Our Product Testing Process

Independence First

The credibility of a review depends on the independence of the reviewer. So we start with a rule that does not bend: we buy every product we review at full retail price. We do not accept free samples, sponsored units, or pre-release products from manufacturers for the purpose of review. When a company sends us something unsolicited, we disclose it, and it does not change how or whether we test.

This matters because a product chosen from a store shelf is the product you will actually receive. A hand-picked sample from a manufacturer may not be. Testing the retail version is the only honest way to tell you what to expect.

Step 1: Retail Purchase and Intake

We purchase products through ordinary consumer channels, the same way you would. On arrival, we photograph the packaging, record the lot number and expiration date, and document every claim printed on the label. This creates a baseline we can hold the product against throughout testing.

Step 2: The 30-Day Trial

Each product is fed to volunteer dogs over a structured 30-day trial period, following the manufacturer’s recommended serving. Volunteer dogs are owned by trusted handlers who log daily observations. We track:

  • Palatability — whether the dog accepts the product readily, needs it hidden in food, or refuses it.
  • Stool quality — consistency and regularity, recorded on a standard scale throughout the trial.
  • Tolerability — any signs of digestive upset, refusal, or adverse reaction.
  • Practical factors — ease of dosing, packaging, storage requirements, and smell.

Thirty days is long enough to observe a meaningful pattern without overstating what a short trial can prove. We are careful not to attribute unrelated health changes to a supplement.

Step 3: Palatability Scoring

Palatability is measured, not guessed. We record acceptance across multiple dogs and multiple servings, and we note whether acceptance holds over the full trial or fades. A product that dogs eat eagerly on day one but reject by day twenty scores lower than one that stays consistently accepted.

Step 4: Stool Quality Tracking

For gut-focused products, stool quality is a primary outcome. Handlers log consistency daily using a standardized fecal scoring system, and we compare the trial period against a baseline. We look for trends across the group, not anecdotes from a single dog, and we report results honestly even when they are unimpressive.

Step 5: Independent Lab Verification

Label claims are verified through independent laboratory testing of live organism counts (CFU) and, where relevant, ingredient identity and purity. This is the step that separates marketing from reality. If a label promises a certain potency and the lab finds materially less, that discrepancy is reported and reflected in the product’s Label Accuracy and Third-Party Testing scores.

What We Do With the Results

Trial data and lab results feed directly into our scoring rubric. We publish what we found, including results that are unfavorable to a product, and we update our assessments when new testing changes the picture.

Our loyalty is to the reader and the dog, never to the brand. If a product disappoints, we say so plainly.
