http://www.coopersanimalhealth.com.au/Label/sp/Panacur25_label.pdf If this is what you have as a product then follow the goat and sheep as it is an accurate single dose . 70 kg would be 14 ml , it clearly states 1 ml for 5kg or 5mg per kg ,or 25 mg per ml of fenbendazole . 25 mg per ml x 14 ml = 350 mg or 1dose . Fenbendazole must be used in double doses for encysted small strongyles so this 14 ml would be taken twice a day to achieve 10 mg per kg of fenbendazole . You weigh 70 kg x 10 mg = 700 mg . Added benefits from fenbendazole , kills fungus, giardia and candida . I took a 2week double dose to start off with and no ivermectin during fenbendazole . Then I did 5 day double doses every 2weeks . I also did ivermectin 3days on and 1day off in between fenbendazole doses . I did this from jan to June , I am now doing moxidectin thru summer in Florida which is our nematode dormancy season. I am also sweating out the encysted ones with our 100 plus degree heat index . The heat causes the encysted ones to burn up their reserves ,tricking them out of dormancy and moxidectin ensures their first meal will be their last. Hope this helps , happy hunting and wish you well. P.S. I would use this product as long it is oral and not a drench.
