Does Costco Only Carry Kirkland Signature Dog Food?

Believe it or not — no! While Kirkland Signature is Costco’s exclusive brand and is known for its high-quality dog food, Costco also carries the Blue Buffalo dog food brand in-store.

Kirkland Signature dog food comes in both dry and wet forms for dogs of all ages and weights. It is available online at Costco.com in addition to store locations throughout the U.S. Keep in mind that Kirkland Signature dog food can only be bought at Costco. You won’t be able to find this brand at any other pet store. 

On the other hand, Blue Buffalo is a widely known dog food brand that can be found at other pet supply and grocery stores throughout the country. You’ll only be able to find this brand in person at Costco stores as it is not currently available online. If you see Blue Buffalo bags at your local Costco, the benefit to buying this dog food is that it is available in bulk for less than other retail stores. They often sell adult dog food at Costco. 

Is Kirkland Signature Dog Food Good?

Every dog parent has their favorite food brands, and if you’re worried about choosing Kirkland Signature, let me ease your mind. While store-brand pet food is usually low-quality and cheap, Kirkland Signature is the exception. It’s extremely high-quality while still being affordable, and has fresh ingredients like fresh protein and vegetables. It’s also filled to the brim with nutrients like omega fatty acids and vitamins. 

While Kirkland Signature dog food is made for Costco to be sold only at Costco stores, the pet food is actually produced and manufactured by Diamond Pet Foods, Inc., which is one of the biggest names in pet food. They make popular brands like Taste of the Wild and Solid Gold, so you know it’s great quality. 

Kirkland Signature also has the perfect variety of dog food. They offer dry and canned food with several different proteins and age ranges. There are two kinds within the brand, Super Premium and Nature’s Domain. Super Premium is more of the basic selection with the main ingredient primarily being chicken with vegetables. Nature’s Domain expands its protein list to lamb, turkey, and salmon and focuses on being grain-free. Both sides come in formulas made for puppies, smaller breeds, and adults.

Every dog has their own unique tastebuds, so I can’t promise that your dog will like the first pet food that you buy. But once you find the right flavor combination, your pup will surely be in love as they’ll get the right nutrients they need to stay healthy and happy, all while eating delicious, high-quality, and fresh protein and produce.
