Protexin CystoPro has been developed to encourage urinary tract health. Infections may occur when bacteria attach and multiply along the urinary tract. CystoPro contains an active ingredient derived from cranberries which is in a class of antioxidants called Proanthocyanidins (PACs). CystoPro also contains probiotics, prebiotics and N-acetyl D-glucosamine. CystoPro combines 4 innovative ingredients and is chicken flavoured to increase effectiveness and palatability.


  • Proanthocyanidins (Type A PACs) - Proanthocyanidins are naturally occurring powerful antioxidants extracted from the North American cranberry. Type A PACs have been shown to inhibit the ability of E.coli to attach to the urothelium, thereby preventing bacterial adherence, colonisation and infection
  • Probiotic - The EU-registered strain Enterococcus faecium (NCIMB 10415) E1707 acts to reduce pathogenic bacteria within the gastrointestinal tract thereby reducing the risk of ascending UTIs of faecal origin
  • Mannan-oligosaccharide - Created from purified yeast cell walls, Mannan-oligosaccharide (MOS), binds E.coli and upregulates the innate immune system by attracting phagocytes to opsonise the bacteria. MOS is commonly used as a prebiotic to support intestinal microflora
  • N-acetyl D-glucosamine - N-acetyl D-glucosamine is a precursor to Chondroitin sulphate and Keratin sulphate which make up the Glycosaminoglycan (GAG) layer that lines and protects the sensitive bladder urothelium. A strong, resilient GAG layer prevents bacteria from adhering to the urothelial cells
  • Artificial Chicken Flavour - To improve palatability and compliance

Below are some recent questions we've received regarding Protexin CystoPro for Dogs, including answers from our team.

Can this be used as a preventive measure against urinary stones in

Elizabeth Gray

  • VioVet customer since 2017
  • From: Durham , United Kingdom

Can this be used as a preventive measure against urinary stones in A Dalmatian that had recently had a U.T.I but has not been diagnosed as being a stone former?

  • Veterinary Advisor

This supplement will help promote good overall urinary tract health and may help prevent UTIs in the future but it is unlikely to stop your dog forming Urate stones. I would recommend a low purine diet such as Royal Canin Canine Veterinary (Clinical) Diets Urinary U/C UUC 18 Low Purine Dog Food as the best thing to help prevent stones.

Ear infection


Will these work for a dogs ear infection

  • Veterinary Advisor

This product is specifically formulated to combat urinary tract disorders so will likley have no effect of helping with an ear infection. I would recommend something such as TrizAural which is formulated for ears.


Ear infections can be tricky to treat so don't hesitate to visit your vets if you feel you are not winning with non prescription treatments.

When to use product


I wonder if you can tell me if this is an ongoing treatment everyday or do you use this product when signs of a uti are occurring, our 10 year old siberian husky is prone to uti's since a mistake at our vets few years back and usually gets baytril to get rid of uti,but I'm looking at options to help him control this by trying to keep bacteria at bay and eliminating the possibility of further uti's. Many thanks Mark!!!

  • Veterinary Advisor

Protexin advise that CystoPro can be given for as long as necessary. Looking at the ingredients I can't see any reason why it shouldn't be given long term and should be perfectly safe given daily. It is difficult to predict but CystoPro may well help to prevent further UTI's in your dog so would certainly be worth a try.

Is it affective for a urine infection

Julie Wilkins

  • VioVet customer since 2016
  • From: West Midlands, United Kingdom

My 12 yr old Doberman bitch is in her 2nd week of season and she's drinking a lot and weeing a lot more she even weed in the house which she's disgusted in herself for lol but other than that she dnt seem ill she's eating drinking sleeping the same her nose is cold so I'm wondering if these will help her as taking her to the vets stresses her out so much I've orderd one lot of these pills anyway I'm just waiting for them to arrive

  • Non-Executive Director

My main concern would be that your bitch is developing an infection in her uterus (womb). This is even possible if she has been spayed, though is much less likely. I would have to say that the best thing would be to take her to the vet for a check over. This would become very important if she goes off her food, vomits, or has any sort of abnormal vaginal discharge. You might be right that this is a problem which will pass by itself in time but there is a distinct possibility she is starting to become ill. If so, the sooner this is acted upon, the better the chances of a successful outcome. Uterine infections can be very serious.

What's this medication protein levels?

Leon Wilson

  • VioVet customer since 2015
  • From: Caerdydd, United Kingdom

Is this product suitable for a dog that has a liver shunt and is on a low protein diet?

  • Non-Executive Director

There is very little protein in this product and it should be perfectly safe for your dog if given at the normal rates.

Is it for incontinence


My 14 year old dog as incontenance will this capsule help him

  • Non-Executive Director

There is a chance that it will help, but it is unlikely to be the complete answer. There can be a combination of reasons why elderly dogs become incontinent, but ascending bacterial infections are sometimes a secondary consequence of the underlying problem, which then make it worse. This product can help with some aspects of bacterial infection and so can help limit the extent of that part of the problem. Essentially it would be safe to try them and see if they help. They might do, but are unlikely to be a complete answer.

Michelle Forrest

When is the best time to take cystopro and can it be taken with gabapentin

  • Non-Executive Director

This product has not been specifically tested for use along with gabapentin, but it is very unlikely that this combination will result in any additional risk of adverse reaction.

One dose of Cystopro is effective for up to 24 hours so the timing of the dose is not important, as long as it is given regularly at about the same time of day.

27 January 2015 at 2:09pm

Can this be used with other products?


My dog is currently taking Cystaid, can he take this product at the same time?

  • Non-Executive Director

These products can be given at the same time and this should be safe. The CystoPro might well help your dog but that is difficult to predict and depends partly on the underlying cause of the problem. You can safely try it and see.

Cat with recurrent cystitis


  • VioVet customer since 2014
  • From: Merseyside, United Kingdom

can this item be used for cats,
my cat is 6 years old and suffers from stress related cystitis she has about 3 or 4 bouts of cystitis a year,i have tried cystease and cystophan as recommended by my vet but she still has recurrent cystitis

  • Non-Executive Director

This product is very unlikely to help your cat as it is aimed at treating a completely different type of cystitis (as well as being intended for dogs).

The best advice in my opinion would be for you to change things so that your cat takes in more water and hence produces more dilute urine. The recurrent cystitis your cat suffers from is virtually unknown in cats producing dilute urine. There are a number of ways to try and achieve this, including leaving water in glass or ceramic bowls, in 2 or 3 places dotted around your house. On window sills is often a good place. Cats tend to like to drink water they come across around and about. (Hence puddles, ponds and bird baths are usually much more appealing than the bowl in the kitchen.) You can even buy a running-water fountain type drinker, which encourages some cats very effectively. (There are some on our website.) However probably the best thing to do, perhaps in addition to some of the above, is always to give food with a high water content. This means stopping all dried foods and using wet foods which have a significant gravy or jelly content. You can even add a little fresh, luke-warm water to the wet food to make it even more watery. Cats on a diet like this with no dried food are pretty much entirely free of cystitis for ever, though it is not nearly as convenient as the dried foods...

Diabetic 11 year old dog

Sian-Marie Jenkins

Is this suitable for a diabetic bitch who has recurrent cystitis? She is 11 years old

  • Non-Executive Director

Diabetic dogs are very prone to cystitis and this product can certainly be given to help. It should not be a problem for the diabetes at all.
