Hi sheeklouch –
Orijen is a wonderful food (it’s actually the best dry food out there – imo), however (unfortunately) none of their formulas are appropriate for large breed puppies – they are all much too high in calcium. For this reason, I’ve never fed Orijen to any of my pups but I have fed it to my adult with great success.
Gertie my now two year old female ate The Honest Kitchen (Zeal, Love, Thrive) and Tripett until she was 8 months old. Mabel, my newest addition, who just turned 7 months old has been on a controlled calcium homemade raw diet since she came to me at 8 weeks (my other two dogs eat raw now as well).
I think that most dogs do well on high protein foods (Gertie and Mabel both ate >40% protein on average) – if your dog is having loose stools with high protein foods I’d suggest trying a spoonful of plain canned pumpkin, a multi-strain probiotic and digestive enzymes at each meal.
Assuming you want to stick with a dry food, here is a list of recommended foods. Sometimes it’s trial and error and you may need to try a few foods before you find on that works for your dog. Some dogs are just more sensitive than others.
