How often should I worm my dog?

It’s important that we don’t wait to see signs of worms or ill health before worming our dogs. Regular worming is part of responsible dog ownership to protect our pets, ourselves and others. How often a dog should be wormed depends on a number of different factors. Experts recommend treating dogs for intestinal worms at least four times a year. However, more frequent treatment may be needed in certain cases, for example if you have children, if there are pregnant women, elderly or immunosuppressed individuals in the home, or if your dog has had fleas. Always follow the advice of your pet healthcare professional who can recommend the frequency that works for your dog’s circumstances.

How does my dog get worms?

There are 4 common ways your dog can pick up intestinal worms:

  1. By swallowing infected fleas while grooming. If you’re unsure if your dog has fleas, there are some common signs of fleas to look out for
  2. By ingesting worm eggs from a contaminated environment (for example, toys, grass or soil)
  3. By eating or scavenging carcasses of other infected animals (for example, mice, rabbits or birds)
  4. From the mother to her puppies, either across the placenta before they’re born, or via her milk when nursing.

How do I know if I need to worm my dog?

We shouldn’t wait until we start seeing signs of worms before giving worming treatment to dogs, because infections don’t always show signs until they’re severe. Signs of worms can include weight loss, a bloated tummy, diarrhoea, vomiting and dogs scooting their bottoms along the ground (but these signs are not specific to worm infections – they can indicate other issues). Read more about why worming your dog is important and the risk of not doing so.

Worm eggs are microscopic, but you might see worm segments (looking like grains of rice) in your dog’s stool or around their bum. Find out more about the symptoms of worms in dogs.

Can people catch worms from dogs?

Yes, people can get infected by some worm eggs present on their dog’s fur or in the environment, which can cause serious diseases. Roundworm larvae can travel through the body and cause blindness in severe cases, especially in children. That’s why it’s important to worm your dog regularly, even if you can’t see any worms or your dog looks healthy. Regularly using dog worming tablets can help reduce the risks and protect your whole family.

Is my dog more at risk from worms at certain times of the year?

No, dogs can pick up worms at any time throughout the year. Worm eggs can survive in the environment for several years and infect your dog anywhere they explore.
