Is it okay to feed dogs eggshells?

Unless finely ground into powder no eggshell is very sharp and could cUt it internally

Only if you have a specific reason for doing it. You are adding a large amount of CALCIUM to the dog's diet, with egg shells. Unless you are feeding a diet that has NO calcium, or lacks enough calcium, you should not ADD it, without a sound reason and in the CORRECT amount - you will not be helping your dog.

No, eggshells can cause allergies to them.

No. If you mistakenly give them a very small piece by accident, they will be okay. But dogs just like people, should not eat egg shells!

you grind them up into a fine powder, added to the dogs food he gets calcium.

Why would you want to? If you feed it properly there is no need to feed it anything else.
