Key Takeaways Native Pet’s probiotic powder scored well on ingredient density but lost points for ambiguous CFU-at-expiration language and limited peer-reviewed canine evidence. Our 6-week mixing palatability protocol showed most dogs accepted the powder when mixed into wet food, but kibble-only meals produced refusal rates above 30%. Storage stability claims for live-culture powders remain the…
Key Takeaways PetLab Co Probiotic Chews retail at $40/month on autoship ($50 one-time), which works out to roughly $0.89–$1.11 per chew depending on your bottle. The subscription model includes a soft-cancellation friction layer (account login → chat widget → retention prompts) that frequently pushes owners past their intended cancel window. Per-CFU cost is not a…
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 +…
Key Takeaways FortiFlora’s ingredient profile is narrower than most owners realize: one Enterococcus faecium strain, one animal-protein flavor, and minimal prebiotic support. Format parity matters. Powder sachets like FortiFlora and postbiotic + prebiotic sachets from competitors (including Plentum) deliver dosing precision that chews and pastes cannot replicate. Cost-per-serving varies widely. A 30-serving box of FortiFlora…
Key Takeaways Autoship programs are governed by the FTC’s 2024 amended Negative Option Rule, which requires clear consent, simple cancellation, and upfront disclosure of all material terms before a consumer is charged. The seven costliest subscription terms we see across pet supplement brands are: price-escalation clauses, automatic bundle enrollment, “free gift” paid-product conversion, non-refundable shipping…
Key Takeaways We audited certification marks and label claims across 12 dog supplement labels; the audit checked whether each displayed mark could be identified, the stated scope of the program, and whether the claim was presented without unsupported implications. The most common issue was not an obviously unfamiliar logo. It was a mark that looked…
Key Takeaways Format choice matters as much as ingredient choice — dosing accuracy, palatability, and ingredient density vary dramatically across powder, chew, and paste delivery systems. Powder sachets scored highest in our dosing-accuracy testing because pre-measured servings eliminate the measurement error we measured in scoop-based products. Soft chews win on palatability trials but carry a…

Key Takeaways FortiFlora (Purina) is the category’s best-known brand for acute digestive upset and has the largest base of real owner reviews — genuine strengths worth crediting. FortiFlora is a single-strain live probiotic (Enterococcus faecium SF68) aimed at GI upset; it does not address oral health or shelf-stability guarantees the way a postbiotic does. Plentum…
