Description

Protexin Veterinary Pro Fibre Advanced Probiotic and Prebiotic Pellets for Dogs

Protexin Veterinary Pro-Fibre Pellets for Dogs are an easy-to-give probiotic supplement with high-quality sources of soluble and insoluble fibres to encourage normal digestive function, support bowel movements, support gut health and healthy weight management and promote healthy anal glands.

Easy-to-give, artificial liver-flavoured pellets

Using the handy scoop, simply add to your pet’s daily food for as long as needed, or as advised by your veterinary professional. Pellets can also be crumbled onto food if they’re a particularly fussy eater!

Smarter, biotic-powered pet care for a healthier gut

Protexin Veterinary Pro-Fibre Advanced Pellets for Dogs contain the probiotic Calsporin Bacillus subtilis, which helps support a diverse microbiome; while the prebiotic Preplex feeds beneficial bacteria and promotes a healthy, balanced gut.

Supports better digestion and firmer poops

The Calsporin in Protexin Veterinary Pro-Fibre Advanced Pellets for Dogs also encourages normal stool formation, while the addition of prebiotic Fibersol, a good source of soluble and insoluble fibre, also supports better digestion.

Added ingredients for extra immunity

The postbiotic CitriStim acts as a source of mannan-oligosaccharides (MOS) and beta-glucans to support the gastrointestinal immune system and optimise gut barrier integrity. L-threonine amino acid supports the mucus layer – the protective barrier lining their gut.

Ingredients

Pro-Fibre Advanced contains:

  • Soluble and insoluble fibres
    To support normal digestive function and gut health, including Fibersol®, a resistant maltodextrin that is fermented to produce short-chain fatty acids.
  • Calsporin® Bacillus subtilis probiotic
    To support the diverse gastrointestinal microbiome and encourage normal stool formation.
  • Preplex® prebiotics
    To feed and stimulate the growth of beneficial bacteria in the different stages of the digestive tract.
  • CitriStim® postbiotic
    An inactivated yeast (Pichia guilliermondii) acting as a source of mannan-oligosaccharides (MOS) and beta-glucans to support the gastrointestinal immune system and optimise gut barrier integrity.
  • L-threonine amino acid
    Important for the production of mucosal glycoproteins, ensuring gut barrier function and supporting intestinal immunity.
  • Pro-Fibre Advanced is highly palatable with no added wheat.

Protexin Pro Fibre Advanced
Verified Purchase

By Jo Nicholls on 9 July 2026

My 11 year old is having some liver issues. Protexin products have helped him a lot. As he isn’t processing fats as he should his poos have become really sloppy. But this pro-pre/biotic w/fibre has solved this for us. He is also a picky eater so I worried he would reject it, but mixed in his wet food, he’s been fine with it.

I changed my dog to the advanced formula due to a gluten intolerance which he has developed . It suits him well so plan to continue with it.

I have a number of regular deliveries set up with you. However I cannot set up or add Protexin to an existing delivery. Why is this?

Allergies

Dee

Hi does this contain any wheat or glutens

  • VioVet Staff

We have contacted Protexin regarding your query who have advised that whilst none of the ingredients themselves contain gluten, they cannot guarantee there has not been any cross-contamination with other gluten containing ingredients during manufacture. Therefore they can be sure that it is wheat-free, but cannot categorically state that it is gluten free.

Only for dog?

Some of your products are for both cats and dogs. Is this product only for dogs?

  • VioVet Staff

Protexin Pro Fibre Advanced is only intended for use in dogs. If you would like advice on what products you can give your cat then please get in touch at [email protected] along with what you are treating.
