Beaphar One Dose Wormer For Large Dogs

SKU: 516266
  • Adult dogs should be wormed routinely every 3 months. The most common tapeworm of the dog is transmitted by the flea, so attention should also be paid to flea control. It is important to worm puppies very regularly for roundworm at 2 weekly intervals from the age of 2 weeks to 8 weeks. Worming should then be carried out at 12, 16 and 24 weeks of age. Thereafter, the adult regime of 4 times per year is recommended. Nursing females should be treated at the same time and as frequently as puppies up to 12 weeks of age.


    Tablets should be given whole with about one fifth of the daily food ration in the morning when the dog’s stomach is empty. The remaining food should be given in the evening. 


    Weigh your pet before treatment to accurately establish the correct dosage. You can do this by weighing yourself, and repeating whilst holding your pet, on the bathroom scales. The difference is the weight of the dog. 




    It is important to follow the instructions carefully. For routine treatment of puppies and adult dogs, give one tablet per 10kg (22lbs) bodyweight. The following table provides a dose guide:


    Dog's Weight

    6.1 - 10kg - 1 tablet

    10.1-20kg - 2 tablets

    20.1 - 30kg - 3 tablets

    30.1 - 40kg - 4 tablets


    For dogs weighing more than 40kg (88 lbs), give one additional tablet for every extra 10kg (22lbs) in weight. For dogs weighing less than 6.1kg (13.2lbs), use Beaphar One Dose Wormer for Small Dogs and Puppies.

  • Warnings: These tablets are film coated and should not be broken or divided. If you are unsure about dosing your pet, speak to your Veterinary Surgeon. When administered as recommended, tablets are unlikely to cause vomiting.  If vomiting does occur, do not repeat. If signs of disease persist or appear, consult a Veterinary Surgeon.
