I think I saw a worm...the first time ever. Puppies are 4 weeks old and have been wormed once. So I just wormed again and saw that the wormer med expired in 2007. I don't breed often. What now? Worm again witrh new stuff? Other bottle expired 2009.
Maybe just call the vet.

Worm with Panacur!

Panacur is a great product. It's considered very safe and should take care of your problems. It even takes care of giardia. For coccidia, use ponazeril.

I see Panacur C available on line--says for puppies 6 weeks and older...safe for little pups too? Is the "C" the same and just Panacur?

BTW...when I called the vet they said it was ok even though expired..should work

No idea what Panacur C is - I usually just use liquid Safeguard wormer - 10%. Same ingredient (fenbendazole), but no prescription needed.
