Best Toppers for Kirkland (Costco) Dog Food (2026)
Kirkland (Costco) is a trusted value bulk-warehouse formula that many dogs thrive on—but even the best kibble can benefit from a quality topper. Whether your dog is a picky eater, needs more hydration, or simply deserves a flavor upgrade, the right topper makes a real difference.
Kirkland Signature dog food, made by Diamond Pet Foods, offers excellent value. A quality wet food or freeze-dried topper upgrades it significantly for picky eaters.
This guide covers the five best toppers for Kirkland (Costco), chosen for quality ingredients, palatability, and nutritional balance.
Why Add a Topper to Kirkland (Costco)?
Dry kibble is convenient and nutritionally complete, but it lacks the moisture and aroma of fresh food. Adding a topper delivers several benefits:
- Increased hydration: Dogs on dry-only diets often drink less water. Wet or broth toppers add significant moisture to every meal.
- Better palatability: Even great kibble can become boring. A topper rekindles interest in mealtime.
- Nutritional diversity: Whole-food toppers add enzymes, probiotics, and micronutrients not always present in processed kibble.
- Easier medication administration: A tasty topper makes hiding pills simple.

Detailed Reviews
1. The Honest Kitchen Daily Boosters Bone Broth
Best for: Hydration and picky eaters
Price: $14.99 | View on Amazon
The Honest Kitchen’s bone broth is a human-grade dehydrated topper made with real chicken and turmeric. You simply mix it with warm water and pour it over Kirkland (Costco) kibble. The result is a savory, aromatic broth that transforms a dry meal into something irresistible.
The turmeric adds natural anti-inflammatory properties, and the collagen content supports joint health—particularly valuable for large breeds and seniors eating Kirkland (Costco). Because it’s human-grade, you can trust every ingredient.
Pros: Human-grade, easy to prepare, great for hydration
Cons: Requires warm water prep; not ideal for households wanting a no-fuss option
2. Stella & Chewy’s Freeze-Dried Raw Dinner Dust
Best for: Maximum nutrition and raw feeding integration
Price: $19.99 | View on Amazon
Stella & Chewy’s Dinner Dust is one of the most popular toppers on the market for good reason. Made with 95% raw, cage-free chicken including organs and bone, it comes in a fine powder you simply sprinkle over Kirkland (Costco) dry food. No refrigeration required.
The raw nutrition—enzymes, probiotics, and bioavailable protein—complements Kirkland (Costco)’s cooked kibble by adding what the cooking process reduces. Dogs go absolutely wild for the smell and taste.
Pros: No prep, intense flavor, shelf-stable, raw nutrition
Cons: Premium price point; some dogs may be sensitive to rich organ ingredients
3. Purina Pro Plan Wet Dog Food Variety Pack
Best for: Seamless nutrition upgrade and picky eaters
Price: $22.49 | View on Amazon
A wet food mixer from the same high-quality stable as Purina Pro Plan kibble means you’re adding complementary, well-researched nutrition. The high moisture content (around 78%) dramatically boosts daily fluid intake, and the rich meaty texture makes every bowl more exciting.
For dogs already eating Kirkland (Costco) kibble from Purina or another brand, this is an easy, consistent addition that’s unlikely to cause digestive upset.
Pros: Vet-trusted brand, high moisture, easy transition
Cons: Opened cans must be refrigerated and used within 2–3 days
4. Open Farm Homestead Turkey & Chicken Bone Broth
Best for: Clean-label households and senior dogs
Price: $11.99 | View on Amazon
Open Farm’s bone broth is made with humanely sourced turkey and chicken with no added sodium—an important distinction since many store broths are dangerously high in salt for dogs. It pours directly over Kirkland (Costco) kibble for an instant moisture and flavor upgrade.
The collagen from slow-simmered bones supports joint health and gut lining integrity. Open Farm’s commitment to ethical sourcing and transparency makes this a premium pick for health-conscious pet owners.
Pros: No added sodium, humanely sourced, supports joints and gut
Cons: Refrigerate after opening; slightly higher cost per serving
5. Instinct Freeze-Dried Raw Boost Mixers
Best for: Easy raw integration and everyday use
Price: $17.99 | View on Amazon
Instinct’s Raw Boost Mixers are small freeze-dried kibble pieces made from 95% cage-free chicken. You simply scoop and mix them into your dog’s Kirkland (Costco) bowl. The freeze-drying process preserves raw nutrients, enzymes, and natural flavors without refrigeration.
These mixers are especially convenient for busy pet owners who want raw nutrition benefits without the complexity of a full raw diet. They’re sized perfectly to blend with standard kibble.
Pros: Convenient, no prep, raw nutrition, shelf-stable
Cons: Can be high in protein for dogs that need controlled protein diets
How Much Topper Should You Add to Kirkland (Costco)?
A general guideline is the 10% rule: toppers should make up no more than 10% of your dog’s total daily caloric intake to avoid unbalancing the diet.
| Dog Weight | Daily Calories | Topper Allowance |
|—|—|—|
| 10 lbs | ~270 kcal | ~27 kcal |
| 25 lbs | ~520 kcal | ~52 kcal |
| 50 lbs | ~860 kcal | ~86 kcal |
| 75 lbs | ~1,145 kcal | ~115 kcal |
Always check the calorie content on the topper packaging and adjust Kirkland (Costco) portions accordingly to avoid weight gain.
Tips for Introducing Toppers to Kirkland (Costco)
1. Start small. Introduce any new topper gradually over 5–7 days to avoid digestive upset.
2. Monitor stools. Loose stools may indicate too much of a rich topper too quickly.
3. Choose complementary proteins. If your dog eats a chicken-based Kirkland (Costco) formula, try a fish or beef topper for variety.
4. Refrigerate wet and broth toppers. Opened wet food and broth should be used within 3 days.
5. Check sodium. Human broths and canned foods often contain harmful levels of salt—always choose pet-specific products.
