Singles Limited Ingredient Pork & Squash Grain-Free High-Protein Dry Dog Food, 22.5-lb bag
Graded by The Sniff System
ACANA Singles Limited Ingredient Pork & Squash is a grain-free dry dog food, featuring pork and pork liver as its main protein sources.
This food offers a strong protein profile, with pork as the primary ingredient, which means high biological value for your dog. It also includes quality fat sources like named pork fat and fish oil, providing beneficial EPA and DHA. The formula's nutritional adequacy is substantiated by AAFCO feeding trials.
You'll find some legume stacking here, with chickpeas and lentils appearing in the top ingredients. This is partially mitigated by the inclusion of pork liver, a natural taurine precursor.
Good fit for adult dogs, especially those needing a limited ingredient or grain-free diet. Less ideal if you prefer foods without legumes.

Good fit for adult Golden Retrievers navigating diet-associated DCM concerns. Pork anchors position 1, with 2 pulse-family ingredients in the top 15 (chickpeas at position 5, lentils at position 7), plus pork liver at position 3 (a natural taurine precursor). In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) .

Solid grade. 74/100 (B) reflects the structural fit of this formula against The Sniff System's eight scoring components. Protein quality did the heavy lifting (+23 points): Strong protein profile with pork as the primary ingredient, delivering high biological value. What we'd flag for vet discussion: controversial-ingredient penalty (-2 points). Contains high legume stacking. Multiple pulse-family ingredients in top 15. Mitigated by taurine supplementation or organ meat (natural taurine precursor) in top 10. A-tier is 1.0 points away. Trimming controversial-ingredient penalty is the most direct route.

Read why each ingredient is good or bad for dogs.
- 1protein animalpork
Real meat. Dense protein and fat, though less common in dog food than chicken or beef.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalpork meal
Pork cooked into a dry concentrate. Per pound, more protein than fresh pork.
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3protein animalpork liver
Organ meat. Dense in B vitamins, iron, and vitamin A. Among the most nutritious ingredients on any label.
Position 3. Named organ meat this high is a strong build choice. Concentrated source of taurine, glutamine, and B-vitamins.
- 4vegetablesweet potato
Complex carb with fiber and beta-carotene. Gentle on the stomach.
Position 4: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 5legumechickpeas
Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →
Position 5. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 6pork fat
Real animal fat from a named species. Clean energy source.
Position 6: supporting protein. Modest contribution to total protein weight.
- 7legumelentils
Same concern as peas. Affordable plant protein, but when they pile up in the top 5 ingredients, it's a flag. See why →
Position 7. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 8lentil fiber
Position 8. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 9vegetablevegetable
Unnamed vegetable. No way to know what species. Named vegetables are far more transparent.
Position 9: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 10fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 10. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 11natural pork flavor
Position 11: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 12vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
Position 12: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 13fruitcranberries
Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.
Position 13: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 16supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 17vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 18supplementdried kelp
Natural source of iodine and trace minerals. A common premium-brand inclusion.
- 19mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 20preservative naturalmixed tocopherols
Natural vitamin E used to keep fats from going rancid. The good kind of preservative. See why →
- 21vitamin a acetate
- 22vitaminvitamin d3 supplement
The active form of vitamin D dogs need. Required for calcium absorption and bone health.
- 23vitaminniacin supplement
B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.
- 24vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
