Does my 9-month-old GSD puppy need calcium supplements or eggshells?

A fully balanced diet such as large breed food formulated for the age of your dog (puppy or adult) would not need to be supplemented with any calcium supplement and indeed over supplementation can also cause problems. I suggest you speak to your local food suppliers to suggest a suitable, balanced diet in order to ensure all his needs are being met, not just calcium and phosphorous

Thanks for using Petco Pet Education Center, formerly Petcoach! I recommend feeding Rocky a good dry puppy food (like Science Diet, Purina One, Iams, or Royal Canin). If you do that, eggs won’t be necessary. If you still want to add an egg I would only give one a day. Kisses to Rocky!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Bone is SUPER cute!! I do not recommend calcium supplementation. Once Bone is 5-6 weeks old start feeding him a commercial puppy food, like Purina puppy chow. If you are bottle feeding him with a puppy formula you can start mixing that with puppy food now. All commercial puppy foods are nutritionally balance. Over supplementing calcium can cause harm. I hope this helps!

No, I would not give Milo multi-vitamins of calcium supplements. While puppies do need higher amounts of protein, calcium, and calories than adult dogs, their puppy formulated food will provide that for him. It's never recommend to give puppies multivitamins and extra calcium as that can have detrimental effects on their growth, especially excess calcium. Stop giving Milo this supplements now, and be sure to feed him a high quality large breed puppy formulated food such as Royal Canin.

Royal Canin is a complete, balanced food. It should not be necessary to add other supplements. Adding additional calcium or vitamins could actually be detrimental as it will throw off normal ratios. Thank you for using Petco Pet Education Center, formerly Petcoach

A balanced puppy food which has been specially formulated to be a complete diet should not be supplemented as this can lead to dietary excess, which can also be harmful to bone development. Check that the puppy food is suitable for the age and breed type and if you have concerns about bone and joint development I recommend a full physical by your vet to determine which, if any, supplementation is required

Puppies should never get multivitamins. They don't need it, and you run the risk of overdosing them on certain vitamins. As long as Koda is getting a puppy formulated food, he is getting all the vitamins he needs.
