Amounts to be administered and administration route
Routine treatment of adult dogs and cats
Administer 100 mg fenbendazole per 1 kg (2.2lb) bodyweight as a single dose.
Practical dosage recommendations:
1 g sachet /dose Treats 2 kg (4.4 lb) bodyweight as a single dose (1.1 – 2.2 kg)
1.8 g sachet / dose Treats 4 kg (8.8 lb) bodyweight as a single dose (2.2 – 4.4 kg)
4.5 g sachet /dose Treats 10 kg (22 lb) bodyweight as a single dose (5 – 10 kg)
For dogs weighing over 10 kg (22 lb), additional sachets are required according to the additional bodyweight.
Assess bodyweight as accurately as possible and then administer one or a combination of the above sachets, which most closely doses this bodyweight. The dose should be administered by mixing into the feed.
e.g. For a 9 kg dog = 2 kg dose (1 g sachet) + 4 kg dose (1.8 g sachet) + 4 kg dose (1.8 g sachet).
i.e. one x 1 gram sachet + two x 1.8 gm sachets. (10 kg dose)
or, one x 4.5 gram sachet (10 kg dose)
Treatment should be repeated when natural re-infection 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.
Weaned puppies and kittens under six months of age
Administer 50 mg fenbendazole per 1 kg (2.2 lb) bodyweight daily for 3 consecutive days.
Practical dosage recommendations:
1 g sachet /dose Treats 4 kg (8.8 lb) bodyweight (minimum weight 2.2 kg) dosed daily for three consecutive days (2.2 – 4.4 kg)
1.8 g sachet / dose Treats 8 kg (17.6 lb) bodyweight dosed daily for three consecutive days (4.5– 8 kg)
4.5 g sachet /dose Treats 20 kg (44 lb) bodyweight dosed daily for three consecutive days (10– 20 kg)
For dogs/puppies weighing over 20 kg (44 lb), additional sachets are required according to the additional bodyweight.

Puppies should be treated at 2 weeks of age, 5 weeks of age and again before leaving the breeder's 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 re-infestation occurs more readily.
Pregnant dogs

Practical dosage recommendations:
1 g sachet /dose Treats 8 kg (17.6 lb) bodyweight daily approx. 25 days
1.8 g sachet / dose Treats 16 kg (35.2 lb) bodyweight daily approx. 25 days
