Worming a puppy?

Mugser

Puppy born 4 weeks ago, still feeding off the bitch (terrier size, in case that matters) I've noticed a string of what I can only presume are worms in the puppy box. (I wont post a pic in case people are eating:p) Question is 3 fold: (1) How old does a puppy have to be before administrating worm medication? (2) What medication will I get? and (3) where will I get it?
Any other tips would be most welcome too.
Thanks in advance.

You can worm them from 2 weeks up.

Encysted larvae are often present and can be passed to the puppies, while in the uterus and by nursing. Make sure the worming medication you get is for puppies, if you're unsure the safest way is to take the puppies to the vet. Puppies have to have one worming tablet each month for a year and then it's every 3 months afterwards.

Make sure you worm the bitch as well so she wont be able to pass it to them again.

Puppies 4 to 12 weeks of age should be wormed every two weeks.

From age 12 weeks to 6 months puppies should be wormed monthly

From 6 months onward dogs and puppies should be wormed every 3 months.
