1 ml per 1 kg bodyweight as a single oral dose (= 100 mg fenbendazole/kg bodyweight).

Practical dosage recommendations:

For dogs weighing over 64 kg, an extra 1 ml is required for each additional 1 kg bodyweight.

The dose should be mixed with feed, or administered orally directly after feeding.

Treatment should be repeated when natural reinfestation with parasitic worms occurs. Routine treatment of adult animals with minimal exposure to infection is advisable 2 to 4 times per year. More frequent treatment at 6 to 8 weekly intervals is advisable for dogs in kennels.

0.5 ml per kg bodyweight daily for 3 consecutive days given by mouth after feeding to unweaned animals or mixed with food for weaned animals (= 50 mg fenbendazole/kg bodyweight daily for 3 days).

Practical dosage recommendations:

For puppies weighing over 10 kg, an extra 0.5 ml is required daily for each additional kg bodyweight.

Puppies should be treated at 2 weeks of age, 5 weeks of age and again before leaving the breeders' premises.

Treatment may also be required at 8 and 12 weeks of age. Thereafter, frequency of treatment can be reduced unless the pups remain in kennels where reinfestation occurs more readily.

1 ml per 4 kg bodyweight daily from day 40 of pregnancy continuously to 2 days post-whelping (approximately 25 days) (= 25 mg fenbendazole/kg bodyweight daily).

Practical dosage recommendations:

For dogs weighing over 40 kg, an extra 1 ml is required daily for each additional 4 kg bodyweight.

As treatment of pregnant dogs is 98% effective, puppies from these dogs should themselves be treated with a three day course at 2 and 5 weeks of age.

Pregnant cats can be safely treated with this product but only require a single treatment at the routine adult dose rate. Administer 1 ml per 1 kg bodyweight as a single dose (=100 mg fenbendazole/kg bodyweight).

For the treatment of clinical worm infestations in adult dogs and cats or Giardia spp. infections in dogs administer 1 ml per 2 kg bodyweight daily for 3 consecutive days (= 50 mg fenbendazole/kg bodyweight daily for 3 days).

For the control of lungworm Oslerus (Filaroides) osleri in dogs administer 1 ml per 2 kg bodyweight daily for 7 consecutive days (= 50 mg fenbendazole/kg bodyweight daily for 7 days).

A repeat course of treatment may be required in some cases.

For the control of lungworm Aelurostrongylus abstrusus in cats administer 1 ml per 2 kg bodyweight daily for 3 consecutive days (= 50 mg fenbendazole/kg bodyweight daily for 3 days).
