Our Independent Testing Team —
On this page
We compared them on the five criteria we think matter most.
The five criteria we judge by
- Published canine clinical trial on the finished product (not just ingredient studies)
- Postbiotic / shelf stability (does it survive to the bowl?)
- Oral-health coverage (breath and biofilm — usually ignored)
- Multi-system formulation (gut + oral + immune + coat)
- Full dose transparency (every ingredient dosed on the label)
Head-to-head comparison
| Format | Chews / powder | Flavorless powder sachet (2 g) |
| Finished-product canine trial | No finished-product trial | Yes — double-blind RCT, n=24, p=0.004 |
| Shelf stability | Live culture (viability varies) | Postbiotic — no CFU decay |
| Oral-health coverage | No | Yes (postbiotic: 98% biofilm disruption in vitro) |
| Multi-system | Narrow / single focus | Gut + oral + immune + coat (9 actives) |
| Dose transparency | Human-grade sourcing | Fully dosed label |
Where Dog Is Human is genuinely good
To be fair, Dog Is Human earns its reputation for a human-grade marketing angle that resonates with ingredient-conscious owners. “human-grade” is a sourcing claim, not an efficacy claim. It does not tell you whether the finished product was tested in dogs — and here it was not, to our knowledge.

Frequently asked questions
Why does postbiotic stability matter?
Live-culture probiotics can lose viability on the shelf. A heat-treated postbiotic does not depend on living organisms, so the dose you buy is the dose your dog gets.
