In fact someone just asked this same question to her not too long ago. Heres the question and her answer:
“I have been told large breed puppy food can be bad for my dane puppy. People tell me to switch to adult food saying the puppy food is too high in protein.
Should I stick with diamond large breed puppy, or switch to the adult brand.
15 week’s. Male greatdane/stbernard mix.
Thank you!”
1. Protein intake is not the problem with Developmental Bone Diseases in large breed dogs …. so these “people” are about 20 yrs out of date.
2. Yes stick with a large breed puppy food because the problem is really Calcium intake and AAFCO has set the maximum at 1.8% Ca on a dry matter basis to help protect these growing dogs.
3. Adult brands actually contain too much calcium when you do the math correctly based on calorie intake, so that is not advisable until 12-15 months of age.
