Kirkland Signature pet food is a brand that is owned by Costco, which is a wholesale retail and grocery store. Kirkland is advertised as being a healthy dog food brand, and many of its bestselling products are those that are organic and grain free. However, they have a wide variety of dog foods and dog treats available.

In addition to pet products, Kirkland Signature also produces many other products for Costco. These products include but are not limited to food products for humans, health and beauty products, and products for babies. Like with their dog food, Kirkland advertises these products as being quality buys for a low price.

Costco is known for its large big box retail stores that require a membership to shop. Many of their items are sold at whole sale, which is usually sold at a reduced price when compared to other large stores like Walmart or Target. Costco was founded in 1983 and they currently have around 804 warehouses world wide.

Even though Kirkland Signature is a Costco brand, this dog food is actually manufactured in the same plants that produce Diamond pet foods. Diamond pet foods is another dog food brand that is commonly sold in pet stores.

Kirkland Dog Food History

kirkland dog food history

The Kirkland Signature brand was created by Costco in 1995. However, over time the Kirkland Signature products have improved in quality while still remaining affordable. This is mainly thanks to the brand being popular among consumers and gaining reputability over the years.

Thanks to this improvement in quality, Kirkland dog food is actually made by diamond pet foods. This is generally regarded as a high quality dog food brand that can be high in price depending on where you purchase their products from. Diamond pet foods were created in 1970.

Considering that Diamond produces Kirkland pet food, they are of generally the same quality. However, Kirkland dog food is usually cheaper in price than Diamond pet food is.

Where Is Kirkland Dog Food Made?

Kirkland dog food is made from the same plants that Diamond dog food is made from. Currently Diamond produces their dog food in five different plants that are located in four different states within the United States. These locations include Missouri, California, South Carolina, and Arkansas. Of course, Kirkland dog food is made in these locations alongside Diamond dog food.

Many dog owners are put at ease when they find out that Kirkland dog food is made within the United States. This is because most of the time pet foods made within the United States are of a higher quality than those that are not, which is mainly thanks to food production laws within the United States.

Kirkland Dog Food Ingredient Quality

In all of Kirkland’s dog foods, the first ingredient is either fresh meat or a meat meal. For example, in the adult formulas, the first ingredient is either fresh chicken or fresh lamb. However, in Kirkland’s Nature domain line the first ingredient is a meat meal. Meat meals are essentially ground up meat that includes a wide variety of cuts. Meat meal types that are included in Kirkland dog food include:

  • turkey meal
  • salmon meal and other kinds of fish meal
  • beef meal
  • chicken meal

The next ingredient in Kirkland dry dog food is either sweet potato or whole grain brown rice. These are both widely considered to be healthy and high quality dog food fillers. The only difference is that sweet potato is used it replace whole grain brown rice in Kirkland’s grain free dog food products.

There are some other ingredients that are commonly used in Kirkland dog food besides things like chicken meal and whole grain brown rice. Some of these other ingredients include:

  • peas
  • potatoes
  • organic canola oil
  • salmon oil
  • tomato pomace
  • flaxseed
  • tomatoes
  • blueberries
  • raspberries
  • dried chicory root
  • dried egg product
  • carrots
  • cracked pearl barley
  • chicken fat
  • dried beet pulp
  • brewers dried yeast
  • dried kelp
  • apples
  • cranberries
  • natural flavor
  • yucca schidegira extract
  • salt
  • rosemary extract
  • parsley flakes
  • millet

Even though every one of these ingredients may not be included in every one of Kirkland’s dog foods, they are frequently included in their products. Generally speaking, the only potentially controversial ingredients that are included in Kirkland dog food is organic canola oil, tomato pomace, dried beet pulp, and brewers’ dried yeast.

These ingredients are mainly considered to be controversial because they are cheap dog food fillers with little nutritional value to dogs. In some cases, an ingredient may be considered to be controversial simply because there is a healthier alternative to it. A good example of this is canola oil, and this is because other oils are considered to be healthier sources of omega 3 fatty acids.

The good news is that Kirkland dog food lacks many other controversial ingredients that are commonly included in other dog foods. Things like pea protein, high fructose corn syrup, and corn meal. Rather, Kirkland mainly includes ingredients that will provide dogs with healthy nutrients.

In addition to whole ingredients, Kirkland also enriches their dog foods with vitamins and minerals that are essential to a dog’s diet. Here is a list of all the healthy vitamins and minerals that are included in Kirkland dog food formulas.

  • vitamin e supplement
  • choline chloride
  • iron proteinate
  • zinc proteinate
  • copper proteinate
  • ferrous sulfate
  • zinc sulfate
  • copper sulfate
  • potassium iodide
  • Vitamin B1
  • manganese proteinate
  • ascorbic acid
  • vitamin A supplement
  • biotin
  • niacin
  • calcium pantothenate
  • manganese sulfate
  • sodium selenite
  • vitamin B6
  • vitamin B12 supplement
  • vitamin B2
  • vitamin D supplement
  • folic acid

The only potentially controversial item on this list is sodium selenite. This is because sodium selenite is not considered to be as nutritious to dogs as selenium yeast. Not only is selenium yeast a better source of selenium than sodium selenite, but it is more natural as well.

Additionally, Kirkland also includes several different types of probiotics in their dog foods. Many high quality pet food brands will include probiotics in their products because it aids in the digestion of the food. Some of the exact probiotics that are commonly included in Kirkland dog food include:

  • dried Lactobacillus acidophilus fermentation product
  • dried Bifidobacterium animalis fermentation product
  • dried Lactobacillus reuteri fermentation product

When looking at these ingredients and comparing them to those that are included in some other dog food brands out there, you come to realize that this dog food is actually of pretty good quality. As a result, many Kirkland dog food reviews are positive, and dogs can receive a healthy diet when eating Kirkland dog food.

In addition to this, Kirkland Signature dog food is also reported to be easy dog food for dogs to digest. This is mainly thanks to the fiber and probiotics that are included in Kirkland’s dog food recipes.
