Pro-Kolin vs YuMOVE Digestive Care: A UK Vet’s Comparison

The difference in Pro-Kolin vs YuMOVE Digestive Care is timing. Pro-Kolin is a short-term paste for a dog whose stools have suddenly gone loose, used for two to three days. YuMOVE Digestive Care is a daily tablet for keeping a sensitive gut steady over weeks and months. Both use the same probiotic strain, so pick by the job.

Pro Kolin, as it is often written, and YuMOVE often sit side by side on the same shelf, and owners understandably assume they are two versions of the same thing. They are not. Pick the wrong one for the job and you will probably be disappointed with either.

Pro-Kolin vs YuMOVE Digestive Care: which one does my dog need?

Choose Pro-Kolin if your dog has had a sudden bout of loose stools in the last day or two and is otherwise bright, eating and drinking. It is meant to be used for two to three days.

Choose YuMOVE Digestive Care if your dog has a sensitive stomach that flares up every few weeks, or you want daily probiotic support for the long run. Neither replaces a vet visit when something more serious is going on.

Prices and pack details come from Protexin's Pro-Kolin Advanced page and the YuMOVE Digestive Support page, and they change often, so treat them as a rough guide.

What is in Pro-Kolin Advanced?

Pro-Kolin Advanced is the updated version of Protexin's original Pro-Kolin paste, and it does three jobs at once. The clays, kaolin and montmorillonite, bind water and help firm up stools. Pectin and psyllium husk add soluble fibre that soaks up excess fluid in the gut.

Then there is a probiotic, Enterococcus faecium, alongside the Preplex prebiotic (fructo-oligosaccharides and acacia gum) to feed it, plus yeast beta-glucans. It all sits in a soya oil base with a liver flavour, which is why most dogs take it straight from the syringe.

The dose depends on weight and is given twice a day. According to the Protexin feeding guide, the 15ml and 30ml syringes give 2ml for dogs under 5kg, 3ml for 5 to 15kg, 5ml for 15 to 30kg and 7ml for dogs over 30kg. The 60ml syringe has its own chart for bigger dogs. Protexin's guidance is to use it for two to three days, or for as long as your vet advises.

The clays are worth understanding. They do not fix whatever upset the gut in the first place. They make the stools more formed while the gut settles, which matters to you and to your carpets, but it can also mask how your dog is really doing. If the stools only look normal because of the paste, stop and reassess after three days rather than carrying on.

What is in YuMOVE Digestive Care?

YuMOVE Digestive Care contains a probiotic plus a large prebiotic blend, with nothing to firm stools quickly. It has recently been renamed YuMOVE Digestive Support Pre & Probiotic, so you may see either name on the box. Each tablet carries 200 million Enterococcus faecium bacteria with three prebiotics that Lintbells calls ActivBio: short chain FOS, MOS from yeast and beta-glucans, according to the YuMOVE product information. Together those prebiotics make up most of the tablet.

It is given once a day. The YuMOVE feeding guide lists one tablet for dogs up to 10kg, two for 11 to 25kg, three for 26 to 40kg and four for dogs over 40kg, from 12 weeks of age, and Lintbells suggests judging results over six weeks. Its job is to keep the gut in a steadier place day after day, which is a different goal from Pro-Kolin's.

If you want the YuMOVE range's answer to Pro-Kolin, look at their Digestive Care Rapid Paste instead. That is the like for like comparison, because it also uses kaolin, pectin and the same probiotic for a few days of use.

Do Pro-Kolin and YuMOVE use the same probiotic?

Yes, and this surprises most owners. A common myth is that the two products use different bacteria, but both list Enterococcus faecium NCIMB 10415 on the label. It is the same strain Purina uses in FortiFlora, where it goes by the name SF68, which I cover in my FortiFlora comparison guide.

So when you choose between Pro-Kolin and YuMOVE Digestive Care, you are not choosing between two different bacteria. You are choosing between a binder paste for a few days and a prebiotic tablet for every day.

Gram for gram, the probiotic content is similar. The paste carries about 200 million CFU per gram and each tablet carries 200 million. The real difference is everything around the probiotic: clays and fibre in one, a larger prebiotic blend in the other.

What does the research say about Pro-Kolin's ingredients?

The best study I know of for this strain was carried out in the UK. Researchers at Wood Green animal shelter gave 773 healthy dogs either a daily synbiotic capsule or a dummy capsule for their whole stay. The capsule contained Enterococcus faecium NCIMB 10415 with Preplex prebiotic, the same pairing used in Pro-Kolin.

By day 14, 18.8% of the supplemented dogs had diarrhoea at least once, compared with 27.2% of the dogs on the dummy capsule. One author worked for the company behind the product, which the paper declares, but the trial was randomised and double blind.

The interesting part is how the supplement was used. It was given every day to prevent problems, not for a couple of days once diarrhoea started. That fits the daily approach better than the short course most owners use Pro-Kolin for.

For the clay, most of the evidence comes from people rather than dogs. A Cochrane review of smectite, a clay closely related to montmorillonite, found it may shorten acute diarrhoea in children by about a day, although the quality of the evidence was low. In dogs, clays have a long history of use in practice, but there is very little trial data. As an MRCVS-registered vet, I see them as a sensible short-term comfort measure, not a cure.

