Your 90-day guide

gut stuff is easy to forget once it stops. in three weeks you genuinely will not remember whether the bad days were most days or just a few — and that's the difference between "it's working" and "i'm not sure."

so score this week honestly, before anything changes.

screenshot the scores, or write them on the jar lid. you'll want them at week 4.

when someone tells us it isn't working, dosing is the first thing we check — and it's often the whole answer. probiotics are a numbers game: you need enough live bacteria arriving to actually shift the balance of what's already in there.

90 chews per jar. if your dog is on more than one a day, spread them across meals rather than giving them all at once — a steady supply beats one big delivery.

this is the one chew in our range where you're not being asked to wait months on faith. the gut lining renews itself in days, and the bacterial population shifts almost as fast — so the feedback comes quickly. here's the order things tend to happen in.

let's get ahead of this, because it catches people out and it's the main reason someone stops after a week.

you're doing two things at once: adding live bacteria, and adding a prebiotic fiber that feeds them. fermentation is how that fiber gets used, and fermentation makes gas. so for some dogs the first week or two brings more wind and looser stool before it gets better, not less. it's the gut population reshuffling, and it usually settles inside two weeks.

what isn't an adjustment period: watery diarrhea that doesn't stop, vomiting, blood, a dog who goes off food or seems unwell, or anything that hasn't settled after two weeks. stop the chews and call your vet — and email us, because we want to know.

we need to be straight with you, because this is the single most common way people end up disappointed with this particular chew.

the chew built for that is Skin & Coat — omega 3, 6 and 9 plus vitamin E, working on the skin barrier itself. a lot of our customers run both, and that combination makes sense: the probiotic supports the system underneath while the skin chew rebuilds the barrier on top. what doesn't work is expecting the probiotic to do the second job by itself.

here's the thing almost nobody tells you about dog probiotics: most of them are dead before they arrive.

stomach acid sits somewhere around pH 1.5 to 3.5. the common strains — the lactobacillus family most cheap probiotics use — are simply not built to survive that. they get destroyed on the way through, which means the CFU count on the label is what went in, not what got where it needed to go.

ours is a spore-former. Bacillus coagulans wraps itself in a tough protective shell and stays dormant through the stomach — acid, heat and moisture don't touch it. it wakes up in the intestine, which is the only place it was ever meant to work.

• Bacillus coagulans · 120 million CFU per chew. the strain is BC30 (GBI-30, 6086) — a named, patented, clinically studied one. most competitors won't tell you which strain they use, and there's usually a reason for that.
• FOS prebiotic · 200 mg. this is the half people skip. probiotics are living things and they need feeding — without a prebiotic they die off long before they establish. FOS is a fiber that reaches the colon undigested and feeds them directly. it also helps regulate water in the gut, which is what firms stool without making it hard.

per chew. duck flavor, 90 to a jar, made in the USA, third-party verified to USP, AOAC and FCC standards.

this is the easiest chew in the range to get down — it's small, it's duck-flavoured, and most dogs take it as a treat. if yours is holding out:

• Crumble it into wet food. break it small so it can't be eaten around.
• Warm the food slightly. ten seconds in the microwave lifts the smell of dinner over the smell of the chew.
• Press it into something sticky. peanut butter (xylitol-free), plain pumpkin — pumpkin is a good pick here anyway — or cream cheese.
• Make them earn it. ask for a sit first. a chew that's a reward gets eaten far more often than one that appears in a bowl.

the chew is doing its job. these are the things that quietly cancel it out, and all four are free to fix.

• Changing their food mid-trial. the most common one. a new food resets the whole experiment and you'll never know which change did what. pick one diet and hold it for the full 90 days. if you genuinely have to switch, do it over 7–10 days, mixing a little more of the new in each day.
• Table scraps and rich treats. a gut you're trying to settle does not want fatty leftovers on a wednesday. this is the single fastest way to reverse a good week.
• Eating too fast. a dog who inhales dinner swallows a lot of air, and that shows up as gas and discomfort that has nothing to do with bacteria. a slow-feeder bowl or a muffin tin fixes it for a few pounds.
• Not enough water. the prebiotic fiber works by managing water in the gut, so it needs water to work with. fresh bowl, refilled daily, and a splash over dry food doesn't hurt.

this chew supports the bacterial balance in a healthy digestive system. a few other things look identical from the outside and won't respond to it, so they're worth ruling out rather than waiting on.

• Parasites — giardia, worms, coccidia. extremely common, especially in puppies and rescues, and they cause exactly this picture. a stool sample at the vet is cheap and settles it in a day.
• A true food allergy or intolerance. if the same symptoms come back every time a particular protein is in the bowl, no probiotic out-runs that. it needs an elimination diet with your vet.
• Pancreatitis or an inflammatory gut condition. repeated vomiting, a hunched or painful belly, real lethargy, or refusing food — that's a vet visit today, not a supplement.
• Something they swallowed. sudden vomiting and straining in a dog who was fine yesterday is an emergency until proven otherwise, particularly in young dogs.

a jar looks like a jar. what matters is what a full 90-day run costs for a dog your dog's size — because that's the commitment, and you should be able to see the whole number before you start.

that's the subscriber price, and the jar count is exactly what your dog eats in 90 days — no rounding, no upsell math. free shipping either way.

for context: one vet visit for persistent loose stool, before any tests, generally costs more than a full 90-day run — and a prescription gut diet costs more per month than this does.

put three reminders in your phone now: 4 weeks, 8 weeks and 12 weeks from today. when each one goes off, come back here and re-score the same five things. week 12 is the one that closes the loop — it's the mark the whole guarantee is built around.

because this chew works fast, week 4 is a real checkpoint here rather than an early peek. if two of those lines haven't dropped by then, go back to chapter 9.

The 90-day guarantee, plainly

• Give it 90 consecutive days at the correct dose for your dog's weight. that's the deal on your side, and it's why chapter 2 is where it is.
• If there's no improvement at the end of it, email us and we'll refund you. you won't have to argue for it.
• It doesn't cover taste. if your dog won't eat them, that's a problem we want to solve with you — chapter 7, or just email.
• Anything damaged, missing or wrong is fixed straight away, whatever day of the 90 you're on. no conditions on that one.

it runs 90 days rather than 30 for a different reason than our other chews. you'll usually know inside a month whether this is working — the 90 days is about proving it holds, because gut balance is a population you maintain, not a repair you finish.
