THE SMALL DOG DIFFERENCE
The scratching. The soft stool. The dull coat. The low energy. They look like four different problems. They all trace back to one place — a gut that was never given what a small dog specifically needs.
Every probiotic on the market doses for a 70 lb Lab. At your small dog's actual weight — that formula does nothing. Or worse, overwhelms her. Little Belly is the only formula that accounts for small dog biology from the start. Not scaled down. Built for this.
WHY POWDER - NOT CHEWS
Heat kills probiotics. Binders kill probiotics. Both are required to make a chew. So by the time that chew reaches your dog's gut — the bacteria you paid for are dead.
Powder arrives alive. Uncoated. Bioavailable. For a small dog whose gut transit is already faster than a large breed, this isn't a minor difference. It's the whole game.
Half a scoop per day. One jar lasts 60 days at the correct small dog dose. Every probiotic chew on the market doses for a large dog. At your small dog's actual dose — you're getting 15 days. Maybe 20. They don't put that in the ad. We just did.
THE MECHANISM
One scoop. Four things happen.
Every single day.
Not a probiotic. A system. Eleven ingredients. Each with one job. Dosed for a small dog's body. This is what happens after you sprinkle it on their food.
DAYS 1-7
The Foundation
Pumpkin powder feeds the probiotics before they colonize. Enzymes hit every meal. Gas reduces. Stool begins to shift. Most owners notice within the first week.
DAYS 8-14
The Repair
L-Glutamine patches gaps in the gut wall. Allergens stop crossing. The immune system stops firing. Stool firms noticeably. Something feels different. It is.
DAYS 15-30
The Coat Shift
Lipase has been unlocking dietary fats with every meal. They now reach the hair follicle. The groomer asks what changed. The answer is half a scoop a day.
DAYS 30+
The Long Game
Beta glucan recalibrates — not suppresses — the immune system. Less seasonal reactivity. Fewer flare-ups. Calmer skin. Running automatically in the background.
NOTHING TO HIDE
No proprietary blends hiding the math. Every dose published. We want you to look up every ingredient — because you'll understand why it's there.
Pumpkin Powder
3,000 MG PER SCOOP
Nature's gut dial. Too loose — it firms. Too hard — it softens. It literally adjusts to what your dog needs. 3,000mg isn't a courtesy amount — it's a therapeutic dose. Most brands sprinkle in a fraction and list it on the label. That's decoration. This is the real thing.
🐾Fast gut transit in small dogs means fiber works harder here. This dose accounts for that specifically.
L-Glutamine
250 MG PER SCOOP
Your dog's gut wall has functional gaps. Allergens crawl through. The immune system fires. L-Glutamine patches those gaps from the inside. Seal the wall. The scratching stops because the war stops.
🐾Leaky gut hits proportionally harder in small breeds. This is the direct repair — at the right small dog dose.
Beta - 1, 3 Glucan
100 MG PER SCOOP
Feeds beneficial gut bacteria and recalibrates the immune system — not suppresses, recalibrates. A dial stuck on full volume. Beta glucan turns it down. Zero impact on actual immune protection.
🐾Immune overreaction is a small dog hallmark. This is the direct address for chronic seasonal reactivity.
DGL Licorice Root
100 MG PER SCOOP
Regular licorice raises blood pressure. They removed that part. What's left tells the stomach to produce its own protective mucus — a self-healing layer. Car nausea. Post-meal discomfort. Sensitive stomach.
🐾Sensitive stomachs are disproportionately a small dog issue. This addresses the lining directly.
Lactobacillus fermentum
1 BCFU PER SCOOP
Colonizes right next to gut-associated immune tissue — where 70% of the immune system lives. This is the strain most closely linked to reduced allergy symptoms and improved coat. When owners notice the coat change around day 18 and can't explain it — this is why.
🐾 This strain colonizes near the gut-immune junction — the most critical real estate in a small dog's gut where immune overreaction starts.
Acacia Gum
100 MG PER SCOOP
A prebiotic fiber with a specific job — feed the good bacteria without feeding the bad ones. It also slows gut transit. For a small dog whose gut moves faster than a large breed, slowing transit means more time to actually absorb nutrition from every meal.
🐾Slowing transit directly addresses small dog physiology. More absorption time = more nutrition per meal.
Slippery Elm Bark
50 MG PER SCOOP
Forms a gel. Coats the intestinal wall. A calm, protective layer between the gut lining and everything that irritates it. Gentle enough for a 6-week-old puppy. Effective enough for a 14-year-old senior.
🐾A soothing film on a tube that's been inflamed for months. Gentle and precise. Works at any age.
Bacillus Coagulans
2 BCFU PER SCOOP
Most probiotics die in stomach acid before they reach the gut. This one doesn't. It forms a protective spore. Travels through intact. Wakes up in the intestine — exactly where it needs to be. Arrives alive.
🐾4 billion that arrives beats 30 billion that doesn't. This is the only strain that reliably survives delivery.
Enzyme Blend
25 MG . 5 ENZYMES
Five enzymes. One headliner: Lipase. Without it, every omega fatty acid you feed passes straight through — unused. With it, those fats reach the hair follicle and the skin barrier. The direct line between gut and coat.
🐾This is why the groomer asks what changed around day 18. Fat absorption is the engine behind coat health.
Lactobacillus casei
1 BFCU PER SCOOP
The gut wall defender. Builds tight junction proteins that hold intestinal cells together — sealing the lining from the inside. If your dog has been on antibiotics, this is the strain that helps rebuild what got wiped out.
🐾Antibiotic recovery is proportionally harder in smaller dogs. This strain specifically supports rebuilding.

Jessica T. — French Bulldog — Brooklyn
4.5 LBS . FINALLY BUILT FOR HER SIZE .
""Finally something that actually means small."
Amanda R. — Chihuahua — San Diego
GROOMER ASKED WHAT HAD CHANGED
"She said her coat felt completely different - softer, fuller, less breakage."
Lauren K. — Maltese — Arizona
SHE BROUGHT HER TOY FIRST TIME IN A YEAR
"She brought me her toy. I sat on the floor and cried."
Diane F. — Pomeranian — Minnaepolis, MN
VET LOOKED IT UP IN THE APPOINTMENT
"She didn't say anything negative — which from a vet feels like a huge win."
Melissa C. — Bichon Frise — Charlotte
I WAS SKEPTICAL . THEN ORDERED 3-JARS
"I don't say this lightly because I've rolled my eyes at every supplement we've tried."

YOU HAVE UNLOCKED EVERYTHING
Every option includes every bonus. The only difference is how long your supply lasts.
NO RISK. NO FINE PRINT.
Most guarantees are 30 days. Some are 90. Ours is 365. A full year. Because we're not interested in customers who feel pressured to decide fast — we're interested in dogs who actually get better. Full refund. No questions. No product return required. No fine print.
STILL HERE? GOOD.
Almost certainly. A standalone probiotic is one ingredient. Little Belly is 11. Prebiotic fiber to help bacteria colonize. Enzymes to unlock fat absorption. L-Glutamine to repair the gut lining. Beta glucan to recalibrate immunity. A probiotic chew and a complete gut system are not the same product. They share a category name. That's it.
