Trout & Salmon Limited Ingredient Formula Canned Dog Food, 13-oz, case of 12
Graded by The Sniff System
Zignature Trout & Salmon Limited Ingredient Formula Canned Dog Food is a wet food featuring trout and salmon as its main protein sources.
This formula offers reasonable protein quality, with trout providing solid amino acid coverage. The inclusion of named fish like trout and salmon also contributes to diverse, highly bioavailable protein.
The main thing to note is the absence of an AAFCO statement, which means the nutritional completeness of this food is unverified. This factor significantly impacts its overall score.
Good fit for adult dogs who do well on a fish-based diet. Less ideal if you prefer a food with verified nutritional completeness.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. Good fit for adult Labrador Retrievers and similar active sporting breeds navigating weight management. Caloric density is not declared. The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively (Brooks et al., 2014) .

At 53/100, this formula lands mid-pack. The lift comes from protein quality, worth 18 points to the final number: Reasonable protein quality. trout delivers solid amino acid coverage. The ceiling on this score is 59, set because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). The cap isn't the binding constraint here. AAFCO compliance would also need to improve to reach the next band.

- 1trout
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2fish broth
- 3protein animalsalmon
Real fish meat. Natural source of omega-3s, which kibble usually has to add back from oil.
Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4legumepeas
Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →
Position 4. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 5legumechickpeas
Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →
