Syntro Gut & Digestion Soft Chews for Dogs

If your dog has soft or loose stools on and off, gas that clears the room, a tummy that gurgles at night, eats grass on every walk, sniffs the bowl and walks away, or gets an upset stomach every time the food, the routine or the season changes — this was made for them.

It's not a sensitive stomach. It's gut balance. Your dog's gut is home to trillions of bacteria that digest food, keep stools firm and support the immune system. Food switches, antibiotics, stress, scavenging and age knock that balance off, and the tummy is the first to show it.

Rice and chicken settles one bad day. This supports the gut every day: 3 billion CFU of spore-forming probiotics, two prebiotic fibres and a postbiotic yeast blend, in a pork-liver soft chew your dog takes like a treat.

Made for dogs of every breed and size from 12 weeks old, puppies to seniors — and for dog parents who want a calm, happy tummy without mixing powders or hiding pills.

Four gut actives, six jobs — each one mapped to something you see every day. Not a new food. Not a powder to mix.

1. Firm, regular stools. Spore-forming probiotics and two prebiotic fibres help maintain the gut balance behind normal stool consistency.

2. Comfortable digestion. Supports digestion with less gas, bloating and tummy gurgling.

3. A steady tummy through changes. Helps keep the good bacteria topped up through food switches, travel, kennels and busy weeks (after antibiotics, ask your vet about timing).

4. A healthy appetite. A settled gut supports normal appetite, so picky eaters and grass grazers have less reason to skip meals.

5. Immune support from the gut. Most of a dog's immune system sits in the gut. The postbiotic yeast blend supports the gut lining and normal immune function.

6. Easy to give. A soft, pork-liver flavoured chew from human-grade ingredients. No powders, no pill pockets, no fuss.

Your dog's gut is an ecosystem of trillions of bacteria. When the helpful ones are in charge, food is digested properly, stools are firm and the immune system is supported. Most "sensitive stomachs" aren't about the food bowl. They're about what's happening in the gut.

What's actually happening:
Food switches, antibiotics, stress and scavenging knock the good bacteria back → less helpful bacteria take over.
Food ferments instead of digesting → gas, bloating and gurgling.
The gut doesn't hold water and fibre as it should → soft or loose stools, grass eating and skipped meals.

Why what you've tried hasn't fixed it:
Rice and chicken settles one bad day, then it starts again.
Switching food again is one more change for an unsettled gut.
Probiotic powders need mixing, get left in the bowl, and many strains don't survive stomach acid.
Pumpkin or yoghurt adds a little fibre, but does nothing for the balance of bacteria.

How Syntro Gut & Digestion works differently. Three layers of support in one tasty chew:

✓ 3 billion CFU of spore-forming probiotics (Bacillus coagulans, B. subtilis, B. clausii) — spores are built to survive stomach acid and become active in the gut.
✓ Two prebiotics, FOS and GOS — fibres that feed the good bacteria.
✓ A postbiotic yeast blend — supports the gut lining and normal immune function.
✓ A pork-liver soft chew — dogs take it like a treat, so you never miss a day.

1–3 chews a day, by weight. That's it.

Here's what dog parents typically report. The gut rebalances gradually, so give it one to two weeks of daily chews for the first changes — some notice sooner.

Days 1–14 — the settling-in phase. The probiotics reach the gut every day and the prebiotics start feeding the good bacteria. Many dog parents see firmer, more regular stools by the end of week two.

Weeks 2–4 — the balance phase. Gas and gurgling ease off, and the upset-tummy days get rarer, even after a scavenging walk or a change in routine.

Weeks 4–8 — the happy-tummy phase. Stools stay firm, appetite comes back and many dogs eat less grass. Mealtimes stop being a negotiation.

Days 60–90 — the new-normal phase. The support builds: a calm, regular tummy becomes your dog's normal. This is when dog parents stop planning their day around their dog's tummy.

Food switches, travel, stress and age keep testing the gut. The daily chew keeps supporting it. That's why most dog parents keep going past the first jar.

Give the daily amount for your dog's weight, by hand as a treat or crumbled over food:

Under 25 lb (11 kg): 1 chew a day
25–75 lb (11–34 kg): 2 chews a day
Over 75 lb (34 kg): 3 chews a day

For all breeds and sizes, from 12 weeks old. Each jar holds 60 soft chews: 30 days for a dog on 2 chews a day (60 days for a small dog, 20 days for a large one). Keep fresh water available. Store in a cool, dry place and reseal the jar after use.

This is a complementary feed for dogs, not a medicine, and it doesn't replace a balanced diet or your vet's advice. Do not exceed the daily amount. If your dog is pregnant, nursing, on medication or under treatment, ask your vet first. If loose stools last more than 48 hours, or there is vomiting, blood or your dog seems unwell, see your vet. Not for cats. Keep out of reach of children.
