CN Critical Nutrition Wet Dog & Cat Food, 5.5-oz, case of 24
Graded by The Sniff System
Purina Pro Plan Veterinary Diets CN Critical Nutrition Wet Dog & Cat Food is a wet food with beef as a primary protein, designed for critical nutritional support.
This formula has undergone AAFCO feeding trials, which is a strong indicator of nutritional adequacy. It also includes organ meats like liver and poultry giblets, plus salmon, for a diverse and bioavailable protein profile.
The formula contains unspecified meat by-products, so the exact source isn't auditable. It also includes menadione, a synthetic vitamin K3 banned in human supplements due to toxicity concerns at high doses.
Good fit for dogs and cats needing critical nutritional support, likely under vet guidance. Less ideal if you prefer to avoid unspecified by-products or menadione.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
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) . Strong fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Meat by-products anchors position 2, with zero pulses in the top 15, plus liver at position 4 (a natural taurine precursor) and salmon at position 8.

At 44/100, this formula sits below where we look for everyday picks. The lift comes from AAFCO compliance, worth 8 points to the final number: AAFCO feeding trial substantiation for not stated. The ceiling on this score is 64, set because three or more WATCH-tier ingredients appear in the deck. The cap isn't the binding constraint here. Controversial-ingredient penalty would also need to improve to reach the next band.

Controversial ingredients · 2
- meat by-productsUnspecified species. AAFCO definition allows organs, blood, bone. but the lack of a named source means quality and consistency are not auditable.
- menadioneSynthetic vitamin K3. Banned in human supplements due to toxicity concerns at high doses. Permitted in pet food but premium brands use natural vitamin K alternatives.
Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →
Wet and fresh foods contain more water than kibble (typically 65-78%). On a dry-matter basis, this food's protein content is roughly 38%, comparable to premium kibble (typically 30-45% DMB protein).
Read why each ingredient is good or bad for dogs.
- 1water
Just water. Counted on the label of any wet or fresh food. The number tells you the moisture content.
- 2protein animalmeat by-products Flagged
Unnamed organ meats and tissue. Could be nutritious, but no species is listed, so quality varies by batch.
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3protein animalbeef
Real meat. Dense in protein and iron. Some dogs are sensitive to it, but for most it's an excellent base.
Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4liver
Generic liver, usually chicken or beef. Among the most nutrient-dense ingredients a dog can eat. Named species is more informative.
- 5poultry giblets
- 6corn oil
Position 6: supporting grain. Smaller contribution to the carb deck.
- 7grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 7: supporting grain. Smaller contribution to the carb deck.
- 8protein animalsalmon
Real fish meat. Natural source of omega-3s, which kibble usually has to add back from oil.
Position 8: supporting protein. Modest contribution to total protein weight.
- 9artificial and natural flavors
- 10pork fat
Real animal fat from a named species. Clean energy source.
Position 10: supporting protein. Modest contribution to total protein weight.
- 11mineraltricalcium phosphate
Calcium and phosphorus source. Same role as dicalcium phosphate, slightly different ratio.
- 12mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 13fiberguar gum
Thickener common in wet food. Emerging research on emulsifiers and the gut microbiome, but no smoking gun in dogs yet. See why →
Position 13: trace fiber inclusion.
- 14oat hulls
- 15calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 16mineralmagnesium sulfate
Source of magnesium, a required mineral. Standard inclusion in complete diets.
- 17supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 18supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 19vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 20supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 21mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 22vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
- 23mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 24vitaminniacin supplement
B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.
- 25mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
