It would help to know what specific kind of tablets they were, how much calcium each one contains and how many she ate, as well as how much your dog weighs to give a more specific answer. But in general, I can tell you that a one-time overdose of calcium tablets like Tums or calcium-containing vitamins is usually not a major problem - calcium in this form is poorly absorbed from the GI tract, so most dogs have to eat a truly massive amount of cause any toxicity issues. You may see some mild GI upset, but other problems are probably unlikely. But if you have any concerns, the safest bet is always to have your dog seen by a vet - if she ate them within the past couple of hours, the vet can induce vomiting to help make sure there won't be any problems.

Hello. Most calcium doses just result in a transient gastro-intestinal upset, but since you do not indicate how much calcium is in each tablet, it might be best to contact your veterinarian & have a CBC & serum chemistry analysis done. Better safe than sorry & have Storm develop any kidney problems. Thanks for using Petco Pet Education Center, formerly Petcoach.

My puppy ate a calcium and vitamin D3 pill. What should I do?

This is not a toxic dose for a 15 pound dog. That being said, it could still upset his stomach. He could show signs anytime in the next 48 hours. If he starts to seem sick you should take him to your vet ASAP. I suggest you feed him 1/2 a piece of bread that will help coat the tablet and pull it through his GI tract. No other food for 6 hours. Hope this helps. Best wishes.

My 19lb dog ate a human prenatal vitamin with DHA. Is she okay?

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.

My dog ate Vitamin D capsules. Should I be worried about toxicity?

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 dog ate a human gummy multivitamin. Should I be worried?

If it is a ''gummy'' tablet it may cause gastrointestinal signs such as vomiting or diarrhea. The toxicity from the single components (Vitamins, mineral etc etc) depends on their concentration. Generally speaking it should be a major concern as the concentration is quite low. If there is xylitol inside the tablet that may be dangerous, and in case of ingestion, your dog needs to be seen by a veterinarian. The ingestion of xylitol or xylitol-containing products causes a rapid release of the hormone insulin, causing a sudden decrease in the dog's blood glucose. Signs to look for are: lethargy, vomiting, loss of coordination, collapse, and eventually seizures.

Puppy ate vitamin C tablet: Will she be okay or get an upset stomach?

I'm surprised that Moxxi ate a Vitamin C tablet because they are usually very bitter. Vitamin C is a water soluble vitamin, so we don't need to worry about toxicity, but high levels of Vitamin C can irritate the stomach and cause diarrhea. I would be worried that Moxxi may develop some stomach upset from that level of Vitamin C. It would be worthwhile to contact your veterinarian if she starts vomiting or develops diarrhea. I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

My 20lb dog ate a 5000 IU vitamin D3 tablet. Will he be 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 folic acid tablets. Is it dangerous or will he be okay?

Studies have shown that ingestion of even very large doses have no adverse effects. However, there is some risk of obstruction or blockage of the intestinal tract from undigested capsules. If your maltese stops eating or begins vomiting, I recommend seeking veterinary attention to rule out an obstruction. Make sure he has access to plenty of water, and you may consider adding water to his food to help the capsules break down.