When is Pro-Kolin the better choice?

Pro-Kolin makes most sense for a short, simple upset in an adult dog who is otherwise well. Think scavenged food on a walk, a sudden change of diet, a stressful kennel stay or a day of loose stools after a long car journey.

In those cases a few days of paste, small bland meals and plenty of fresh water are often all that is needed. My guide to dogs with diarrhoea acting fine walks through what to do at home.

It is also handy to keep a syringe in the cupboard if your dog is prone to the odd wobble, so you can start it the same day rather than hunting for something late at night.

When is YuMOVE Digestive Care the better choice?

YuMOVE Digestive Care suits a dog whose stools are often a bit soft, who gets wind easily, or who tends to flare up whenever routine changes. Because it is a daily product, it needs time. Give it at least six weeks before you decide whether it is helping, and keep everything else the same during that time so you can tell.

It is less useful in the middle of a bad day of diarrhoea. There is nothing in it to firm stools quickly, so if you start it during an upset and see no change in a day, that is not a sign it has failed. It simply was not designed for that moment.

When should you skip both and call your vet?

Skip both and call your vet the same day if your dog has blood in the stools, is vomiting as well, seems flat or is not eating, or has a tense or painful tummy. The same goes if they may have eaten something toxic, or are a young puppy, an elderly dog or a dog with an existing health condition.

No paste or tablet should delay a vet visit. Diarrhoea that lasts more than a couple of days, or keeps coming back, also needs a proper look. My guide to dog diarrhoea causes covers this in more detail.

If your dog keeps needing Pro-Kolin every few weeks, that pattern is the important information. Repeated short episodes usually point to something that needs investigating, such as a food intolerance, parasites or a longer running gut condition. My guide to sensitive stomachs is a good place to start.

What if your dog needs more than probiotic support?

Both products focus on a single probiotic strain plus prebiotics or binders. For many dogs that is enough. For dogs whose gut problems tie in with itchy skin, stiff joints or general condition, I prefer a broader daily approach, which is why I formulated Juno Daily the way I did.

It uses a different probiotic, Calsporin® Bacillus velezensis, a spore-forming strain, alongside two prebiotics (chicory root inulin and MOS), postbiotics and slippery elm for the gut lining. For joints it carries Glucosamine HCL, a raw material cartilage uses as it wears, and it covers skin and coat in the same scoop. Juno Daily for gut health is a daily powder rather than a rescue product, so I would still reach for a binder paste on the odd bad day.

You can read more about these ingredient types in my guide to prebiotics vs probiotics, or see how the options compare in my roundup of the best probiotics for UK dogs.

So which should you choose, Pro-Kolin or YuMOVE?

Choose by timing, because these two products answer different questions. Pro-Kolin asks how to get through the next two or three days. YuMOVE Digestive Care asks how to keep the gut steadier over the next few months.

Keep Pro-Kolin for short, simple upsets in a dog who is otherwise well. Choose a daily product, whether that is YuMOVE Digestive Care or a broader option, when the problem keeps coming back.

They even share the same probiotic strain, so the real decision is about the job you need done. If you are unsure which camp your dog falls into, I am happy to talk it through on a free 15-minute call.

Frequently asked questions

Can I give my dog Pro-Kolin and YuMOVE Digestive Care at the same time?

There is no known problem with using them together. Some owners keep the daily tablet going and add the paste for a few days during an upset. As both contain the same probiotic strain, the paste mainly adds its clays and fibre. Check with your vet first if your dog takes any medication.

How long can a dog stay on Pro-Kolin?

Protexin recommends two to three days, or longer only if your vet advises it. If the stools are still loose after three days, or your dog seems unwell at any point, speak to your vet rather than buying another syringe.

What is a good Pro-Kolin alternative?

For a like for like swap, YuMOVE Digestive Care Rapid Paste also combines kaolin, pectin and the same probiotic for a few days of use. If your dog needs paste often, a daily gut supplement and a vet check for the underlying cause make more sense than another syringe.

Is YuMOVE Digestive Care the same as YuMOVE Digestive Support?

Yes. Lintbells has renamed the product YuMOVE Digestive Support Pre & Probiotic. The YuMOVE website describes it as formerly YuMOVE Digestive Care Pre & Probiotic, with the same tablets and dosing.

Do Pro-Kolin and YuMOVE Digestive Care contain the same probiotic?

Yes. Both list Enterococcus faecium NCIMB 10415, the same strain used in Purina FortiFlora. The difference between the two products is the clays and fibre in Pro-Kolin and the larger prebiotic blend in YuMOVE.

Can puppies have Pro-Kolin or YuMOVE Digestive Care?

YuMOVE Digestive Care is labelled for dogs from 12 weeks. Diarrhoea in a young puppy can become serious quickly, so please call your vet before giving any product, especially if your puppy is not fully vaccinated.

Which is better for stress diarrhoea?

For a one-off episode, such as after kennels or a house move, Pro-Kolin is more practical because it firms stools over a few days. If routine changes always cause loose stools, start a daily product a few weeks before the known trigger. My article on whether stress causes diarrhoea explains why.
