  • Protein Source

Adult dogs need 18% – 25% protein in their dietary calories. That’s why protein is an essential ingredient in dog food. For its ingredients, Kirkland Dog Food sticks to the basic. Most of their recipes use traditional ingredients. They use common meats like chicken, turkey, and beef. Even the vegetables they include are traditional, such as peas and sweet potatoes. Blue Buffalo offers less traditional recipes. They have a wide selection of recipes: turkey to bison, and salmon to trout. Due to this variety of meats, Blue Buffalo products tend to contain more proteins. In fact, one of Blue Buffalo products is a great dog food to gain weight and muscle. Take a look at the details below!

Blue Buffalo Life Protection Formula w/ Lamb & Brown Rice Recipe

Lamb and brown rice recipe this product offers comes in real meat as its main source of protein. Not just real, but these are farm-raised lamb, ensuring its taste and quality. Besides the brown rice, they use Barley and Oatmeal that are wholesome whole grains. For extra nutrition, Blue Buffalo Life Protection Formula has sweet potatoes in it.

That’s where your dog will get their intake of carbs and fibers, which help their digestion a lot. What we love is that it contains Omega 3 and 6. These fatty acids help maintain your dog’s shiny coat. Like most Blue Buffalo products, this one also contains Lifesource Bits. However, please note that we only recommend this for adult dogs and those who don’t have any problems with consuming grains (not grain sensitive). There are no artificial additives added, as well as no flavoring and preservatives. Everything is natural and your pooch will love it!

  • Carbs Source

Yes, your dog still needs carbs. Kirkland Dog Food uses whole grain brown rice, ground white rice, and rice brand. Blue Buffalo uses fresh potatoes to provide carbs that are easier to digest. Other than potatoes, they also use barley and oat flour. If you are unsure whether grains and rice are good for your dogs, you can go for their grain-free lines. Kirkland with their Nature’s Domain lines have you covered. 7 of 8 Blue Buffalo lines are also available in grain-free options. Usually, the source of the carbs in grain-free products is from potatoes. Potatoes are the superior carbs alternative to grains. This way, you can still provide your dog with the carbs they need without worrying.

  • Exclusive Ingredient

Other than additional nutrients, Blue Buffalo features LifeSource Bits. It’s a precise blend of vitamins, minerals, and antioxidants. Veterinarians and animal nutritionists selected the ingredients that made up LifeSource Bits. They use the technology that allows them to “cold-form” the bits. This is to minimize the heat exposure that may degrade the potency of many vitamins, minerals, antioxidants, and enzymes. You will find them in the form of small, dark kibbles mixed in with the dog food.

  • Product Variety

Kirkland Dog Food has two lines: Kirkland Signature and Kirkland Signature Nature’s Domain. Kirkland Signature Nature’s Domain is the grain-free variety. Both lines are available in the form of dry food, canned food, and dog treats. Blue Buffalo has 8 product lines with up to 101 options available! Each lineup has different recipes for different ages.
