Drontal Plus XL Worming Tablets - You can worm a 35 kg dog with just one tablet. Unfortunately, there is no tablet or injection you can give a dog which will prevent a 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, you should worm your pet regularly - this will also reduce public health risks.
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.
