If a pregant dog has worms and you worm her, what effect does
it have on pups ,will it hurt them?

Hi Guest

Panacur is licenced for pregnant dogs from, if I remember correctly, day 42. The instructions will be on the bottle as you give them some every day until two days after whelping although mine never eat for a couple of days so always miss the last few doses. The amount depends on the weight.

I have not found any problem with the pups or pregancy from following this regime
