inside. She also gets a little salmon oil on her meals. Ingredients of pill in pic.
Since she only ate 1 pill, I would not be worried about toxicity. The doses in the vitamins for each of the components should not be harmful. You may see some GI signs such as poor appetite, vomiting or diarrhea, but should resolve. If symptoms continue, I would recommend taking her to your veterinarian.
