Feeding guidelines

  • Small Animal - <10kg - (9ml syringe) - 3ml once a day
  • Medium Animal - 10-25kg - (18ml syringe) - 6ml once a day
  • Large Animal - >25kg - (30ml syringe) - 10ml once a day

If your pet is vomiting, then 12 -24 hours without food will help. After that you should offer bland, easily digested food (fresh cooked chicken or white fish is best, with a little rice for dogs). Ideally the food should be offered in several small snacks through the day. The total amount of food offered should also be reduced. Plenty of fresh water should be available at all times.

55 Perfect for unhappy tummies
Verified Purchase

I've tried alternatives to Promax, but my dogs won't touch it. This they will happily have and it will fix a bad tummy super quick. I always have some in, just in case!

Below are some recent questions we've received regarding VetPlus Promax Syringe for Dogs & Cats, including answers from our team.

Promax large breed 25kg +


Would a 64kg dog still only have the amount that a 25kg dog would

  • VioVet Staff

Yes the >25kg dose is for any dog larger than this, regardless of size.

Duration of Dose

Gillian Taylor

Promax is usually very effective in settling my Havanese's sensitive tummy when she has digestive upsets. How many daily doses can I give her at any time? is it limited to three?

  • VioVet Staff

This product can be used daily in the long term if needed, It is intended for use for short term cases of diarrhoea and should not need to be given more than 5-7 days in a row, as most diarrhoeas will have resolved over this time. If the diarrhoea perists beyond 5-7 days of treatment then I would advise seeing your vet.

Can this be added to food?

Alison Campbell

  • VioVet customer since 2015
  • From: North Lanarkshire, United Kingdom

My cat doesn't seem particularly keen on this and I've had some trouble administering straight into mouth (the plunger is sticking). Can I add it to his food instead and is he likely to notice it if I do?

  • VioVet Staff

Yes Promax can be mixed into the feed if this is easier. If mixed well he is unlikely to notice.

Side effects/ allergy

Carol wilkins

I have given my 7 month old miniature dachshund one dose of the promax. She has come out in lumps on her body and is itching and scratching, could she be allergic to something in this?

  • VioVet Staff

Allergic reactions to a probiotic such as Promax are not common. That said any dog can react in any way to any supplement or medication so it is possible. If she reacts the next time you give it then you can say with more certainty that she is allergic to the Promax. In which case I would suggest trying a different brand such as our own ReguTum.

if cat take too long of the PROMAX, it is harmful for cat's health?

  • VioVet Staff

It is unlikely to be harmful to your cat to take Promax for longer than the specified 3 days course. However if your cats normal digestive functions have not returned within the 3 days it would be best to consult your vet. If you are looking for a long term probiotic you could try Protexin Pro-Kolin Enterogenic.

Can this be given to 6week old pups who are still a bit sloppy from wormimg?

  • VioVet Staff

This is fine to be given to puppies once they are weaned off their mother. Ideally give several small meals per day, but each meal should be a bit less than your puppies would choose to eat. The digestion settles much better if it is not overloaded with too much food, then your puppies will recover faster.
