Sorry about this guys I thought I was up to speed but one of my puppy buyers has been told different.

The litter born 26 Nov was wormed three day course panacur 10% 22.23.24 Dec. they were wormed again 8.9.10 Jan Panacur 10% and stonghold treatment applied 16th Jan (also does adult round worms).  When his new owner took him to vet for vax the vet gave a tablet to worm the little mite again on 23rd Jan. 

I always advise my people to worm again at twelve weeks or a month after the last worming.  Now I am totaly confused has anyone else been told about worming again after one week.  Three doses seems a lot to me in a total of 9 weeks, not counting the stronhold.
