Always consult your veterinarian for specific advice for your dog.

Consistency Is Everything.
Stick with it. Great gut health takes time. Most dogs show their best results around the 3 month mark, so don’t give up early.
Consistency is the key to lasting change.
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.

I know how important gut health is for dogs, so we're now onto our second bag of G Digestive K9. Dixie is 8 months old and training to become a conservation detection dog, with a focus on locating fox dens. Keeping her gut healthy and her body feeling its best is a priority, so she can stay focused on training and perform at her best in the field. We've been really happy with it so far and it's become a part of her daily routine.
Store owner replied: Hi Jade, thank you so much for your wonderful review! We're so happy to hear that Digestive K9 Powder has become part of Dixie's daily routine and is supporting her through her training as she takes on such an important role. Thank you, Berni 💙🐶

My Boy suffers with a constant belly rash and I swear this powder has helped it. He didn’t have this powder for a couple of weeks and the rash came back. I will be keeping him on this forever
Store owner replied: Hi Raelene, thank you so much for your review. It's wonderful to hear that Digestive K9 Powder has made such a positive difference for your beautiful boy. The improvement in his belly rash is amazing. Thank you, Berni 💙🐶
My little rescue doggo Tully has always had skin problems, itchy, dry, flaky and his hair felt waxy. A mess really. I've tried so many different supplements, food, been to multiple vets and tried a number of medications. Nothing made any significant difference until I started Tully on this supplement. His skin is healing, much less flaky, the itchiness is reducing, his hair feels soft and nice to touch, and the smell is gone. I'm actually really blown away with the difference such a short time on this has made. I'll keep buying it for sure .
Store owner replied: Hi Kathryn, thanks so much for your kind review. We're absolutely thrilled to hear Tully's skin is healing, the flakiness and itchiness are settling, his coat is now soft to touch, and even the odour has disappeared. Hearing that he's feeling more comfortable in such a short time is wonderful. Thank you, Jayda. 🐶

My little guy Yuki has had digestive issues for some time , the constant swallowing and licking sound he would make , then he would be outside to see how much grass he could eat to make him feel better . I was buying stress K9 for him as he can get really excited or stressed, but it wasn’t enough so I thought I would try the digestive K9 powder, well the difference in him was almost instant, his been on the powder now for nearly a month and he hasn’t had one reflux episode in that time and his so much happier… no frantic grass episodes either . He has 1/4 scoop on his food at night and doesn’t mind it at all . Definitely be buying more .🐶🐶

Our inner city dog eats naughty stuff often off the street and his tummy pays for his greed by regular runny poos. We started poseidon Digestive K9, 3 months ago and we have been so pleased with the result. Not one nasty, loose yucky poop since we started.
Store owner replied: Hi Pauline, This absolutely made our day to read, thank you for sharing! 🙌 Hearing your pup has gone from regular runny poos to consistent, healthy ones is such a win. It’s great you stuck with it for the 3 months too, giving the gut time to rebalance can make all the difference, and it sounds like your dog is really reaping the benefits now. Thank you, Bec

I highly recommend these as my dog used to eat grass a lot was also vomiting not all the time but sometimes inside not only inside the outside as well, but now he’s a lot happier. I haven’t seen him be sick outside, but I can tell you I have not had any problems with him being sick inside and he’s a lot happier so thank you. I will buy these again because I recommend them and even his poos are better as well so thank you. and can’t wait to buy more as my dog has never been since I bought them for the first time and the Chews are good if you have a fussy dog highly recommend them because I do

My old girl Caviller turned 11 in January and last year she got severe pancreatitis when wecwent away on holidays 😢. Too much anxiety. She has been unable to keep her food down for sometime and has extremely sensitive tummy. When my friend recommended this probiotic she said it was important to have tummy enzymes in it. And after a few weeks of her getting used to it, she now hardly ever throws up. Only when we go out or awayfor the night.🤪 . She is gradually regaining her wait after so long🙏
Store owner replied: Hi Angela, thank you for your lovely review. We’re delighted to hear your girl is feeling better with Digestive K9 Powder. Supporting the gut can make a big difference for dogs with sensitive tummies. Digestive K9 Powder contains our unique blend of prebiotics, postbiotics and para-probiotics, designed specifically for dogs to help support digestion, nutrient absorption and overall gut balance.

So happy with Digestive K9. It’s made a huge difference for Digger! More consistent poos, less grass munching, less ear shaking. And he’s doing way less room-clearing farts! He’s also sleeping better too. He’s had both the powder & the chews - loves them both. Highly recommend!
Store owner replied: Hi Ellie, thank you for such a wonderful review! So glad Digger’s doing better—consistent poos, calmer tummy and ears, and sweeter sleep are wins. Loving both powder and chews—awesome! Thank you, Jess 🐶💙

Our Australian Bulldog rescue is thriving on her K9 chews. We have seen a huge improvement in her skin, teeth and no longer has an itchy smelly rear.

Store owner replied: Hi Nicole, thank you so much for your wonderful review. We’re delighted to hear your gorgeous girl is thriving with Digestive K9 Chews. Thank you, Berni 💙🐶
So happy with Digestive K9. My Frenchie's gut issues have settled down completely and her poops are now normal. It has also worked on our Dachshund. He he allergic to Malassezia, but after taking Digestive K9, his skin doesn't smell and his skin issues have settled down heaps. Would definitely give it a go!
Store owner replied: Hi Tina, thank you so much for your kind review. We’re absolutely thrilled to hear your Frenchie and Dachshund are both doing so well, with settled tummies and happier skin. It’s wonderful to know Digestive K9 Powder has made such a positive difference for them. Thank you, Berni 💙🐶

I love the formula ( retired naturopath/ herbalist) Barkley's overall well being has definately improved. Have bought more & will continue to keep him on it.....great product Highly recommend
Store owner replied: Hi Lesley, thank you for such a wonderful review. We’re so glad Barkley’s overall wellbeing is improving with Digestive K9 Powder—your continued support means a lot. Give him a cuddle from us! 🐶💙
My poor rescue girl has been battling Vet diagnosed allergies, dysbiosis (not sure of spelling) of the gut, itchy ears, hot spots and worst of all, constant licking of her front legs, especially at night. Transition to a good quality food helped, but it took Poseidon chews to actually stop the licking. It took 5 - 7 days for her licking to start to wane and eventually cease. The only downside is that she needs 5 chews a day, which is a slog on the budget. I am going to try the powder instead to get longer relief for her.
Store owner replied: Hi Gai, thank you so much for your review. We’re thrilled to hear your girl is doing so well with Digestive K9 Chews. Digestive K9 Powder is also a fantastic option, especially for larger dogs, as it offers the same great gut health support in a more budget-friendly form. Thank you, Berni 💙🐶

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.DigestiveK9 is designed to support digestion, immunity, skin health, and behaviour.
DigestiveK9 stands apart in three key ways:
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.
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.
Powder Daily Feed Rate
Feed ¼ scoop of powder per 5kg of body weight.
*If your dog is between weights, it is safe to round up. For example, a 7kg dog would receive ½ scoop per day.
Introduction
Introduce slowly over 14 days, starting with ¼ of the recommended serve and increasing gradually. For dogs under 5kg, begin with a light sprinkle of powder.
While some dogs show changes quickly, best results are typically seen after 6-12 weeks of daily use.
Yes! DigestiveK9 is highly palatable. Many owners report their dog won’t eat without it! The powder blends easily with your dog's regular food and is loved by 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.
