I found this text and others that say giving extra calcium is not a good idea.
NOTE: Supplementing a pup's diet with extra calcium in the hope that it will "build up" the ear cartilage is not scientifically or biochemically valid. Adding additional calcium above the usual balance of that mineral with phosphorus and Vitamin D has actually been shown to cause growth problems in dogs. Don't add calcium to a dog's diet in the misguided hope that it will "strengthen the cartilage". |
