Kirkland Nature’s Domain Review
Kirkland Signature Nature’s Domain Dog Food is produced by Diamond Pet Foods, a reputable company with a strong track record in pet nutrition. Available at Costco stores, including in Australia, it’s praised for delivering premium-like quality at a fraction of the cost. Taste of the Wild shares the same factory, which speaks to consistent manufacturing standards.
The star of this formula is salmon, listed first, followed by salmon meal. This dual-protein punch ensures high bioavailability, supporting muscle maintenance, energy, and coat health—key for active dogs. Unlike many budget foods starting with grains or fillers, this prioritizes meat, aligning with canine dietary needs backed by veterinary nutritionists.
That said, the next ingredients—sweet potatoes, potatoes, and peas—shift toward carbs for energy and fiber. Sweet potatoes shine here as a low-glycemic source of vitamins A and C, antioxidants, and digestible fiber, promoting steady blood sugar and gut health. Potatoes add bulk, while peas contribute plant-based protein and minerals. These aren’t ideal as top ingredients but are far superior to corn or wheat in comparable price-range foods.
Supporting nutrients like flaxseed (omega-3s for skin and joints), salmon oil (DHA/EPA for brain and heart health), and probiotics round out the profile. Overall, this earns a solid 7.5/10 rating: decent for everyday feeding, especially for cost-conscious owners.
