How often should I worm my dog?

Research has shown that the majority of dogs in the UK should be wormed monthly, based on their home environment and lifestyle such as scavenging, spending time outdoors off their lead and even access to back gardens.* However, there may be situations where less frequent treatment is required and it’s best to speak to your vet about the most appropriate worming frequency for your dog.

Below is a guide to help assess the most appropriate treatment frequency for your dog:

Not that tasty
Verified Purchase

By Sally McSorley on 23 September 2026

My dog will normally eat absolutely anything, he is very greedy, but I have to disguise this because he won't eat it like a treat, so it can't be that tasty (as it is described!). I can't comment on whether it works, but I give it as a preventative measure. Hopefully it is doing its job.

Frequency of worming

Justine

How often should this be given to my dog? And should the same wormer be used or alternate with another?

We recommend worming dogs every 3 months.

How much

Claire Stolber

  • VioVet customer since 2021
  • From: Bedfordshire, United Kingdom

My dog weighs 58kg, how many tablets do I need to give him?

  • VioVet Staff

Your 58kg dog can take either of the following doses:
2 x Drontal XL (1 per 35kg) tablets.
OR
1 x Drontal XL (1 per 35kg) tablet AND 2+1/2 x Drontal (1 per 10kg) tablets.

The latter dose is preferred as this is more accurate for the weight. However, either are permissible through the datasheet.

Can I split an XL tablet for a smaller dog?

Dee

  • VioVet customer since 2020
  • From: , United Kingdom

I have several unopened Drontal XL tablets for dogs >35kg, bought for our older dog, who has sadly died. We have adopted a much smaller dog: 18.7kg. Would it be ok to give him 1/2 an XL tablet, or would that not give him enough medication? I know we would then have to throw the remaining half tablet away as they don't last long after opening.
Thanks

  • VioVet Staff

The datasheet for this medication advises that dogs weighing approximately 17.5kg can be given half a tablet as one dose. It also states to give a dog between 20kg and 35kg one whole tablet.
Your dog is slightly inbetween these dosing guidelines unfortunately. You can safely give half a tablet but it is a slight underdose which may mean your dog is not wormed completely effectively. However it is only very slight and so unlikely to make a significant difference. We can only advise as per the datasheet though so would recommend using 2 x Drontal (1 per 10kg) tablets for your dog instead.

What does Drontal treat

Chris Jaron

What type of worms do these tablets treat

  • VioVet Staff

Drontal treats roundworms and tapeworms. If you are based in the UK then the only worm you need to consider that it does not cover is the most common cause of canine lungworm. Only prescription products containing either moxidectin or milbemycin will cover this.

Treats up to 35kg of bodyweight but datasheet is incorrect

Jason Morris

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

can you explain why it says Each tablet will treat up to 35kg of bodyweight but the data sheet contradicts that and says > 15-20 2

So what one is wrong?

  • VioVet Staff

The datasheet is a combined datasheet for Drontal Tasty Bone Wormer Tablets (1 per 10kg) and Drontal XL tablets (1 per 35kg). It is likely you are reading the smaller tablet section, I recommend reading further on. You are right, Drontal XL is 1 tablet per 35kg.

How many tablets

Jacqui luck

My dog is a mastiff x rottie would one tablet be enough for her as it says up to 35 kg and she's about 40 + roughly thanks

  • VioVet Staff

It is advised to give your 40kg dog 1 x Drontal XL tablet (1 per 35kg) and 1/2 x Drontal Tasty Bone Wormer tablet (1 per 10kg), this will total a dose for a 40kg dog.

Dog refuses to eat

Hilto

  • VioVet customer since 2009
  • From: Merseyside, United Kingdom

I have tried giving tablet, whole, broken up and crushed, still leaving it. Been mixed with cheese, food - no effect. Any suggestions?

  • VioVet Staff

These tablets can be crushed into a powder if needed. It is recommended to try doing this and mixing it with very palatable food, such as liver pate.

Drontal

VioVet Visitor

I have given my dog 1 xl drontal tasty bone to treat giardia, but I'm not sure if this is effective enough to kill the parasite? As I believe it should be given once for 3 days, I don't want to overdose my dog who's a German shepherd. I know usually it's given every 3 months. I know panacur is also effective, but I've already given her the drontal so I know I can't give her another dewormer on top of what she's already had, as I know how to administer panacur, but completely forgot about panacur. Can I give her any more drontal? Or will the one be effective enough to kill the parasite?

Thank you in advance.

  • VioVet Staff

Drontal is not licensed to kill Giardia however there is an off license dose that your vet can advise you on. We unfortunately cannot provide off license dose advice so you will need to discuss this with your vet. I apologise that we cannot be of much help.
