Unfortunately, there is no tablet or injection you can give a dog which will prevent worm infection. The best you can do is to kill any worms which may be present, on a regular basis. To avoid worms reaching maturity and affecting your pet's health, and to reduce public health risks, you should worm your pet regularly.
Worming every three months 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.
There are three Drontal wormers for dogs
Drontal Plus Flavour
For 15 years, Drontal Plus has been overwhelmingly the vet's first-choice wormer, prescribed well over twice as often as all other wormers put together.
But now, it has been succeeded by NEW Drontal Plus Flavour - the same power, the same effectiveness, but now with an appetising chicken flavour.
Like all Drontal tablets, it works with a single dose, and can be given with or without food. In fact it still gives you all the advantages of Drontal Plus. But for dogs, the new chicken 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 35 kg dog with just one tablet.
Drontal Puppy Suspension
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. And with its highly palatable, easily administered liquid formulation, Drontal Puppy Suspension is ideal.
Drontal: the hardest working wormer
Drontal Plus' unique combination of proven active ingredients enables it to tackle roundworms, tapeworms, hookworms and whipworms – in fact, every type of intestinal worm your dog could normally get in the UK.
Roundworms
Tapeworms
Whipworms
Hookworms
Toxocara canis
Dipylidium caninum
Trichuris vulpis
Uncinaria stenocephala
Toxascaris leonina
Taenia spp.
Ancylostoma caninum
Echinococcus granulosus
Echinococcus multilocularis
Treatment tips
Most dogs are not fussy eaters, and will readily swallow a tablet with their regular meal. (Unlike cats, who seem to be born with an inbuilt tablet detector!)
But there are always exceptions, and if your dog is a reluctant tablet-taker, you could try wrapping the tablet in a favourite treat, or coating it with butter. (Most dogs like butter, and it also helps the tablet to slip down easily.)
Don’t forget the flea control!
Fleas are often infected with the larvae of the Flea Tapeworm, which can be transferred to your dog 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 dog – but choose one that not only kills adult fleas on your pet, but also kills flea larvae in your pet's surroundings, to effectively break the flea lifecycle.
If you don’t control a flea problem, worming will be a waste of time, because your dog is almost certain to be re-infected.
