Jack you are correct I posted pg. 356
I think we are just interpreting the dosage differently, or the book is contradicting?
I found the section you posted "Anthelmintics" and read over "Benzimidazoles" which is the class of drug febendazole is considered. It states that febendazole is a prodrug because it has a longer half-life, it is not rapidly metabolized into an inactive product. Then goes on to point out what you stated above about the digestive system of a ruminate or horse. (I know I'm stating the obvious here, and you know this!)
I'm not trying to disprove what you say at all Jack, but I would like this to be clear for myself. It is matter of using twice as much drug at twice the cost.
I found this article about febendazole dosage in dogs I thought I'd share. Link: http://wildpro.twycrosszoo.org/S/00C...nbendazole.htm
