Singles Limited Ingredient Lamb & Apple Grain-Free High-Protein Dry Dog Food, 22.5-lb bag
Graded by The Sniff System
ACANA Singles Limited Ingredient Lamb & Apple is a dry food featuring lamb and lamb liver as its main protein sources.
This formula boasts a strong protein profile with lamb as the primary ingredient, offering high biological value. It also includes quality fat sources like fish oil, which provides beneficial EPA and DHA. Plus, the formula has undergone AAFCO feeding trials.
The ingredient list shows several pulse-family ingredients like chickpeas and lentils appearing in the top 15. This high legume stacking is a pattern the FDA has investigated, though it's partially mitigated here by the inclusion of lamb liver.
Good fit for dogs needing a limited ingredient diet with lamb as the primary protein. Less ideal if you prefer foods without high legume content.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for adult Golden Retrievers navigating diet-associated DCM concerns. Lamb anchors position 1, with 2 pulse-family ingredients in the top 15 (chickpeas at position 5, lentils at position 7), plus lamb 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) .

Read why each ingredient is good or bad for dogs.
- 1protein animallamb
Real meat. Often used for dogs with chicken or beef sensitivities. Slightly higher fat content than chicken.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animallamb meal
Lamb cooked down to a dry concentrate. Per pound, more protein than fresh lamb. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3protein animallamb liver
Organ meat. Same nutrient-density story as chicken or beef liver, dense in B vitamins, iron, vitamin A.
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.
- 6fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 6. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 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.
- 9fruitapples
Real fruit, some fiber and antioxidants. The amount in kibble is too small to matter much.
Position 9: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 10fatsunflower oil
Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.
Position 10: trace fat. Below the level that materially shifts the fat profile.
- 11natural lamb flavor
Position 11: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 12lamb tripe
Position 12. Small organ inclusion. Functional but not a primary contributor to the protein profile.
- 13vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
Position 13: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 14fruitcranberries
Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.
Position 14: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 15mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 16supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 17supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 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.
- 20vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 21preservative naturalmixed tocopherols
Natural vitamin E used to keep fats from going rancid. The good kind of preservative. See why →
- 22mineralselenium yeast
Organic selenium grown in yeast. The form premium brands use, gentler and more bioavailable than sodium selenite.
- 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.
- 25vitamincalcium pantothenate
Same as d-calcium pantothenate. Vitamin B5 in standardized form.
