What is the best gut health supplement for dogs?

Look for prebiotics, a probiotic and postbiotics together, rather than a single probiotic strain. Prebiotics feed the beneficial bacteria, the probiotic adds them and postbiotics support the gut lining. Juno Daily combines all three with slippery elm in one daily scoop, with every dose published.

Key takeaways

  • Each scoop gives 250mg chicory root inulin, 350mg MOS, 2 billion CFU of Calsporin Bacillus velezensis and 15 billion postbiotic cells.
  • Slippery elm at 200mg per scoop helps soothe the digestive tract.
  • Start gently with a quarter to half scoop for the first few days, then build up to the full serving.
  • See your vet for blood in the stools, repeated vomiting or diarrhoea lasting more than 48 hours.

Gut problems often overlap with skin and joint issues. Explore our dog supplement for itchy skin and joint supplement for dogs with sensitive stomachs.

Why so many gut chews fall short


Most soft chews are baked, and heat can damage live cultures before the pouch reaches your shelf.

Juno pairs a robust spore forming probiotic with prebiotics and postbiotics.

MAGIC!

We call this the magic dust. Our Frenchie had terrible wind and loose stools for years. Within five days of starting Juno his tummy is silent and his bathroom habits are perfect.

Added Bonus!

I originally bought this to support his mobility but the change in his digestion was the most shocking part. No more frantic middle of the night trips to the garden.

Replaced Other Pastes

I spent years buying separate probiotic pastes and pumpkin purees. We finally found a daily powder that works. His tummy gurgles are gone and he seems calmer and brighter in himself.

Dog gut health supplements: what vets look for

Most gut problems in dogs are mild and everyday: soft stools, wind, grass eating. Here is how to choose a gut supplement, and when to skip it and call your vet.

Signs your dog's gut needs support

Soft or changeable stools, frequent wind, a gurgling tummy, eating grass, scooting, a picky appetite, and itchy skin that flares alongside digestion. One sign on its own rarely matters. A pattern over a few weeks is worth acting on.

Probiotic, prebiotic and postbiotic: what each one does

A probiotic adds friendly bacteria. A prebiotic is the fibre those bacteria feed on. A postbiotic is made from inactivated bacteria, so it supports the gut lining without needing to survive the stomach.

Juno Daily uses all three in every scoop: 250mg chicory inulin and 350mg MOS as prebiotics, 2 billion CFU of Calsporin® Bacillus velezensis as the probiotic, and 15 billion cells of postbiotics, plus 200mg slippery elm.

How to choose a dog gut health supplement

  • A dog-specific probiotic strain with a stated CFU.
  • A strain that survives stomach acid. Spore-forming strains do.
  • Prebiotics in the same scoop, so the good bacteria have something to feed on.
  • Every dose printed on the label.
  • No binders, sugars or fillers.

How to start, and what to expect

Start with a quarter to half scoop for three or four days, then build up to the full serving for your dog's weight. Mix it into food. A splash of water helps it coat kibble.

Many owners notice steadier stools within two weeks. Give it at least 60 days of daily use before you judge the bigger picture.

Daily support or a probiotic paste?

Pastes are made for short bursts, such as a few days of upset. A daily gut supplement suits dogs whose digestion is never quite settled, and dogs rebuilding after a course of antibiotics, once your vet agrees.

When a supplement is not the answer

Blood in the stools, repeated vomiting, diarrhoea lasting more than 48 hours, a swollen or painful tummy, weight loss, or a dog who stops eating all need a same-day call to your vet. Puppies and older dogs dehydrate faster, so act sooner with them. A supplement supports a well dog. It does not replace a diagnosis.

Common questions about dog gut health


  • Juno Daily is built for sensitive stomachs. Slippery elm soothes the gut lining while the cultures settle in. Start with half a scoop for the first three days so their system adjusts gently.

  • Excess wind often comes from undigested food fermenting in the gut. The probiotic and prebiotics in Juno support efficient digestion and a balanced gut flora. Sudden or severe changes in wind or stools need a vet.

  • Dogs eat grass for many reasons, sometimes to settle an unsettled stomach. A daily serving of Juno supports a settled digestive environment with Calsporin Bacillus velezensis, prebiotics and slippery elm. If grass eating comes with frequent vomiting, see your vet.

  • This is a choice for purity and potency. To hold a soft chew in shape, manufacturers use up to fifty per cent binders, glues and flours, plus heat processing that can compromise probiotics. Juno is one hundred per cent active. You pay for ingredients, not flour.

  • It is not recommended. The canine gut is different from ours, so human probiotics and yogurt are not designed for dogs. Juno Daily uses Calsporin Bacillus velezensis, a spore forming probiotic used in animal nutrition. Spores are naturally robust, which helps them through the stomach.

  • Often, yes. An unsettled stomach can put a dog off their food, and slippery elm supports a comfortable gut lining. We also use natural flavours that dogs love, so Juno mixes into meals without a fight. If yours still says no, our Fussy Dog Guarantee covers you.

  • Often, yes. Syringe pastes are made for short term upsets. Juno Daily is built for daily, long term gut support instead. Once your dog is settled on the daily powder, many owners find they reach for pastes less often. Keep one in the cupboard for one off upsets.

  • Yes, with your vet's agreement. Antibiotics affect the good bacteria as well as the bad. Prebiotics feed the gut, the probiotic adds good bacteria back, and postbiotics support the gut barrier. Ask your vet when to start.

  • Bad breath usually starts with the teeth, so see your vet and keep up dental care. Digestion can play a part too, and Juno Daily supports healthy digestion and a balanced microbiome.

  • No. Our powder is shelf stable thanks to specialised moisture lock packaging. Keep the pouch sealed in a cool, dry cupboard and it holds its potency for the life of the bag. No fridge required, and no need to decant it into another container.

  • Scooting is often linked to soft stools that do not empty the anal glands naturally. Our prebiotic fibre and probiotic support normal stool consistency, which supports natural gland emptying. Persistent scooting needs a vet check.

  • It can play a part. Up to seventy per cent of your dog's immune system lives in their gut, and gut health is closely linked to skin health. Supporting the gut is one part of supporting itchy paws and skin, alongside your vet's advice.
