I took my dog to the vets in December 2019 with chronic diarrhoea. The vet saw him and gave him half a dozen Digestive Support and a tube of pro-biotics without prescribing any drugs. Obviously, the digestive support and pro-biotics was only a temporary fix and his diarrhoea came back on and off for months after. His tummy started to bloat (with loud gurgle) and produced smelly farts. He started to vomit bile when that happens.
I contacted the vets again and it was suggested that I allowed them to do a poop test when I phoned them again in early May 2020. The dog's tummy got better after that phone call so there was no point doing the test then.
All this time, my dog's breath reeked really bad and someone thought it was his oral hygiene but I ruled it out as I was brushing his teeth daily.
My dog's tummy suddenly took a turn again on 20 July 2020 and this time the diarrhoea came back with a vengeance.
I did some research online and thanks to a load of very helpful resources online from experienced dog owners and vets, from his symptoms, I came to the conclusion that he is suffering from the nematode parasite known as Giardia.
I spoke to the vets again on 21 July and they refused to sell Panacur to me and insisted that I allow them to do a poop test. I knew it was going to be expensive and a time consuming process (I lost a dog previously because they had been messing me around too much) and diagnosis would be a hit and miss with the vets. I decided to take matters in my own hands and looked online to purchase this drug. Thankfully, I found it on Viovet and ordered it on 22 July 2020. It arrived on 25 July and and I started my dog on it immediately at 12 noon that day.
The diarrhoea carried on and was particularly bad on the early hours of morning on 27 July when I was woken up three times by the dog begging to go out to toilet. By the third dose on 27 July at 12 noon, like magic, the dog's tummy suddenly took a turn and the diarrhoea stopped after 3pm. This morning, 28 July, he produced a beautiful solid poop for me and I can tell you I was well pleased. His diarrhoea has not returned. His breath is no longer reeking of terrible odour and he is a happy dog!

I have started him on another product (ProKolin Advanced) which will help boost his digestive tract flora and bring his health back to speed. I will now have to bath the dog and wash everything in the house thoroughly. I would repeat of Panacur in 3 weeks' time to ensure that his system is 100% cleared of Giardia.

Caveat: My dog is MDR1 genetic deficient and he used to have Panacur paste for deworming as a puppy so I knew that he is not allergic to this drug. You need to be cautious when using this drug for the first time. Please follow instructions given in the leaflet and I find giving the drug for 3 consecutive days is good enough to eliminate Giardia even for extensive prolonged gut infestation as with my dog. There is no need to double the time to 6 days as some websites suggest.

Bottom line: Please pet owners, pay close attention your dog's breath. It shouldn't reek or have bad doggy breath cos if your dog has bad doggy breath, he is either ill or has dental problems.

Panacur liquid

Lynette Ayres

  • VioVet customer since 2016
  • From: Gloucestershire, United Kingdom

How much would l give to a tiny dog about 6lb in weight

  • VioVet Staff

6lb is roughly 2.7kg so the practical dosage recommendation at this weight is 4mls at a single oral dose for routine treatment. It is advisable to repeat this around 4 times a year. However dosing is increased for specific infections such as control of lungworm which requires dosing at 1 ml per 2 kg bodyweight daily for 7 consecutive days.

8 August 2016 at 7:58pm



Please can you tell me how many ml each puppy needs at 2week, 5week and then 7weeks.

  • VioVet Staff

Hi Rebecca,

The amount each puppy will need will depend on their weight, so you will need t o weigh each puppy before treatment, and give the appropriate ml per kg bodyweight.

The recommended dose is 0.5 ml per kg bodyweight daily for 3 consecutive days. If your puppies weigh 2kg at 2 weeks, they would need 1ml daily for three days.

Full dosage instructions will be included in the packaging, and can also be found on our website in the description tab below the listing. I hope this helps!

Safe to treat rats


Hi I just got 4 baby rats who need worming they have round bellya and looks as if their soft poop has white bits in is this product safe to treat them

  • VioVet Staff

It is unusual for rats to need worming though this is possible. Strictly speaking since Panacur is licensed for use in dogs and cats, if you want to use it in rats, this decision should be taken by the vet who is in charge of their care. However Panacur is in fact a very safe wormer if given at the correct dose according to body weight.

