We just got a Great Dane pup, he's about 14 weeks old now.  He's suppossed to be on the larger side when full grown so we've been looking for elevated feeders.  I wanted one like the Pet Zone feed-n-store but their tallest feeder is only 12" high, he's already outgrown that size. Is there a giant breed feed and store or at least an elevated food and water bowl taller than 18"  That seems to be the tallest I could find anywhere. Please help. Is the feeder suppossed to be at chest/shoulder height to the Dane?

Also, on the protein issue. He has little bouts of soft stool, bordering on diarrhea. We have given him cottage cheese and canned pumpkin to help this.  The pumpkin is protein free but the cottage cheese isn't.  Is that bad?
We don't see the vet for another week.

Thanks for the help.
