Have used Panacur 10% for years. Don't worry if you find your bitch misses a couple of days because she just won't eat. I start on day 42 through to 2 days after whelping. I poach white fish in milk, and just add the Panacur suspension. I hate forcing it down them with a syringe, and most of it ends up spit in my face. :-(
The bitch is then done when pups are 14 days, and the pups are dosed over 3 days. The bitch needs to be dosed on 1 day only, at the adult dose rate. Remember that the instructions for dosing during pregnancy is actually 1 quarter dose. So, although it sounds a long time, the dose rate is very small. I can't recall the exact statistics, but I know that they experimented with doses way over the top, with no problems at all.
