Hi A K-

You at least need to worry about it until a year old. Some choose to air on the side of caution and feed a large breed puppy formula until 18 months of age. For giant breeds you would feed them as a puppy longer.

You could feed Orijen Large Puppy until a year (or longer if you’d like) and then move to any of the other formulas in Orijen since they are all life stages (including the Adult Dog formula). It should be fairly easy switching within the same brand of food.
