how old the dog can be undergo on purgation?

Normally the first wormings are done while the babies are still with their mom... I start at 4 weeks and worm them every two weeks until they leave for their new homes at around 10 - 12 weeks. After that it is recommended that a fecal exam for worms be done with every vaccination appointment... usually at 13 weeks and again at 17 weeks or so. After that, have a fecal exam done yearly and worm if necessary.
