Our Recommendation

Diamond Brand has a lot going on for it when it comes to producing quality dog food at a price that honestly at times makes me wonder how they do it. This is good stuff but the large breed puppy formula is a bit hit or miss. I don’t say this to blame the food but rather to highlight the concept of a low-calorie slow growth dog food. Big dogs want to eat a lot and when they want.

The thought behind a large breed puppy food is that it provides the nutrition needed for controlled growth. This concept goes against the natural order in a puppy’s brain. The result can be a puppy that is simply not as enthusiastic about this formula as you would expect.

Dogs are naturally attracted to foods that are higher in calories and flavor. This can be very apparent when you are trying to feed this formula to a puppy while also feeding the adult dog version to your older dog. The puppy will go for the adult version since it has more calories.

Also, there is the added appeal of the other dog eating it so they want it too! This puppy food will help control growth. Some pet parents give up on it simply because their puppy gets a bit stubborn.

Lamb-Based Means Grass-Based Proteins

What I like about this dog food is that it is lamb based. For those of you unfamiliar with the common farming practices in the United States, lamb is mostly grass fed and is a better quality meat than traditionally raised beef and chicken. This can also mean that you are exposing your pets less to GMOs that are found in a lot of the corn, wheat, and soy that is used to grow a lot of the animals produced under commercial agriculture conditions.

Diamond always makes sure to include probiotics in their dog foods which is something any pet parent can appreciate. Fish meal and flax seed oil are important sources of Omega-3 Fatty Acids and can help improve the coat and skin of dogs that are susceptible to skin allergies.

This is truly a dog food that offers a balanced diet of good quality proteins, veggies, and whole grains while also adding in probiotics that help your dog get the most out of their meals without any gastrointestinal distress.

So, you may want to consider what food you’re going to graduate your pup onto next. The Iams Adult Large Breed High Protein Dry Dog Food is a great choice for just that.

Nutro is a brand that’s well-known for their Feed Clean policy. They want you to feel confident in what you’re feeding your pet and therefore all their ingredients are non-GMO and they’re all recognizable ingredients, not something from a science lab. The very first ingredient is chicken, providing all the protein your large breed needs to keep growing and keep those muscles healthy. 

There’s a good amount of glucosamine and chondroitin from the chicken meal (the fifth most prevalent ingredient in this food) which promotes healthy joints, so important in large breed dogs old and young. There are thousands of positive reviews for this Nutro dog food, some even from qualified vets who love this dog food and choose it for their own pets! 

Let’s take a look at the pros and cons of Nutro’s Large Breed Dry Dog Food.


  • Chicken is the number one ingredient
  • Uses only non-GMO ingredients
  • Developed to keep your pup trim & fit
  • Natural sources of glucosamine and chondroitin for healthy joints
  • Antioxidants for a healthy immune system
  • Produced in the USA
  • Large breed and large breed senior options
  • Thousands of positive reviews


  • Developed to keep dogs trim and fit so probably not ideal if you need your pup to gain weight
  • Slightly more expensive than other brands

Nutro Natural Choice Large Breed Adult & Senior Dry Dog Food, Chicken: The Bottom Line

Nutro is a renowned brand that is trusted when it comes to providing natural, healthy dog food that’s formulated specially to improve the wellbeing of our little sidekicks. This formula is great for large breed dogs thanks to the healthy joint and healthy immune system boosting ingredients. If you’re looking for a dog food that’ll take your large breed from adulthood into their senior years, Nutro has your back. 

The Bottom Line

If you need to limit the growth of your large breed puppy then you can’t go wrong with this formula, but don’t expect your puppy to go crazy about it. It definitely provides a very complete, quality diet, but let’s face it, no puppy wants their growth controlled even if it is for their own good!

Once your pup becomes an adult, you can explore other options from this brand in our Diamond Naturals dog food review page.

One thing that you can do to add flavor without a lot of calories is to use beef broth or reconstituted beef bouillon cube broth to add some appeal to the kibble. It is very important to limit a large breed dog’s growth to avoid lifelong joint and hip problems.

Some breeds have such high initial growth rates that they can gain 2 lbs per day in body weight during peak growth! I actually had a hard time believing this until I charted the growth of my male Great Pyrenees and saw that he gained 14 lbs in a mere week. You want to feed them good but you also want steady growth when possible so they do not outgrow their frame.
