Diamond Naturals vs Hill's Science Diet Large Breed: Ingredients and Nutritional Data

First and foremost, it's important to see how Diamond Naturals and Hill's Science Diet Large Breed compare when it comes to macronutrients: crude protein, fat, and fiber.

Protein Content

Protein is a vital component of a dog's food, and it serves several roles in your dog's body, including muscle development and tissue repair, as well as forming skin cells, growing hair, tendons, ligaments, and hormone production.

Diamond Naturals is considered a high-protein food, while Hill's Science Diet Large Breed isn't but don't make a decision based on that alone, let's see how these foods compare in more detail, based on their guaranteed analysis.

Crude Fiber2.5%4.0%
Moisture10.0%10.0%

As you could see, Diamond Naturals has a higher amount of crude protein than Hill's Science Diet Large Breed. Dry foods usually contain between 20% and 30% of protein, while wet foods contain between 5% and 8%.

A higher amount of protein that comes from high-quality, animal sources is usually better, but some studies also suggested that too much protein might also be harmful.

The bottom line?

Quality is much more important than quantity, so it's the perfect time to check the most abundant ingredients in Diamond Naturals and Hill's Science Diet Large Breed.

The first five ingredients in Diamond Naturals: Chicken, Chicken Meal, Whole Grain Brown Rice, Cracked Pearled Barley, and White Rice.

The first five ingredients in Hill's Science Diet Large Breed: Chicken, Cracked Pearled Barley, Whole Grain Wheat, Whole Grain Corn, and Whole Grain Sorghum.

Ingredients are listed in descending order of weight, so both Diamond Naturals and Hill's Science Diet Large Breed have meat as the first and most abundant ingredient which is a good thing.

Fat Content

Fats are essential macronutrients, and they provide energy and are important for the development and function of body cells, nerves, muscles, and body tissues.

In fact, fats are a more concentrated form of energy than proteins and carbohydrates. They provide 9 calories per gram, while the latter provides only 4 calories per gram.

If your dog is obese or prone to obesity, you should probably look for low-fat foods that contain less than 10% of fat.

So let's take a closer look:

Diamond Naturals contains 16.0% of fat, while Hill's Science Diet Large Breed 11.5%

Fat ContentDiamond NaturalsHill's Science Diet Large Breed
Crude Fat16.0%11.5%
Omega-3 Fatty Acids0.4%0.3%
Omega-6 Fatty Acids2.5%2.5%
Omega-6 To Omega-3 Ratio6.3:18.3:1

Another important thing to consider is Omega-3s and Omega-6s contents. These essential fatty acids can't be made by the dog, which means that they must be obtained from food.

These fatty acids reduce inflammation, prevent blood clotting, improve brain development, and play an important role in heart and joint health.

Most high-quality foods will provide enough Omega-3 and Omega-6 fatty acids, and the same goes with Diamond Naturals and Hill's Science Diet Large Breed so you don't need to worry too much.

But there's a catch.

The omega-6 to Omega-3 ratio is very important for a dog's health. There is no perfect ratio, but The National Research Council (NRC) recommends a ratio of 2.6:1 to 26:1 Omega-6 to Omega-3.

With ratios of 6.3:1 and 8.3:1 of Diamond Naturals and Hill's Science Diet Large Breed respectively, these foods fall into the NRC's recommended range.
