How Often Should I Worm My Dog?

Worms are intestinal parasites that can live in a variety of animals. Some worms will only affect certain animals, and others will affect a few different animals. Some worms can also affect humans.

There are four common types of intestinal worms in dogs:

  • roundworms
  • hookworms
  • whipworms
  • tapeworms

Symptoms of infection, as well as the way the worms are picked up, can vary. This is why it is really important to ensure that your dog receives regular worming treatment.

From infection through fleas, to through contact with the faeces of another dog on a walk, there are potential dangers in your dog’s everyday life everywhere.

What is a dog wormer?

A dog wormer is a medication that can either prevent the infection of worms, treat an infection of worms, or both. The practice of removing or preventing worms in dogs is called ‘worming’.

The majority of over the counter worming medications are purely used as a preventative. But there are stronger options out there that can rid your dog of infections. For more severe cases, veterinarian prescribed medication will be needed for treatment.

Dog wormer can come as a tablet, liquid, or granules that are sprinkled on food. There are also pastes available for younger dogs. Which is best for you depends on whether your dog happily takes medication and the risk of worms to your dog.

How often should I worm my dog?

If we are talking about preventing worms, most tablets must be given one every three months. All medications have instructions on the back that must be followed, and three months is the general consensus.

However, depending on your dog’s lifestyle, a vet may recommend for worming treatment to be taken more regularly than this, particularly if it is a paste or liquid which is not as strong. It may even be better for your dog if they have a stronger tablet once every six months.

For the treatment of worms, again this may be more regular, such as a very strong tablet once per month if your dog’s stomach can handle it.

Never worm your dog more often than the recommended dosage before asking a vet.

How can I prevent my dog from getting worms?

As mentioned, regular worming treatment is vital for the prevention of worms. Don’t leave it until your dog has worms and you have to use wormer as a treatment.

All dogs will actually carry worms almost permanently. When using a wormer, not all worms will be removed. It just prevents the worms from being a burden and taking over, which can make your dog really ill. So regular prevention treatment is so important for maintaining your dog’s balance of worms.

If you have several pets, it is important to worm them all. This includes both cats and dogs – some worms can be passed amongst species.

Can I worm a dog too often?

Yes, it is possible to worm a dog too regularly. Because the wormer releases chemicals which has an effect on a dog’s gastrointestinal system, they could become overwhelmed by the medication.

This can lead to sickness, diarrhoea, and other internal illnesses such as nausea. While it shouldn’t lead to them being permanently ill, it serves them no real benefit.

When a wormer is used, worms are paralysed and killed before being excreted through faeces. Waiting around three months before a repeat dose should give their body enough time to recover while keeping on top of any repeated infections.
