Is it okay for dogs to eat human calcium tablets?

It is not advisable to give dogs human calcium tablets, because a dog’s digestive system differs from a human’s. Human calcium tablets may be hard for a dog to digest and can even irritate the stomach and intestines, causing diarrhea or vomiting. In general, dogs get enough calcium from their food, so unless a vet recommends it, human calcium supplements should not be fed. If a dog eats too many calcium tablets, it may develop digestive problems, bone diseases, kidney issues, and other health problems. If you suspect your dog is calcium deficient, have it checked at a veterinary clinic and supplement calcium under the vet’s guidance.
