Comparing Ingredients
When it comes to ingredients, Orijen clearly contains more premium protein sources. The first five ingredients are all fresh or raw meats, compared to just one fresh meat in the Iams food.
Iams relies more on plant-based proteins like corn and soy. Orijen takes the ancestral approach, mimicking the whole prey diet a puppy’s ancestors would have consumed. This includes muscle meat, organs, and bones.
As far as carbohydrates, Iams contains grains while Orijen utilizes fruits, vegetables and legumes instead. This gives Orijen the edge for dogs that may have sensitivities to grains.
Based on ingredients alone, Orijen puppy food is the superior option. But ingredients don’t tell the whole story…next up is pricing and affordability.
Price and Affordability
When it comes to price, Iams has a significant advantage over Orijen. You can purchase over 3 times as much Iams puppy food for the same price as Orijen.
This drastic price difference reflects the contrast in ingredients. Orijen utilizes far more premium protein ingredients—which come at a higher cost.
Iams makes an affordable puppy food while still providing good nutritional value. But for pet owners willing to invest more for quality, Orijen is worth the higher price tag.
So which food provides the best value? That depends on your budget and priorities…
Best Value Puppy Food
For pet owners wanting an affordable, nutrition-packed puppy food from a trusted brand, Iams Proactive Health Smart Puppy offers outstanding value.
You can feed an Iams-based diet for a fraction of the cost of many competitor brands (like Orijen). This doesn’t mean Orijen isn’t a good choice though…it just costs more.
Orijen is one of the priciest puppy foods on the market—but it’s not overpriced. When you factor in the outstanding ingredient quality and nutritional standards, Orijen delivers exceptional value at its premium price point.
So if your #1 priority is an affordable yet nutritious food from a reputable brand, Iams puppy food is the best value pick. But if you want the very highest quality ingredients and are willing to pay more, then Orijen offers standout value for a premium food.
Puppy Food for Large Breeds
One area Iams puppy food has an advantage is with its specialized large breed formula.
Iams Proactive Health Smart Puppy food is specifically tailored to meet the needs of large breed puppies during the crucial developmental stage. This includes optimal protein, fat and calcium levels to support controlled bone growth.
Orijen is an excellent all-life stages food, but doesn’t offer breed-specific formulas. For giant and large breed owners wanting a tailored nutrition solution for their pup, Iams is an ideal pick.
Best Puppy Food for Large Breeds
If your priority is finding the best puppy food specifically geared for large breeds, Iams Proactive Health Smart Puppy is an excellent choice. From appropriate protein levels to the right calcium content, this formula helps set up big pups for long-term musculoskeletal health.
For owners of small or medium-sized breeds, both Iams and Orijen offer terrific nutritional profiles. So the choice comes down to budget and preferences around ingredients and processing.
The Verdict: Iams vs. Orijen Puppy Food
When choosing between Iams vs. Orijen puppy foods, there’s no universally “best” option. Iams offers outstanding quality and value, while Orijen utilizes superior ingredients.