How many doses

Louisa McKitten

  • VioVet customer since 2016
  • From: County durham, United Kingdom

I have been prescribed panacur 10% 0.4mg for my 3 year old horsfield tortoise. Im wondering if i have to repeat the treatment in 10 days or will this be a one off dose

  • VioVet Staff

I wonder how you are going to administer this as it is not easy to stomach tube this species. Giving with food is not very reliable at all. Assuming you are successful, it is normally a one-off dose for routine worming. Some people advocate giving just one third of the dose daily for 3 days, to reduce the chances of toxicity to the tortoise and to increase the effectiveness of the worming dose. Most people do just give a single dose however. Ideally you should check with the vet who prescribed this.

Giardia Panacur Granules Panacur Oral Suspension/Liquid


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

Hi. Wondering if you can help me? I have a 40kgs GSD. What is the dose of Panacur Granules/Oral Suspension/Liquid to treat Guardia?

  • VioVet Staff

For the treatment of Giardia spp. infections in dogs using 10% suspension, administer 1 ml per 2 kg bodyweight daily for 3 consecutive days (= 50 mg fenbendazole/kg bodyweight daily for 3 days).

For your dog this means 20mls per day for 3 days.

Panacur oral suspension

Sarah q

I was told today by my vet that this only works against lungworm in cats.! I understood it to be for dogs and cats! I'm confused

  • VioVet Staff

In a way you are both correct. This is a very good wormer for many different species of animal, including dogs and cats. However it is not able to kill every type of worm in every species. In the cat it is effective against the usual cat lungworm, along with the worms which live in the gut. In the dog it is effective against the worms which live in the intestines and for one type of lungworm. However the lungworm which is the biggest concern for dogs and is in the news a bit at the moment is not effectively controlled by Panacur at all. A different wormer has to be used in dogs if this worm (Angiostrongylus vasorum) is a concern.

Lungworm treatment

Brenda Needham

My dog is regularly wormed with panacur,which I understand doesn't protect him from the lungworm passed on from slugs.He is a border collie and and I dont want to put advocate on him.
So if he ever picked this worm up,what would the treatment be.?
I have been told advocate is not safe on some breeds.So I do worry about the whole thing.Lungworm has affected a few dogs in the area.(Kent)

  • VioVet Staff

The only product which is known to be effective against the type of lungworm you are concerned about is indeed Advocate. This belongs to a group of drugs which Collie types are known to be particularly sensitive to. However as long as you give Advocare at the recommended dose, it seems to be very safe for Collies and I would not worry about that, it is only a problem if they are accidentally over-dosed, which of course you should not do anyway.

15 January 2015 at 9:30am



Does it kill lungworm?

  • VioVet Staff

The answer is yes and no. There are different types of lungworm and it is possible to kill them at different stages of their development, all of which have an impact. Panacur will kill the type of lungworm called scientifically Oslerus (or Filaroides ) osleri. However this lungworm is not a big deal in dogs and killing it is not hugely important. The type of lungworm in the news at the moment is a completely different creature. Called scientifically Angiostrongylus vasorum, it is NOT treated effectively by Panacur and you cannot rely on it to look after your dog regarding this lungworm. Therefore it is true to say that Panacur kills lungworm, but that is missing the point. It is not what you want. The most effective treatment appears to be the prescription product Advocate, which kills lots of parasites including, the lungworm you are probably asking about. Sometimes life is not simple!

Panacur for snakes

Ayoub Sayed

how much (ml or mm in the syring) panacur i have to give an adult rat snake and for how many days or for how long.

  • VioVet Staff

You will need to know the weight of your snake first. Then if you are using the 10% Panacur suspension, you should give 0.5mls per kg bodyweight of snake. Repeat this in 2 weeks, then again 2 weeks later. If you use a 1ml syringe, then often these are graduated in one hundredths of a ml, so it would be the 50 mark on the syringe for a 1kg snake, or 1 unit on the syringe for every 10g of snake. If in doubt, you should talk to your vet about this. Unless we are given a prescription from your vet, as an online supplier we can only sell this product for use in dogs and cats due to licensing regulations. Your vet can prescribe it for reptiles and other animals.
