Protexin Pro-Kolin Advanced for Dogs: Review
PawPicked is reader-supported: we may earn a commission from links on this page.
Pro-Kolin Advanced is the paste people reach for when a dog's stools have gone soft, and it is best understood as a short-term digestive support product rather than a daily supplement. The listing sells it as a way to provide biotics support for the gut, soothe the gut lining, firm up runny poos and support the immune system. Before buying, it helps to know what that means in practice and where the product's limits are.
What the label lists
The 30ml Protexin Pro-Kolin Advanced paste comes in a syringe, with a dosage wheel on the plunger. The ingredients and functions named in the listing are:
- Enterococcus, the probiotic, said to promote good bacteria in the gut microbiome.
- Preplex, a prebiotic, described as feeding those bacteria.
- Pectin, another prebiotic, said to soothe the gut lining.
- Psyllium, a soluble fibre, which the listing says promotes intestinal transit time.
- Kaolin and montmorillonite, natural binding agents that the listing says help firm up faeces.
- Beta-glucans and taurine, listed for immune support.
This is a combination product. Some of the ingredients work as bulking and binding agents, and the others are the biotic and gut-lining parts. That mix is what separates it from a plain probiotic powder, and it is why some owners associate it with loose stools in particular. The ingredients section of the 30ml listing is mostly blank, so the exact amounts are not on the page; check the pack.
Format and dosing
The paste is described as artificial liver flavoured, and the listing says the dosage wheel on the plunger makes it easy to give the right amount up to three times daily. We don't give amounts here because the listing doesn't state a dose per dog weight, so follow the manufacturer's instructions on the pack or your vet's advice. The syringe makes it simple to measure, and the pack will say how it is meant to be given.
Storage is straightforward: store somewhere cool and dry, clean the syringe after each use and replace the cap. On very hot days without a cool spot, the listing says it can go in the fridge. The listing also notes soy may be present.
The 60ml listing
There is also a 60ml pack of the same product, listed as Protexin Veterinary Pro-Kolin Advanced for Dogs with a syringe included. Its listing is notably different in places: the specification gives the flavour as unflavoured, while the 30ml page says liver. That is an inconsistency between listings, so check the packaging before buying if flavour matters to your dog. The 60ml listing says the product has a two-year shelf life from manufacture and that, stored properly, it lasts to the best before date even after opening, which is useful if you want to keep a spare in the cupboard.
Ratings on Amazon.co.uk at the time of writing: 4.7 out of 5 from 12,651 ratings for the 30ml, and 4.7 out of 5 from 6,445 ratings for the 60ml. Cost per day depends on how much you give and for how long, so divide the pack price by the days it lasts, and check the current price on Amazon for both sizes. A larger syringe makes more sense for an owner who expects to use it often, or for a large dog.
Drawbacks
- It is not a long-term product. The listing focuses on firming stools and soothing the gut, which suits short-term use, and the listing gives no guidance on long-term feeding. Ask the vet if you are tempted to use it regularly.
- It masks the cause. If loose stools keep coming back, the paste may firm them without explaining why they are loose.
- Taste. The liver flavour is described as one dogs love, but that is the listing's claim, and a fussy dog may refuse it.
- Soy. The 30ml listing notes soy may be present, so check it if your dog is sensitive.
- Limited detail. Quantities of the active ingredients aren't shown on the pages we saw.
When to see a vet
A paste can sit alongside veterinary advice, not replace it. Contact a vet if diarrhoea continues for more than a day or two, if there is blood or black stool, repeated vomiting, a swollen belly, lethargy or refusal to drink, or if the dog is a puppy, elderly or already unwell. Puppies and small dogs can become dehydrated quickly. Our dog diarrhoea guide sets out what to do at home and when to call. This review is general information and not a substitute for a vet's examination.
What we would pick
Pro-Kolin Advanced is a sensible thing to have in the cupboard if you want a vet-brand paste with a measured syringe, and your vet is happy for you to use it for the odd upset. Choose the 30ml to try it, and the 60ml if you expect to use it more. It is a poor fit for a dog with a soy sensitivity, for anyone hoping for a daily maintenance supplement, or for a dog whose digestion is repeatedly upset. In those cases, see the vet first, and read our comparison of powder and paste probiotics to see whether a different format suits better.
