What is Vetina CanWorm Suspension?
Vetina CanWorm Suspension is fenbendazole 100 mg/ml in 30 ml bottle from Vetina Healthcare, made for canine routine deworming and giardia treatment. Fenbendazole is a broad-spectrum benzimidazole used in veterinary medicine since the 1970s. It is one of the most reliable single-agent dewormers in canine and feline practice and is a standard component of horse and livestock parasite-control programmes.
Mechanism of action
Fenbendazole binds β-tubulin in parasite cells, preventing microtubule polymerisation. This blocks parasite glucose uptake and depletes glycogen stores — the worm starves over 2–3 days. The drug has very low oral bioavailability (~1–2% in dogs and humans), which is therapeutically advantageous: high concentrations in the gut lumen where intestinal worms live, near-zero systemic exposure.
Fenbendazole is metabolised in the liver to oxfendazole (the sulfoxide) and a sulfone metabolite, both of which retain anthelmintic activity. Excretion is primarily faecal.

Frequently Asked Questions
How do I dose Vetina CanWorm Suspension for my dog?
50 mg per kg of body weight, once daily for 3 consecutive days. A 10 kg dog needs 500 mg per dose; a 25 kg dog needs 1250 mg per dose. For a 100 mg/ml suspension this is 5 ml and 12.5 ml respectively. Repeat the 3-day course at 3 weeks if needed.
Can my puppy take Vetina CanWorm Suspension?
Yes from 6 weeks of age. The standard puppy schedule is fenbendazole at 2, 4, 6, 8 weeks then monthly to 6 months. Lower doses are used in pregnant bitches.
Will Vetina CanWorm Suspension kill all worms my dog has?
Fenbendazole covers the major intestinal nematodes (roundworm, hookworm, whipworm) and Giardia. It does NOT reliably kill all tapeworm species — for tapeworm cover, add praziquantel or use a combined product.
What if my dog vomits the dose?
If vomiting occurs within 1 hour, repeat the full dose. Beyond 1 hour, the drug is partially absorbed; do not redose — just continue the schedule.
Can I give Vetina CanWorm Suspension to my cat?
Yes, at the same 50 mg/kg single-daily dose for 3 days. Cats often dislike the taste of suspension; try mixing into a small amount of tuna or wet food.
Is fenbendazole safe in pregnant dogs?
Yes. It is one of the safer dewormers in pregnancy. Standard protocol is 25 mg/kg daily from day 40 of pregnancy through 14 days post-whelping — this prevents transmammary roundworm transfer to the puppies.
Can humans take Vetina CanWorm Suspension?
No. Vetina CanWorm Suspension is a veterinary product not approved for human use. For human anthelmintic needs use albendazole, mebendazole, ivermectin, niclosamide, or praziquantel from this catalogue. The viral ‘fenbendazole for cancer’ story has no controlled human-trial evidence behind it.
Should I deworm a healthy-looking dog?
Yes. Most intestinal worms cause minimal visible symptoms in adult dogs but shed eggs into the environment, infecting other animals (and posing zoonotic risk to children). Routine 3-monthly deworming is standard veterinary advice in most countries.
Can I combine Vetina CanWorm Suspension with flea and tick treatment?
Yes. Fenbendazole has no negative interaction with topical flea/tick treatments (frontline, advantage, isoxazolines). Many comprehensive parasite-control plans combine the two.
What about my puppy’s littermates?
Treat all puppies in the litter on the same days. The mother (bitch) should also be on the lactation deworming schedule. Bedding should be cleaned to reduce environmental egg load.
