True Health Starts In Your Dog’s Gut.
DigestiveK9 is the most comprehensive, science-backed, vet recommended gut health supplement you’ll find for dogs - supporting digestion, skin, energy, and behaviour.
If your dog is struggling with gas, loose stools, itching, bad breath, low energy, anxiety or poor coat condition, it’s likely their gut microbiome is off balance and needs support.
DigestiveK9 is a multi-action daily gut health supplement, designed to support digestion, immunity, skin and nervous system for dogs of all life stages and breeds.
Most dog supplements only target one piece of the puzzle. DigestiveK9 combines amino acids, digestive enzymes and a unique blend of Pre, Para-Pro and Postbiotics to support the WHOLE of the gut - available in a simple scoop of powder sprinkled right over their regular food or in a convenient chew. Always consult your veterinarian for specific advice for your dog.

The Most Comprehensive
Gut Health Supplement
We believe good gut health goes beyond probiotics alone. That’s why DigestiveK9 is formulated with postbiotics - proven, stable actives that work where your dog needs it most.
While probiotics can struggle to survive digestion, postbiotics get to work throughout the entire gut, supporting your dog from nose to tail. Because lasting results come from looking after the whole gut, not just part of it.

FAQ
Poseidon Animal Health was founded in Australia in 2017, with a focus on targeted, evidence-based gut health solutions. After creating our successful equine range, we applied that same science-led approach to canine health. We are based in the Illawarra Region of NSW, with manufacturing facilities in Australia, New Zealand and USA. We also export to Europe, the Middle East and Asia.
DigestiveK9 is a daily gut health supplement formulated by a team of canine nutritionists, microbiologists and veterinarians to support the entire digestive tract. Available in both powder and chew formats, DigestiveK9 is designed to support digestion, immunity, skin health, and behaviour. It delivers 47.5 billion CFUs per scoop and 11.9 billion CFUs per chew - among the highest levels on the market.
DigestiveK9 stands apart in three key ways:
- It uses a powerful blend of prebiotics, postbiotics, para-probiotics, amino acids and digestive enzymes - developed using a unique canine-specific culture.
- It contains no synthetic additives or artificial preservatives - only active, non-GMO ingredients that support the whole gut.
- Our Bio-K9® blend is fermented using Lactobacillus acidophilus D2 to deliver stable, shelf-ready metabolites that help calm inflammation and support the immune system.
DigestiveK9 Powder includes our Bio-K9® blend along with organic spirulina, green lipped mussel, oat straw, organic ginger, glutamine, beef liver, and pineapple bromelain for added gut and immune support.
DigestiveK9 Chews contain the same active ingredients, bound with beef bone broth, gelatin, expeller pressed sunflower oil, tapioca starch, vegetable glycerine, and lecithin - formulated for maximum palatability and daily convenience without compromising on ingredient quality.
We recommend daily use to support your dog’s gut and overall wellbeing. DigestiveK9 is safe for all dog breeds and life stages and is designed to be used as a long-term supplement solution, so there’s no need to worry about having to wean your dog off the product and find issues return.
Modern diets, stress, medications, and environmental toxins can all impact the gut microbiome. If your dog displays signs of digestive upset, itchy skin, bad breath, food sensitivities, or low energy, it could indicate poor gut health. DigestiveK9 helps restore balance, reduce inflammation, and support better digestion, immunity, and behaviour - every day.

Introduction

While some dogs show changes quickly, best results are typically seen after 6-12 weeks of daily use.
Yes! DigestiveK9 is highly palatable in both forms. Many owners report their dog won’t eat without it! The powder blends easily with food, and the chews are often mistaken for treats - even by the fussiest eaters.
It is extremely rare, but if your dog happens to show any hesitation or disinterest in consuming our supplements after 1 week of daily feeding attempts, please reach out to our customer service team for helpful advice and further support. We’re here to help with your dog's journey to better health.
DigestiveK9 is safe to use alongside most other supplements. Each ingredient plays a specific role, and the formulation is designed to complement your dog’s existing routine.
As with any supplement, we recommend consulting your veterinarian, particularly if your dog is on existing medication or has a medical condition, . DigestiveK9 contains no chicken and is suitable for dogs with common protein sensitivities.
