I probably should have been more specific on my original post. I realize that Ivermectin and Fenbendazole (when appropriately dosed) are safe for pregnant bitches. The question related to dosing with Fenbendazole for 20 plus consecutive days. (Which is much more aggressive than anything I have ever read). Here is an example of one of a handful of different references I read about it: http://www.ncbi.nlm.nih.gov/pubmed/12002591
My interest is to pre-emptively hit any potential for giardia in the bitch or pups since Fenbendazole has proven efficacy on giardia. I have several different dogs through my facility throughout the year and had a giardia-positive pup show up for some long-term boarding just last week. I also have a bitch expecting in a couple weeks. Both the pup and expecting bitch have been started on Safeguard.
I've consulted my vet....I was just wondering if anyone was regularly trying such an aggressive anti-parasite program...........
I usually run Fenbendazole through all my dogs in April and November......Ivomec once a month from April through October.
