Dogs and cats in the UK can be infected with up to a dozen different types of intestinal worm.

It is not always easy to spot the symptoms, as your vet will tell you, which is why it's best to use Drontal at least every three months to prevent any serious worm infection.

Drontal is the only wormer to kill every type of intestinal worm commonly found in UK cats and dogs – which is why vets prescribe it more often than all other wormers put together!

Most types of intestinal worm which can infect cats and dogs in the UK have the potential to cause serious damage to the animal’s health if left untreated. Remember that some tapeworms can grow up to 5 metres in length – and if that makes you squirm, imagine how your dog or cat must feel!

But even more alarming is the fact that some worms can also infect humans. The dog roundworm (Toxocara canis - pictured right) is probably the best known of these, but there is growing evidence that the cat roundworm (Toxocara cati) can pose a similar threat.

Some of the rarer tapeworms are also a risk to human health – and in every case, it is children who are most vulnerable.

Drontal range

For dogs

Drontal Plus Flavour
For 20 years, Drontal Plus Flavour has been overwhelmingly vets' first line choice of wormer.

Like all Drontal tablets it works with a single dose and can be given with or without food. For dogs the new bone-shape, artificial beef flavour makes it less like a treatment and more like a treat!

Drontal Plus XL
Because a St. Bernard may weigh 20 times more than a Chihuahua, worming big dogs used to require as many as 6 tablets. Not any more! With Drontal Plus XL you can worm a 35kg dog with just one tablet.

Drontal Oral Suspension for Puppies
Unweaned puppies are hardly ever infected with tapeworms, but they are particularly at risk from roundworms, transmitted both via their mother's milk and from other pups in the litter. That's why puppies should be wormed every fortnight, up to 12 weeks of age. With its highly palatable, easily administered liquid formulation Drontal Puppy Suspension is ideal.

For cats

Drontal Cat and Drontal Cat XL
Both will tackle every type of intestinal worm your cat is ever likely to get, and both will do so with a single dose, and without having to starve your cat first. The only difference is that Cat XL Tablets are specially formulated for cats of 4-6kg and over, so that most big cats can be treated with a single tablet.

To avoid worms reaching maturity and affecting your pet's health, and to reduce public health risks, you should worm your pet regularly. Worming at least every three months with Drontal will reduce this risk, but ask your vet who will be able to evaluate your pet's health and your family's requirements and advise you on a specific worming routine for your pet.

Don’t forget the flea control! Fleas are often infected with the larvae of the Flea Tapeworm, which can be transferred to your cat by swallowing the flea while grooming. So in order to control worms, you also need to control fleas. A spot-on treatment is the easiest way to protect your cat – but you may also need one that kills flea larvae in your pet's surroundings, to effectively break the flea lifecycle.

If you don’t control a flea problem at the same time as worming, your cat is almost certain to be re-infected.
