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.
