After giving de-worming medicine panacur to your puppy should the expelled worms be dead Day 23 excreted roundworms still wiggling How long until not contagious-infectious?

Our vet says Worms can live out side the body of a host and that they live in the dirt. More importantantly your should follow up on the worming again because eggs hatch every 2 to 3 weeks ( in cycle 21 days )That is why your seeing live worms.... PS switch worming meds go from panacur to drontal to stronj...opps spelling I think. at about the 3rd worming you may have them all gone. but even then adult dogs get dewormed. Heart guard ...

Anyways hope this will help D Miller - www.millersboxers.com
