Specially formulated for breeds weighing greater than 55 lbs as adults. Made with high quality chicken for great taste. No by-products, artificial colors, or flavors. Naturally preserved with Vitamin E. Highly digestible for better nutrition and less backyard clean-up. 100% complete and balanced.

I feed Large Breed Puppy for 2yrs and than Large Breed Adult.
All Large Breed foods are not the same
example:
Royal Canine Large Breed Pupppy - 30 to 32% protien
Authority Large Breed Puppy - 26 to 28% protien
I think the Royal Canine is too high for a growing pup, I feed the Authority for growing pups and Royal Canine & Authority with fresh cooked meat mixed for a pregnant mom.
