A healthy gut is key to your dog’s overall vitality, immunity, and energy.

O2B K9⁺ Synbiotic™ is a natural, whole-food supplement formulated to optimize gut health and digestion. Combining 13 strains of live probiotics, prebiotics, and nutrient-dense ingredients like NZ Greenshell™ Mussel and kiwifruit powder, this supplement supports the gut-brain axis, immune system, and energy production.

Designed specifically for dogs using human grade ingredients O2B K9⁺ Synbiotic™ is a powerhouse product that promotes natural cleansing, nutrient absorption, and balanced gut function, helping your dog thrive from the inside out.

FAQs +

How does O2B K9⁺ Synbiotic™ improve my dog’s digestion?
This supplement combines 13 strains of live probiotics with prebiotics like Inulin and digestive enzymes found in kiwifruit powder to optimise digestion, nutrient absorption, and gut balance.

What makes live probiotics better than freeze-dried ones?
Live probiotics in O2B K9⁺ Synbiotic™ are active from the moment they enter your dog’s mouth, unlike freeze-dried probiotics that need reactivation in the gut. This ensures faster, more effective support for gut health.

How soon will I see improvements in my dog’s health?
Many owners notice improvements in digestion, stool quality, and energy levels within a few days to two weeks. For immune and long-term gut health benefits, consistent use over 4–8 weeks is recommended.

Is O2B K9⁺ Synbiotic™ safe for daily use?
Yes! This natural, food-based formula is safe for daily use to maintain ongoing gut health and overall wellness.

Can this supplement be given alongside other medications?
O2B K9⁺ Synbiotic™ is a food-based supplement and generally safe with medications. However, consult your vet if your dog is on prescription treatments.

Why doesn’t the label state the exact number of probiotics?
Our probiotics are naturally fermented and alive, so their numbers multiply and change over time. Unlike freeze-dried probiotics, O2B K9⁺ Synbiotic™ focuses on ensuring live bacteria are active, not just counted.

Who is K9⁺ Synbiotic for?

Your dog gets an upset tummy, gas, or irregular stools more often than you'd like
You've noticed them eating grass more than usual

Healthy digestion and nutrient absorption with 13 strains of live probiotics working alongside prebiotic fibre to help your dog get more from every meal
Natural cleansing of the digestive system through kiwifruit powder, valued for its natural enzymes and fibre
The immune system, since a healthy gut plays a central role in keeping your dog's natural defences strong
Energy levels and vitality through nutrient-dense NZ ingredients like Greenshell™ Mussel, venison, and deer liver, chosen to support day-to-day wellbeing from the inside out

So good!

I've been giving my small dog K9+ Synbiotic, and it's helped a lot. We will definitely be buying again!

Great!

We were able to decrease the K9+ Joints by 4 tablets a day when we started this gut health product. Our Border Collie is 10 years old and has bad hips, didn't think a gut health supplement would help with that!

Has really helped

My daughter's dog's breath has been an unpleasant, sour odour and he has had some dry skin, but using O2B K9+ Synbiotic has really helped both issues.

Blown away

We came in looking for Greenshell mussel powder for our greyhound’s itchy skin issue (dandruff) but were talked into buying this product by the owner because it’s specifically designed to support healthy skin by going through the gut. Well! What a transformation in just FOUR days, Willo has stopped the scratching so that her skin can begin to heal. We were so blown away that we had to come back and buy the human version for ourselves 🙂
