Dog gut health has become big business, and Dr. Marty’s ProPower Plus sits right in the middle of it — a probiotic-plus-enzyme powder you sprinkle over your dog’s food, promising better digestion, more energy, and a shinier coat. It is sold only through the brand’s own website: there is no Amazon listing, which means no comparison shopping and no third-party buyer protections.
That official-site-only model shapes this entire pro power plus review. Most of the glowing testimonials live on pages the brand controls, and some of the bolder claims floating around fan sites — including unverified talk of “cancer prevention” — deserve a hard look rather than a repeat. Below, we go through the formula, what owners actually report, the honest complaints, and the red flags you should know before buying direct.

What the Brand Says It Does
Stated as claims, not facts: Dr. Marty positions ProPower Plus as supporting gut health, digestion, metabolism, and energy — plus coat and skin health, reduced anxiety, and fresher breath. Those are broad promises for a 2.2 oz powder, and they are the brand’s claims. They are worth listing, and worth checking against independent evidence rather than taking at face value.
The Formula, Up Close
The label centers on a probiotic-enzyme blend. The enzyme side includes protease, amylase, cellulase, hemicellulase, lipase, papain, and bromelain — a broad mix aimed at helping break down proteins, starches, fibers, and fats. The probiotic side lists Bacillus coagulans, Lactobacillus acidophilus, Bifidobacterium lactis, Bifidobacterium longum, and Lactobacillus plantarum, with fructooligosaccharides (FOS) as a prebiotic to feed them. Champignon mushroom and kelp round out the formula — unusual additions that give the product a differentiator beyond the standard probiotic lineup.
On paper, that is a fuller panel than many basic pet probiotics, which often contain one or two strains and no enzymes at all. Whether the doses are meaningful is harder to judge from the label alone — pet supplement labels are not held to pharmaceutical standards of disclosure.
What Owners Report Liking
Review sites and owner write-ups most often mention improved stool consistency and less gas — the two outcomes you would hope for from a digestive topper. Shinier coats and less scratching come up next, followed by more energy and fresher breath noted by some owners. The champignon mushroom and kelp get called out as interesting differentiators by reviewers who have tried several gut-health powders.
None of that is clinical proof, and “reported” is doing real work in that sentence — but the pattern of praise at least points in the direction the formula suggests.
The Honest Complaints
First: results vary by dog. Some dogs show clear improvement; others show nothing at all. That is normal for gut-health products, but it is worth knowing before paying a premium price for a digestive powder.
Second: the price itself. This is positioned at the premium end of the category, and a 2.2 oz (62g) container does not last long for a large dog on a daily scoop. Cost per month climbs fast with bigger breeds.
Third: the official-site-only model. There is no Amazon listing, which means no Amazon buyer protections, no easy price comparison, and no verified-purchase review ecosystem to cross-check claims against. Some reviewers also mention friction around ordering and subscriptions — auto-ship programs that are easy to join and harder to leave are a recurring complaint across the supplement industry, and this brand is not exempt from that criticism.
Red Flags Worth Taking Seriously
This section matters more than the praise:
- Official-site reviews may be curated. Testimonials on a brand’s own website are marketing until proven otherwise. Treat them as such, and look for independent discussion before deciding.
- There are no independent clinical trials on this formula. The ingredients have varying levels of research behind them individually, but the product itself has not been through independent clinical testing.
- Fan-site “cancer prevention” claims are unverified. You may see dramatic health claims on blogs and forums. Do not repeat them, and do not buy based on them.
- Pet supplements are not FDA-evaluated. Like human supplements, these products are not evaluated by the FDA for safety or efficacy before sale. Consult your veterinarian before starting it — especially if your dog is on medication or managing a health condition.
A note on veterinary guidance: No review — this one included — replaces your veterinarian’s advice. Gut symptoms can signal anything from a food sensitivity to something more serious, so talk to your vet before adding any supplement, and definitely before combining one with medication.
Who Should Buy It — and Who Should Skip It
This topper fits dog owners who want a combined probiotic-plus-enzyme product, like the breadth of the strain and enzyme panel, and are comfortable buying direct from the brand with eyes open about the curated-reviews issue. If your dog has chronic digestive trouble, the vet conversation comes first — a topper is not a diagnosis.
Skip it if you want third-party verified reviews, Amazon buyer protections, or a budget option — or if the subscription-friction complaints bother you. There are cheaper probiotic-only products with wider retail availability and larger independent review bases.
Final Verdict
Dr. Marty ProPower Plus has a genuinely interesting formula — the enzyme breadth plus five probiotic strains, a prebiotic, and the mushroom-and-kelp differentiators add up to more than a me-too gut powder. The owner-reported outcomes point in the right direction: better stools, less gas, shinier coats.
But the buying context is the real story here. Official-site-only sales, curated testimonials, no independent trials, and unverified fan-site claims mean you are buying on trust in the brand rather than on independent evidence. If that trade-off works for you — and your vet is on board — the formula itself is one of the more complete options in its category. If it does not, the red flags are reason enough to pass.
Bottom line of this pro power plus review: a well-stocked formula wrapped in a buy-direct model that demands skepticism. Talk to your vet, read critically, and decide with both eyes open.
How is ProPower Plus given to the dog?
It is a powder topper — you sprinkle the recommended amount over your dog’s regular food. Follow the label’s serving guidance for your dog’s size, and introduce any new supplement gradually to watch for digestive upset.
How long before you see results?
Owner reports vary widely — some notice changes in stool consistency within a couple of weeks, others see nothing at all. Gut-health products are not instant fixes, and results depend on the individual dog, diet, and the underlying issue.
Can any dog use it?
Not automatically. Dogs on medication, with chronic conditions, or with ongoing digestive symptoms should be checked by a veterinarian first. Pet supplements are not FDA-evaluated, and a vet can tell you whether a topper is appropriate or whether symptoms need a real diagnosis.
Why is it not on Amazon?
Dr. Marty sells ProPower Plus direct through its official website rather than through Amazon. That means no Amazon listing, no verified-purchase reviews, and no Amazon buyer protections — one of the main trade-offs of the product.
