Consult your veterinarian if a dose is missed

The recommended dosage for Safegaurd (fenbendazole) is 50mg per kg (2.2 lbs). This translates into 1100mg (1.1 grams) of fenbendazole for a 50 pound dog. A tube of Safegaurd horse paste contains 25 grams of wormer @ 10% concentration = 2.5 grams of fenbendazole per tube. Therefore, the proper dosage would be just shy of 1/2 the tube. Fenbendazole is much more effective when given 3 days in a row so it would take nearly 1 1/2 tubes to worm a 50# dog properly. I have included a link below that gives the proper dosage. Most folks have a hard time giving a 50# dog enough wormer for a 500 lb horse.

The most economical way to administer Safegaurd is the liquid goat wormer. You can worm nearly 4 50# dogs for 3 days in a row with a 120ml bottle that cost about $17.

This link is for Panacur, but it is still fenbendazole.... scroll down to where it says ingredients and it gives the dosage.

The dosage for dogs is usually much higher than other species for fenbendazole

Elizabeth – Safeguard’s active ingredient is fenbendazole. Safeguard and Panacur both have fenbendazole. The Safeguard paste is for equine. It is an off label use for canine. The dosing is different. That is the difference. Safeguard does not want people to know what the correct dosing is for dogs. They make a separte formula for dogs that is much more costly!!


For cats and dogs, fenbendazole should be administered at a dose of 25 mg per pound (50 mg/kg) daily Fenbendazole (Panacur), well known for its effectiveness against a variety of intestinal parasites, also appears to be very effective against Giardia. In a controlled trial at Cornell 6/6 dogs were effectively treated. The same dose that is used to treat roundworms, hookworms, whipworms, and the tapeworm Taenia pisiformis (22 mg/lb orally once daily for 3 consecutive days) is used to treat Giardia. If the infection is not cleared on this regimen, a longer course of therapy is used (5 to 7 days). Fenbendazole has a proven track record for being very safe and is thought to not have any teratogenic effects. Fenbendazole is therefore the drug of choice for treatment of Giardia in pregnant animals.

Active Ingredients (in Each Dosage Unit):

You have a 10% solution which is 100mg/ml. So the dose for a dog would be .23 ml per pound or 2.3 ml per 10#. A 50# dog would get 12 ml. The dosage for dogs is usually much higher than other species for fenbendazole. In this case, the dog dose is 10X higher than the goat dose (5mg/kg) so a 100# dog would get 23 ml of Fenbendazole (Safeguard) 3 days in a row.
