PreproFlex Advanced™
Premium Triple Action Digestive Support Powder For Dogs
Support starts in the gut. PreproFlex Advanced combines prebiotics, probiotics and postbiotics in one expertly formulated daily supplement to help maintain normal digestive function, support a balanced gut microbiome and contribute to your dog's everyday wellbeing.
Whether your dog has a sensitive stomach, is changing diets or simply deserves daily digestive support, PreproFlex Advanced delivers premium nutrition with every scoop.
Healthy Gut. Happy Dog.
A healthy digestive system plays an important role in your dog's everyday wellbeing.
PreproFlex Advanced has been carefully developed to provide layered digestive support using three complementary approaches:
- Prebiotics to nourish beneficial gut bacteria.
- Probiotics to introduce beneficial bacteria.
- Postbiotics to help support a balanced gut environment.
Combined with carefully selected ingredients including pumpkin, clinoptilolite, bentonite and a canine authorised probiotic strain, PreproFlex Advanced delivers comprehensive digestive support in one simple daily supplement.

Recommended to me by a nutritionist for a dog getting a sicky tummy. We’re 2 weeks in and so far all good 👍
Seems to be doing my dogs health a lot better
This has really settled my dogs tummy
My dog is a fussy eater so I thought he wouldn’t eat his raw meals as he’s very clever he always knows when there is something added to his meat lol, but no he’s eating his meals with the powder in it he’s been on it a week now and he seems brighter in himself
Great product from a great company. I've used these products for a few years. Always fantastic customer service and can't fault the products, they're excellent quality and value for money.
