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.
Digestive-K9 are 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, Digestive-K9 are designed to support digestion, immunity, skin health, and behaviour.
Digestive-K9 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.
Digestive-K9 contain our Bio-K9® blend along with organic spirulina, green lipped mussel, oatstraw, organic ginger, burdock root, apple pectin and Ninjin carrot fibre for added gut and immune support.
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. Digestive-K9 help restore balance, calm inflammation, and support better digestion, immunity, and behaviour - every day.
We recommend daily use to support your dog’s gut and overall wellbeing. Digestive-K9 are safe for all dog breeds and life stages and is designed to be used as a long-term supplement solution. Many customers who have stopped feeding Digestive-K9 have reported their dog's issues returned, prompting a swift return - "this stuff really works!"
Chews Daily Feed Rate
Depending on your dog’s weight, feed from 1 up to 5 chews per day (see table below for reference):
- Up to 6kg – 1 Chew
- 7kg-15kg – 2 Chews
- 16-20kg – 3 Chews
- 21-30kg - 4 Chews
- Over 30kg - 5 Chews
*If your dog is between weights, it is safe to round up. For example, a 7kg dog would receive 2 chews per day.
Introduction
Introduce slowly over 14 days, starting with ¼ of the recommended serve and increasing gradually. For dogs under 5kg, begin with ½ a chew.
While some dogs show changes quickly, best results are typically seen after 6-12 weeks of daily use.
Yes! Digestive-K9 are highly palatable - we've recently modified our recipe to make them that much tastier! Dogs love the flavour, primarily thanks to the addition of natural hickory smoke which mimics the mouth-watering smell of barbecued yumminess (without the meat!)
Digestive-K9 are 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. Digestive-K9 contain no meat and are suitable for dogs with common protein sensitivities.
